Take It From Someone Who Lives Multiple Cats, You Don't Want To Miss These Prime Day Deals
Amazon Prime Day is here! There are more deals than you could ever begin to look through on your that's where we come in. 49% off a self-cleaning automatic litter box that'll clean up after your kitty so you don't have to (because scooping gets real old, REAL fast). It'll help keep your home smelling fresh *and* keep your cat happy, because (like us humans) they prefer to use a clean "toilet." Reviewers vouch for this as a nice alternative to the much pricier Litter Robot, AND it comes with a lifetime warranty. The best deal is for this bundle with the gray litter box, which comes with a three-pack of litter bags to get you started — nice!Promising review: "I'm absolutely loving this litter box. I've had THE Litter Robot for 4 years and I purchased this item a month ago. This one is so quiet and it takes up about half the space. My cats love it. I love that it's so much easier to remove the bag. Since the entry is so much lower to the ground the cats don't 'grab' when they jump out like with the other box so there's less mess around the opening of the box. Also this has a lifetime warranty and my other box only had a year. I've purchased a new globe for the old box which was almost the cost of the new box. Oh yeah, and the cost is a lot less than the Litter Robot! I've already recommended this item to my other cat parent friends." —Christine $197.58 (typically $389.99; best deal is on the bundle) — and shop all Pet Cove deals here Or 37% off another well-rated automatic litter box sporting a spacious, open-top design that won't make them feel trapped while doing their business — now your anxious kitty who jumps at the slightest noise can keep a 360-degree of their surroundings, and you can still reap the benefit of being waaay lazier about scooping (just empty the waste drawer every 1–2 weeks as needed)! Promising review: "I can't stress enough how much this litter box has changed my life. It's incredible. I'll literally never scoop litter again. My cats love it too. I chose this over the Litter Robot 4 because it's easier to clean and I just love the open design. The setup takes less than five minutes as it comes assembled (just put the legs on) in the box. And you can literally derp clean this thing and have it back to normal in 5 minutes too. If you're on the fence, look no further." —Thelu's KnobPrice: $379.99 (originally $599.99) Up to 56% off a Furbo Cat Camera, which rotates 360 degrees with HD video quality (and even night vision) so you can check in on your kitty and give them treats while you're away! You can even speak to them using the two-way audio feature, and you can receive activity alerts for things like meowing, vomiting (!!), and humans being around (so you'll know when your cat sitter finally drops by). Note that certain features are added with the optional $6.99/month Furbo Cat Nanny subscription (slightly cheaper if you choose to be billed annually), including the real-time alerts and video history. Without the subscription, you can still check the live view, interact via two-way audio, play with them using the attached feather toy, and toss treats. Promising review: "I got the Furbo Cat Camera to help me watch my cat, Morse, when I'm out of the house, because he's a rescue cat and has some behavioral issues. It's been a godsend to just open the app and see what he's doing, no matter where I am — if he's up to mischief, I distract him with a treat or speak to him through the camera. Morse also enjoys batting the attached feather toy, and the ability to rotate the camera back and forth definitely makes it a more intriguing game for him. I love being able to entertain him from afar; it's saved more than one houseplant already! Plus, the Meowing Alerts keep me clued in on his activity. He's not a very vocal cat, so meowing indicates there's something I should check in on. Highly recommend for cat parents looking for peace of mind and new ways to look after their pets." —ElissaPrice: $44 for the model that requires a 3-month-minimum subscription (originally $99), and $129 for the model that *doesn't* require a subscription (originally $210) 20% off a Feliway calming diffuser starter kit *with* an extra six months of refills, saving you $23 on the bundle. This stuff can be a game changer if you have cats who don't get along, whether one of them is new to the household or a life change has caused them to become aggressive. This plugs right into your wall and releases pheromones that mimic a nursing mother's, helping to not only calm cats down but also encourage social acceptance of each other. The starter kit gets you the diffuser head and one vial of Feliway, which lasts 30 days — and the Prime Day bundle gets you an extra six months of refills, so you'll be stocked for a while. Keep in mind that if you're introducing a new cat, you should *still* take proper precautions like keeping them separate for a while, doing smell introductions first, etc. Promising review (for the starter kit): "I can't express enough how much this has changed mine and my cats' lives. Merging two households wasn't easy on the cats. One male cat had a hard time moving into a new house with new pets. He had terrible behavior problems and would cause us and the other cats a lot of stress. His bullying led to the other two cats having health problems. He would get into moods where he would chase and attack the others and would not let up. We tried everything the vet suggested to reduce theses incidences, but getting Feliway was the only thing that worked. He is a completely different cat now. He is calm and his outbursts rarely happen. He has become a couch cat and has turned into the sweetest boy. The other cats aren't stressed anymore and neither are we. We have three diffusers in the three rooms we have had incidences in. It definitely has more of an affect on the male cats than the female. If you aren't noticing a difference with one diffuser I would suggest getting a second. We couldn't believe that this one product could fix everything, but it did. If he starts to act out again we check the diffusers, and sure enough, one of them will be out. If your cats are having any behavior problems or stress please try this!" —Kristine SpencerPrice: $91.97 (originally $114.98) — and shop all Feliway deals here 21% off (plus an extra 10% off coupon) an air purifier to help you manage indoor allergies from pet dander and those awful smells that waft around from the litter box — and if you've ever seen one of your cat's eyes watering, it's possible the poor thing could have allergies itself. This works quietly in the background to clean your air — all you have to do is replace the HEPA filter as needed! I picked this air purifier up a couple years ago to help manage the ~smell~ that sometimes wafts from my cats' litter box when it starts to get full, and to help keep my NYC apartment air cleaner in general. I'm also (lol) extremely allergic to cats, and though I get allergy shots for this, it's also nice to help cut down on the pet dander for myself and any visitors with allergies. This thing makes a DIFFERENCE. It cuts down on any noticeable smell from the cats, my air feels cleaner, and my allergies are usually non-existent in the apartment. Oh, and it's fairly quiet — it basically functions as white noise, which can be handy if you run this at night in the bedroom on your usage and environment, it's recommended to replace the filter every 3–6 months — replacements are available on Amazon. (You can see the difference between my old filter and a new replacement one above!) Note: Be sure to take the plastic off the filter before placing it in the unit!Price: $44.09 (typically $61.99; available in two colors — click "redeem" on the 10% off coupon for the full discount)Alternate deal! It's slightly more expensive, but if a Levoit air purifier has been on your wishlist, you can snag one for 22% off for Prime Day ($69.97, the lowest price it goes for). 30% off a chic, modern Mau cat tower (only a few bucks more than it was during Black Friday) — direct discounts on Mau products are rare, so jump on it if you're looking for a small but high-quality tree that's built to last. Mau trees are made with real wood (they're handcrafted from literal tree branches, so every piece is one of a kind), and they sell replacement parts for everything, unlike so many cheap cat products you eventually have to just toss. Plus, it won't clash with your home's aesthetic. I have a different Mau cat tree (one not sold on Amazon) and absolutely love it, as do my cats! It's one of those upgrades that once you make, there's no looking back — I hope to pick up a second one of their trees in the future!Promising review: "Really aesthetically pleasing kitty tower. This would go well with any modern or boho decor. The platforms are plush and cushioned well and a true white. Perfect height by my bedroom window where I wanted something nicer looking than the usual cat tower. This really fit the bill! Plus, it feels very sturdy — the wooden tree sections are pretty heavy, and both my cats were able to stand on it without any wobbling at all." —GigiPrice: $132.30 (originally $189; deal available for two colors) 25% off (plus an extra 7% off coupon) the *iconic* ChomChom pet hair roller — for the uninitiated, this cleaning product traps pet hair inside without the use of any sticky tape, and it works wonders on fur-covered couches and chairs. Full disclosure, this definitely isn't the best deal we've ever seen on the ChomChom during Prime Day, but it is cheaper than its everyday Amazon price — so if you're *struggling* with pet hair covering everything you own, you may as well snag this while the tens of thousands of 5-star Amazon reviews are reason enough to add the ChomChom to your cart immediately, let me add my own personal review to the stack. I've been using the ChomChom for quite a while now and took the photos above to show just how quick, easy, and effective this roller is. It took 10 seconds to rid my velvet couch ottoman (yes, velvet...a terrible cat owner choice, I know) of the hair my two gray kitties are constantly leaving everywhere. It takes a bit of practice to get the hang of using this roller — at first, I thought you only brushed down in one direction, and was confused why it wasn't picking up hair. It's important to do a push-and-pull brushing in *both* directions so it actually pulls the hair inside, which does require you to apply a bit of pressure. Afterward, you'll just dump out the hair that's been trapped inside. The ChomChom is best for large flat surfaces like couches and $17.43 (typically $24.99; available in two colors — click "redeem" on the 7% off coupon for the full discount) — and shop all ChomChom deals here Up to 30% off a bottle of Zesty Paws Wild Alaskan Salmon Oil, which adds essential fatty acids to wet or dry food so they can have the most luscious, shiny coat. Reviewers say it also helps with shedding! Promising review: "My kitty loves this stuff!! I squirt a little on top of her food, and she makes sure to lick it all off before even thinking about taking a bite out of her pâté! My main purpose for purchasing this was to relieve my kitty's constant shedding!! She's a short to medium haired cat, but no matter how much I brush her, the shedding is relentless! I've only been using this oil for a week, but I've already noticed a HUGE improvement after adding this oil to her diet and switching her to wet food!! There's still some minor shedding, but nowhere near as much as before, so I'm grateful!! I haven't experienced the texture issues with the oil that others have mentioned. My oil came with a pump, and the texture has remained loose, smooth, and oily." —TytiannaPrice: $20.97 for a 16-ounce bottle (originally $29.97; also available in a smaller size) — and shop all Zesty Paws deals here 53% off a cat DNA test (it's from Shark Tank!) that'll unlock a whole new world of info about your cat, like whether that gray baby is actually a Russian Blue or some kind of mix. It'll also give info on health markers and traits your cat is likely to have based on their breed — so now you'll know *why* your kitty is so uniquely lovable! Promising review: "I purchased this kit because I have an 18-pound green-eyed, long-haired cat, whom everyone asks me about. 'Is she a Maine Coon?' 'Is she part Maine Coon?' I had no idea as to her lineage, as I found her struggling for her survival on the street and had no idea who her parents were. She turned out not to be a Maine Coon, but showed similar ancestry to rag dolls. Believable, as she's very people-friendly and almost acts like a dog. However, the most important part of this test is the health reports. I've sent a copy to her veterinarian, so that we can be on the lookout for anything she may be predisposed to and to have the vet give suggestions as to how to avoid certain outcomes. I'm very happy with the test and recommend it to anyone with concerns about their cat's health or curiosity about their lineage." —MadoucPrice: $74.99 (originally $159) 34% off a Bissell Little Green carpet and upholstery cleaner if cat stains and accidents are part of your daily life, and you've almost given up on that one rug they seem to have designated "the puke spot." This TikTok-beloved cleaner is a holy grail product for many pet parents, capable of sucking out stubborn stains as well as dust, dirt, and fur. It's *your* house, not the cats' — time to reclaim your furniture and floors. Yes, that's cat diarrhea on the reviewer's nice white rug above. The Bissell truly works review: "I found the Little Green machine because of a TikTok video; someone was cleaning their car seats and the water was absolutely disgusting, so obviously I was like I HAVE TO TRY THIS. So I ordered one and it was everything I ever hoped and more! We have three cats in the house whose favorite pastimes are puking, peeing, and occasionally stepping in their own poop and running across the only carpeted room in the entire house, you know how cats are. Anyway, this thing works SO well it tackles all of that and every other mess I've made to date! It's small enough it doesn't feel like a huge hassle to store it or pull it out, but also holds enough water I don't have to constantly run to refill it. I think it might be magic and I have a slightly unhealthy attachment to it at this point. I'm not sure if its always the case, but the box came with a coupon for two containers of the cleaner through Bissell too, which was a huge bonus!" —StephaniPrice: $81.99 (originally $123.59) $10 off a Wi-Fi-enabled automatic food dispenser to eliminate any lingering worries over if you've fed your fur baby or not. The 5-liter model can store about *5 pounds* of pet food, which can last cats up to 20 days (aka you won't have to refill it constantly). And you can program their meals from anywhere using a smartphone app! Promising review: "We are vacationing for a month in Arizona and wanted an automatic feeder for our cat in case our cat sitter couldn't get to our house. We can add an extra feeding remotely. We are very pleased with our purchase. We can easily adjust the amounts and times of feeding, even from a thousand miles away. When the cat hears the voice say 'mealtime,' she comes running. We are able to control her diet because we aren't arbitrarily feeding her." —Jan DPrice: $59.49 for the black feeder (typically $69.34; also available in another color and other models on sale at different discounts) 45% off a top-entry litter box discreet enough to place in multiple rooms if you have more than a few cats and really need to make sure they have ~options~. The grooved lid at the top helps remove leftover litter particles from your cat's paws as they climb out, and if you have a dog in the house who likes to go digging in litter boxes, this design can also keep them out of your cats' poop spots. Reviewers say it works for both small and bigger cats alike! One reviewer's tip: Make sure the side without the grooved lid is facing a wall so that cats can't jump out that way (the grooved side is what prevents litter tracking).Note that if you have a senior cat with limited mobility, you'd want to provide a litter box with low, easy access for that review: "We have three cats and have to manage a silly amount of cat politics. We've learned that having a higher number of litter boxes, and spread to multiple locations, cuts way down on bullying and helps cats to feel safe, [as they are] instinctively territorial about where they put their scent and feel vulnerable when they're 'in the act'. This cat box helps to be able to have boxes in rooms of the house where a cat box would feel garish, not to mention the litter mess. It took a little while for my cats to try it out, but they're using it now and don't get to kick the gravel out everywhere (I swear they do it on purpose)." —DismPrice: $24.96 for the white and beige style (originally $44.99) 20% off a double-layered litter mat because of the sheer volume of litter being tracked out of the litter box on a daily basis. It has a honeycomb design that catches and traps litter so it doesn't scatter across your floor. You can then press in on the sides to open up the mat and dump the trapped litter back into your litter box, or slide it into the trash can, whichever you prefer! I've been using this trapper mat for ages now, and while it's pretty much impossible to eliminate all litter from your home if you own even one cat, let alone multiple, this mat has made keeping the floor of my litter box room MUCH more manageable. Unlike other mats, where the litter just kind of sits on top and eventually gets kicked elsewhere, this mat is designed so that the litter falls through the holes and stays inside the mat until you're ready to dump it. It's made out of an EVA material that's supposed to be gentle enough for cat paws, and my two kitties don't seem to have a problem walking on it. I *highly* recommend getting the larger 30-by-24-inch mat to extend the coverage area (and thankfully, it's a little cheaper right now for Prime Day) — I initially got the smaller one but went back for the larger size, and it's perfect. Note that the mat will probably have a fold down the middle when it first arrives, but just give it some time and weigh it down with something if needed; it'll lay $19.99 for the larger size (originally $24.99; available in three colors) 20% off an Uproot carpet rake, aka the extra-long version of their popular pet hair removal tool — this version lets you tackle your carpets and rugs without having to kneel or bend over and covers a larger surface area faster (the dual-sided edge and telescopic handle make it so easy). It's infinitely reusable, so it's worth the upfront cost (especially while it's on sale) if your home is covered in pet hair. It's a good idea to use this before you vacuum! This gets out embedded hair that even a vacuum can't reach. Just avoid using on delicate knits and fabric — it's meant for sturdier things like carpets, rugs, stairs, couches, cat towers, and review: "I love this brush. I have two dogs that shed a LOT. I am always vacuuming but felt like I wasn't getting it all out of the carpet. I used this brush and essentially got a small dog's worth of hair out of the carpet that otherwise looked clean. It works so easy to pull up hair that you otherwise wouldn't see. It's easy to clean because you just pull off any hair that sticks to it. The quality is great, and even with some aggressive scraping, I haven't had it bend on me. It's easy to store; I just hang it in my laundry room with my other brooms and pull it out a couple of times a week before I vacuum. This is the BEST pet hair tool out there." —TonyPrice: $39.98 (originally $49.99) — and shop all Uproot Clean deals here 25% off some Churu chicken-flavored bisque (matching its lowest-ever price from Black Friday) — if your cat goes wild for their popular squeeze tube treats (and I've yet to meet a cat who doesn't), they'll love this delectable side dish that's packed with moisture and gourmet flavors. The Churu deals on the whole are not great this Prime Day, featuring only slight markdowns on their everyday Amazon price — *but* this one saves you a few bucks per 12-pack, which is pretty decent! Like their squeeze tube treats, this bisque is intended to be used as a side dish, topper, or treat, not as a meal review: "My two cats are total Churu fans, and this bisque has been an absolute favorite! They go wild for the tuna flavor, and I love that it has a mild scent that doesn't overpower the room. The smooth, creamy texture makes it easy to sneak in any medication, which has been a game changer for us. Plus, since we started using it, I've noticed their coats are softer and healthier-looking than ever. One of our kitties even has a softness we didn't see when we first adopted her. They both devour it and usually end up in a happy food coma afterward! Five stars from my cats." —ReadingbythepoolPrice: $8.82 (typically $11.76; same deal available for the tuna recipe) — and shop all Inaba deals here 24% off a hide-and-seek interactive cat toy if you have at least one super active kitty who wants to play right when you sit down to work every day (🙋♀️), or they're constantly egging on their older sibling who just isn't interested. Press a button to cycle through its settings, activating a fluttering butterfly at the top or a spinning feather toy underneath its removable cover — or have both of them running at once for max stimulation. Both of my cats like this toy, but Chicho (my super active younger cat) goes wild for it every single time. He really likes batting at the butterfly (as shown above), whose erratic movements keep him totally engaged, but he also loves laying on his side trying to catch the feather that zooms left, right, and all around. The fact that most of the feather toy is hidden underneath the patterned cover (so they can't see what's controlling it) is a genius design, and I'll also mention that my cats haven't been able to destroy this toy yet either — though the brand does sell replacement parts thankfully. The battery lasts a long time, and it charges conveniently via USB-C, which I appreciate!Price: $23.73 (originally $31.23) — and shop all Potaroma deals here

Litter-Robot 3 Vs. 4: The Big Differences, Based On Cat Testing
We added more information about each litter box and expanded our FAQ section. We updated specs and pricing, and added a chart comparing the two models. We updated pricing and spec information and added details about our expertise on this topic. Since the first Litter-Robot self-cleaning litter box launched in 2000, the company has released numerous models that improve on the original's design. The brand's current flagship model is the Litter-Robot 4, while the Litter-Robot 3 Connect (released in 2017) remains an incredibly popular bestseller. We're going to break down the similarities and differences when comparing the Litter-Robot 3 vs. 4. Both are Wi-Fi–enabled and have advanced features that detect when your cat is using the bathroom and when the waste drawer needs to be emptied, for example. I live in a multi-cat household, and my three cats use both models regularly. While the Litter-Robot 4 and 3 Connect operate similarly, they have some notable discrepancies between their advanced safety features, sifting systems and odor control. To help you decide which automatic self‑cleaning litter box is a better fit for you and your cats, I break down the biggest differences between the Litter-Robot Connect 3 versus the 4 in this guide. But before I jump into the specifics, here's a general overview of each of the automatic litter boxes. Footprint: 24.3 x 27 x 29.5 inches | Weight (empty): 24 pounds | Minimum cat weight: 5 pounds | Entryway: 10.3 x 15.3 inches | Waste drawer capacity: 8 to 10 pounds (6 to 7 liters) | Available colors: Grey or Beige | Price: As low as $549 What you'll love: Keep in mind: There are two available versions of the Litter-Robot 3, and the Connect is the Wi-Fi–enabled model. The litter box connects to the companion app (called the Whisker app). Its best features include an effective safety system, reliable operation and waste drawer alerts. Note that when compared to the newer 4 model, it's louder, has a smaller waste drawer and doesn't control odor as well as the Litter-Robot 4. But the 3 Connect still has a lot to offer. It also costs $150 less than the 4 model, making it a good option for those who want the convenience of a self-cleaning litter box for less. Just note that cats must be at least 5 pounds to use this model, which comes in two colors: Grey and Beige. Footprint: 22 x 27 x 29.5 inches | Weight (empty): 24 pounds | Minimum cat weight: 3 pounds | Entryway: 15.8 x 15.8 inches | Waste drawer capacity: 9 to 10 pounds (7 to 8 liters) | Available colors: Black or white, plus eight interchangeable bezel patterns | Price: As low as $699 What you'll love: Keep in mind: The Litter-Robot 4 is the brand's newest model. Designed with multi-cat households in mind, the Wi-Fi–enabled litter box can accommodate up to four cats, thanks to a larger waste drawer and real-time monitoring of waste and cat litter levels. What's more, it has sensors that make it safe for felines as small as 3 pounds. Some other standout features of the Litter-Robot 4 vs. 3 Connect include a wider entryway and better, more advanced odor control. Whisker, Litter-Robot's parent company, calls the model the 'smartest, quietest self-cleaning litter box for cats,' and I have to agree. After testing several automatic litter boxes, including the Litter-Robot 3 Connect, I named the Litter-Robot 4 the best self-cleaning litter box overall. It comes in two basic colors, but you can upgrade the look with a colored bezel for an additional $50; colors range from a solid Lilac to a multi-hued Marble (pictured above). Now that you have a general overview of each of the models, here's how they compare in terms of setup, design, odor control, sensors, noise, deep cleaning and price. Setup for both models is a cinch. They come fully assembled, so you just have to take them out of the box and plug them in. The biggest difference between them is how you connect (and reconnect) them to the Whisker app. To sync the robots with the app, you scan a QR code that's on the machine. The Litter-Robot 3 Connect has the code in the back of the machine at the base. The Litter-Robot 4's code, on the other hand, is more conveniently positioned under the waste drawer. While this isn't a big deal for the initial setup, the positioning of the QR code makes a difference if the Litter-Robot disconnects from the app and needs to be reconnected. When I need to reconnect the Litter-Robot 3 Connect, I have to take it out of the credenza it's in and spin it around to find the QR code. With the Litter-Robot 4, I can just pull the waste drawer out and it's right there—no need to fuss with the positioning. I also noticed the app now walks you through an optional firmware check that keeps everything current. The design is the biggest difference between the Litter-Robot 3 Connect and 4—and it's not just about the looks. The construction also factors into odor control and how many cats the Litter-Robot can accommodate. Let's start with size. The Litter-Robot 4 is narrower than the Litter-Robot 3 Connect. While they have the same height (29.5 inches) and depth (27 inches), the Litter-Robot 4 measures 22 inches wide, compared with the 24.3-inch width of the Litter-Robot 3 Connect. At the end of the day, though, both of these Litter-Robots are big. Neither one of them is going to blend in seamlessly with its surroundings, so you have to be willing to sacrifice some space regardless of which model you pick. That said, the Litter-Robot 4 has some design upgrades that can benefit your cat. For starters, the entryway is much wider: 15.8 inches compared with the Litter-Robot 3 Connect's 10.3 inches. While my cats never seem bothered by the smaller opening of the latter, they definitely stick out of it more when they're doing their business; they just seem more comfortable in the Litter-Robot 4. The step into the entryway is also closer to the ground on the newer model, so it can be a better option for smaller cats or senior cats with mobility issues. (Whisker does sell ramps to make the taller step on the Litter-Robot 3 Connect more manageable, but with the Litter-Robot 4, you don't need it.) New buyers can also snag the Kickstart Kit, which bundles liners, carbon filters and odor-eliminators. Since the unit will likely be visible in your home due to its size, we like that the Litter-Robot 4 bezel now comes in eight swap‑in colors for quick style points. Another notable difference is the waste drawer. The Litter-Robot 4's drawer has an overall smaller footprint, though the area that collects waste is larger. This means you don't have to change the trash bag as often. The Litter-Robot 4's drawer also has a more rectangular shape, so waste spreads out more evenly. With the Litter-Robot 3 Connect, I often notice that clumps pile up in the center of the drawer, sending false signals to the sensors that the waste drawer is full. That doesn't happen with the Litter-Robot 4. Additionally, the trash bag fully covers the waste drawer in the Litter-Robot 4. The Litter-Robot 3 Connect has clips inside the waste drawer to keep the trash bag in place, but if it's not secured properly, it can cave in, creating a pretty annoying mess. This ties into design, but it's worth calling out odor control separately since it's one of the most vital parts of a litter box. While both models have carbon filters that need regular replacing, the Litter-Robot 4 is much more effective at trapping odors than the Litter-Robot 3 Connect, even with a full waste bag. Whisker says this is because the waste drawer is deeper and has a tighter seal. I rarely smell any waste in the Litter-Robot 4—unless it's fresh and still in the chamber before cycling. With the Litter-Robot 3 Connect, I can tell when it's full just by the way it smells. It's not as strong as an open litter box, to be sure, but things do get musky if you don't keep up with cleaning. Whisker now sells OdorTrap packs that clip inside either drawer; they're optional but noticeably help. The safety sensors also got an upgrade in the Litter-Robot 4. The Litter-Robot 3 Connect has weight sensors inside the globe that are triggered when your cat starts to enter or is inside the machine. These sensors stop or delay a cleaning cycle to keep your cat safe. While these have been reliable for me—the Litter-Robot 3 Connect has never, for example, cycled with my cat in the way—the sensors aren't technically as effective as the ones in the Litter-Robot 4. The newest version of the self-cleaning litter box has both laser and weight sensors so it can trigger the stop mechanism more readily, even if your cat is just peeking into the opening and hasn't put their full weight into the globe. While this ensures a faster response time, it also means that cats who weigh just 3 pounds can safely use the Litter-Robot 4. For comparison, the minimum weight for the Litter-Robot 3 Connect is 5 pounds. The Litter-Robot 4's SafeCat system pairs OmniSense lasers with weight plates, while SmartScale tech estimates which cat is inside based on weight data. Ongoing firmware updates have already dialed back oversensitivity, and each time the app prompts an update the unit gets a little smarter. These sensors are also so advanced that they can tell you which cat in a multi-cat household is using the litter box. While the scale isn't totally accurate—for example, it registers my 10-pound cat as weighing 7 pounds—it's still a useful tool for tracking the bathroom habits of each of your pets. If one of your cats isn't using the bathroom as often as they should (which can be a sign to call the vet), this feature can help alert you, says Jacob Zuppke, CEO and president of Whisker. While the laser sensors make for a safer machine, they also make it more sensitive—I've had more accidental triggers with the Litter-Robot 4 than the Litter-Robot 3 Connect. Though those incidents can be annoying, Zuppke says the brand's engineering team is always working behind the scenes to find the right level of sensitivity for these sensors. When I first got the Litter-Robot 4, the sensors were much touchier than they are now; thanks to firmware updates, they're a bit less reactive. And the sensors aren't the only part of the litter boxes the engineering team is constantly working on to improve. Any time you update one of the Wi-Fi–enabled models via the app, your litter box downloads any changes made. (It's the same concept as iPhone updates.) In addition to safety, the upgraded sensors have one other strength. When connected to the app, the Litter-Robot 3 Connect can only tell you if the waste drawer is full and needs to be emptied. Meanwhile, the sensors in the Litter-Robot 4 can monitor both waste and litter levels, so you can see exactly how full the waste drawer is and whether you need to add litter to the globe. Noise, or lack thereof, is another major difference between these two models. The Litter-Robot 4 is significantly quieter than the 3 Connect—I can barely hear it when it's running. The Litter-Robot 3 Connect isn't obnoxiously loud, but I'd say it's at least twice as loud as the Litter-Robot 4. (The sound level is about 50 decibels compared to roughly 25 decibels on the Litter-Robot 4's QuietSift cycles; similar to an electric can opener or a bathroom fan.) For what it's worth, the sound doesn't bother my cats at all. If you have more skittish felines, though, you may want to upgrade to the Litter-Robot 4 just for this. Deep cleaning takes about the same amount of effort for each model, and Whisker recommends you do the chore at least every three months, depending on how many cats you have. To really get the litter box clean, you have to take everything apart, thoroughly wash it and then let all the parts dry completely before reassembling it. It also requires vacuuming where the waste drawer sits, and there are lots of nooks and crannies in each of the machines that make this a pain. It takes at least an hour to do every time, and neither machine has an edge here. Perhaps the most obvious difference between the Litter-Robot 3 Connect and the 4 is the price. The Litter‑Robot 3 Connect retails for $549, while the Litter‑Robot 4 is $699. Financing through Affirm brings the newest model to about $44 a month, and you can add an extended three‑year WhiskerCare plan for $100. In my opinion, the upgrades are worth the higher cost, especially when you consider how long these litter boxes are meant to last. If it's within your budget, I recommend purchasing the Litter-Robot 4. While I'm happy with the performance of both machines, the newer model's design is such a massive upgrade. It's considerably better with odor control, able to hold more waste and much quieter, which I believe are worth the extra cost. Now, if you already own the Litter-Robot 3 Connect and it's working well for you, I don't think you need to toss it in favor of the Litter-Robot 4. If you want to add a second litter box, though, I'd go with the 4. And if you need more convincing, check out features director and cat mom Kim Peiffer's full review of the Litter-Robot 4. I'm Lindsay Boyers, the executive strategy editor at Forbes Vetted and a self-proclaimed cat lady who has three Siberian cat mixes terrorizing (er, enriching) my home. What's The Price Difference Between The Litter-Robot 4 And 3 Connect? On Whisker's website, the Litter-Robot 4 is priced at $699, compared to $549 for the Litter-Robot 3 Connect—a difference of about $150. Both models qualify for Affirm financing, so you'd pay roughly $44 per month over 16 months for the Litter-Robot 4. Buying bundles can narrow this gap a bit; for instance, the Litter-Robot 3 Connect Warranty Bundle starts around $599, while the Litter-Robot 4 Essentials Bundle is closer to $899—but the latter bundles typically come with extras like OdorTrap filters and a box of liners. What Is The Lifespan Of The Litter-Robot? Both Litter-Robot models are backed by one-year warranties, but in my experience, the lifespan is much longer. I've owned the Litter-Robot 3 Connect for four years and the Litter-Robot 4 for one and a half years, and both models are still going strong. According to Zuppke, keeping up with regular software and firmware updates through the app can help maximize the life of your Litter-Robot. Can Kittens Use The Litter-Robot 4? Yes, but Whisker recommends kittens weigh at least 3 pounds so the sensors can accurately detect them entering or exiting. Because the SafeCat system uses both weight sensors and laser detection, smaller kittens (even those under 3 pounds) might not always trigger the cycle properly—so keep a close eye or weigh your kitten if you're unsure. Many breeders introduce the Litter-Robot 4 around 10 to 12 weeks, when most kittens reach that weight threshold. Until your kitten hits the minimum weight, it's best to keep a traditional litter tray handy. Once they surpass 3 pounds, you can activate 'Kitten Mode' in the Whisker app, which delays cycling by 15 minutes for added safety. Does Litter-Robot Work With Any Clumping Litter? Both Litter-Robot models accept most standard clay-based clumping litters as well as many plant-based brands. However, extremely lightweight or purely crystal litters typically don't sift properly and can throw off the weight sensors. Whisker's own GreatLitter is a medium-weight clay litter that's ideal, but if you prefer plant-based options like corn or wheat, look for textures similar to clay; this helps the clumps stay intact during rotation. Avoid silica crystals, paper pellets and nonclumping litters, as they tend to either slip through the screen or clog the chute. When switching to a new litter, run a manual cycle first to ensure it works smoothly.

I didn't just stop scooping poop with the Litter Robot 4, it kept my cats healthy — here's how
If there's one unsung hero in my home that doesn't get enough recognition that it deserves, it's none other than Whisker's Litter Robot 4. I've had it for nearly 2.5 years, saving me countless time from getting down on my hands and knees to pick up after my cats. While I can't tell you enough how awesome it is to have this robotic litter box in my home to do the dirty duty of picking up my cats' poops, there's actually another feature about the Litter Robot 4 that I find equally as valuable. I honestly didn't think much of it the first few months, but its ability to monitor and track the weight of my cats has proven to be invaluable. In fact, it helped me to uncover a medical condition that was left undiagnosed for months with my cat Andy — and for that, I couldn't be grateful. Save yourself from constantly having to clean up after your cats with Whisker's Litter Robot 4. This robotic litter box not only cleans up after them, but its smart features allow you to track how frequently they use it and how much they weigh. With an assortment of accessories, it accommodates just about every feline no matter the breed, age, or size. As much as it takes the hassle away from cleaning up after my cats, the Litter Robot 4 has sensors that allow it to weigh them each time. At first, I didn't think much of this until one day I noticed my cat Andy started to feel a bit boney, especially around his back. He's been a hefty little feline, but I only realized his sudden weight change after I picked up my other cat Vader — who's even chonkier. For years taking Andy to the veterinarian, his weight would range from 10 to 12 pounds — so you can imagine my surprise to see it under 10 pounds through the Whisker app. What was even more of a shock was that his weight was trending downwards for the last couple of months, so we immediately took him to the vet. Our veterinarian eventually diagnosed him with IBD (Inflammatory Bowel Disease), so he was put on different medication and a new diet to see if he could pack on the pounds again. Long story short, it's been a struggle with his weight reaching as low as 8 pounds — but through the different remedies and medication, he's been on the upward trend the last 6 months. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. Through it all, the Litter Robot 4 allowed me to monitor any big changes week by week. This feature came in hand because we were able to see how well he responded to different remedies. Best of all, it gave me accurate results because it weighs him each time he uses it. Since he's older now, I also like how I can tailor my Litter Robot 4 to meet my exact needs. Most other robotic litter boxes my cats have tested are raised, so oftentimes they fly out of the litter box when they're done — splattering messy pieces of litter everywhere. With the Litter Robot 4, I have a fence installed at the opening to lessen this. I also like how there's a ramp that can help older cats with mobility issues to enter and leave it. Here's hoping for another 2.5 years of faithful service.

Litter-Robot 4 Vs. 3 Connect: The Big Differences, Based On Cat Testing
While there are other reputable brands in the space, the Litter-Robot name has practically become synonymous with self-cleaning litter boxes. Since the first Litter-Robot launched in 2000, the company has released numerous models that improve on the original automatic litter box's design. The newest and best-selling models are the Litter-Robot 4 and the Litter-Robot 3 Connect: Both are Wi-Fi–enabled and have advanced features that detect when your cat is using the bathroom and when the waste drawer needs to be emptied, for example. After regular use by my cats, here are the differences between the Litter Robot 3 vs. 4 models. My three cats use both models in my home regularly. While the Litter-Robot 4 and 3 Connect operate similarly, they have some notable discrepancies between their advanced safety features, sifting systems and odor control. To help you decide which is a better fit for you and your cats, I break down the biggest differences between the Litter-Robot 4 versus the Connect 3 in this guide. But before I jump into the specifics, here's a general overview of each of the automatic litter boxes. Whisker Footprint: 22 x 27 x 29.5 inches | Weight: 24 pounds | Minimum cat weight: 3 pounds | Entryway: 15.8 x 15.8 inches | Waste drawer capacity: 9 to 10 pounds (7 to 8 liters) | Available colors: Black or white, with various bezel options What you'll love: Keep in mind: The Litter-Robot 4 is the brand's newest model. Designed with multi-cat households in mind, the Wi-Fi–enabled litter box can accommodate up to four cats, thanks to a larger waste drawer and real-time monitoring of waste and cat litter levels. What's more, it has sensors that make it safe for felines as small as 3 pounds. Some other standout features of the Litter-Robot 4 include a wider entryway and advanced odor control. Whisker, Litter-Robot's parent company, calls the model the 'smartest, quietest self-cleaning litter box for cats,' and I have to agree. After testing several automatic litter boxes, including the Litter-Robot 3 Connect, I named the Litter-Robot 4 the best self-cleaning litter box overall. It comes in two basic colors, but you can upgrade the look with a colored bezel for an additional $50; colors range from a solid Lilac to a multi-hued Marble (pictured above). Litter-Robot Footprint: 24.3 x 27 x 29.5 inches | Weight: 24 pounds | Minimum cat weight: 5 pounds | Entryway: 10.3 x 15.3 inches | Waste drawer capacity: 8 to 10 pounds (6 to 7 liters) | Available colors: Grey or Beige What you'll love: Keep in mind: There are two available versions of Litter-Robot 3, and the Connect is the Wi-Fi–enabled model. Like the Litter-Robot 4, the litter box connects to the companion app (called the Whisker app), though it has more limited functionality. It's also louder, has a smaller waste drawer and doesn't control odor as well as the Litter-Robot 4. But the 3 Connect still has a lot to offer. Its best features include an effective safety system, reliable operation and waste drawer alerts. Additionally, the Litter-Robot 3 Connect costs $150 less than the 4 model, making it a good option for those who want the convenience of a self-cleaning litter box for less. Just note that cats must be at least 5 pounds to use this model, which comes in two colors: Grey and Beige. Now that you have a general overview of each of the models, here's how they compare in terms of setup, design, odor control, sensors, noise, deep cleaning and price. Simply put, setup for both models is a cinch. They come fully assembled, so you just have to take them out of the box and plug them in. The biggest difference is how you connect (and reconnect) them to the Whisker app. To sync the robots with the app, you scan a QR code that's on the machine. The Litter-Robot 3 Connect has the code in the back of the machine at the base. The Litter-Robot 4's code, on the other hand, is more conveniently positioned under the waste drawer. While this isn't a big deal for the initial setup, the positioning of the QR code makes a difference if the Litter-Robot disconnects from the app and needs to be reconnected. When I need to reconnect the Litter-Robot 3 Connect, I have to take it out of the credenza it's in and spin it around to find the QR code. With the Litter-Robot 4, I can just pull the waste drawer out and it's right there—no need to fuss with the positioning. The design is the biggest difference between the Litter-Robot 3 Connect and 4—and it's not just about the looks. The construction also factors into odor control and how many cats the Litter-Robot can accommodate. Let's start with size. The Litter-Robot 4 is narrower than the Litter-Robot 3 Connect. While they have the same height (29.5 inches) and depth (27 inches), the Litter-Robot 4 measures 22 inches wide, compared with the 24.5-inch width of the Litter-Robot 3 Connect. At the end of the day, though, both of these Litter-Robots are big. Neither one of them is going to blend in seamlessly with its surroundings, so you have to be willing to sacrifice some space regardless of which model you pick. The entryway of the Litter-Robot 4 is 15.75 inches, compared with the Litter-Robot 3 Connect's 10.25 ... More inches. That said, the Litter-Robot 4 has some design upgrades that can benefit your cat. For starters, the entryway is much wider: 15.75 inches compared with the Litter-Robot 3 Connect's 10.25 inches. While my cats never seem bothered by the smaller opening of the latter, they definitely stick out of it more when they're doing their business; they just seem more comfortable in the Litter-Robot 4. The step into the entryway is also closer to the ground on the newer model, so it can be a better option for smaller cats or senior cats with mobility issues. (Whisker does sell ramps to make the taller step on the Litter-Robot 3 Connect more manageable, but with the Litter-Robot 4, you don't need it.) Another notable difference is the waste drawer. The Litter-Robot 4's drawer has an overall smaller footprint, though the area that collects waste is larger. This means you don't have to change the trash bag as often. The Litter-Robot 4's drawer also has a more rectangular shape, so waste spreads out more evenly. With the Litter-Robot 3 Connect, I often notice that clumps pile up in the center of the drawer, sending false signals to the sensors that the waste drawer is full. That doesn't happen with the Litter-Robot 4. Additionally, the trash bag fully covers the waste drawer in the Litter-Robot 4. The Litter-Robot 3 Connect has clips inside the waste drawer to keep the trash bag in place, but if it's not secured properly, it can cave in, creating a pretty annoying mess. This ties into design, but it's worth calling out odor control separately since it's one of the most vital parts of a litter box. While both models have carbon filters that need regular replacing, the Litter-Robot 4 is much more effective at trapping odors than the Litter-Robot 3 Connect, even with a full waste bag. Whisker says this is because the waste drawer is deeper and has a tighter seal. I rarely smell any waste in the Litter-Robot 4—unless it's fresh and still in the chamber before cycling. With the Litter-Robot 3 Connect, I can tell when it's full just by the way it smells. It's not as strong as an open litter box, to be sure, but things do get musky if you don't keep up with cleaning. The safety sensors also got an upgrade in the Litter-Robot 4. The Litter-Robot 3 Connect has weight sensors inside the globe that are triggered when your cat starts to enter or is inside the machine. These sensors stop or delay a cleaning cycle to keep your cat safe.

For comparison, the minimum weight for the Litter-Robot 3 Connect is 5 pounds. These sensors are also so advanced that they can tell you which cat in a multi-cat household is using the litter box. While the scale isn't totally accurate—for example, it registers my 10-pound cat as weighing 7 pounds—it's still a useful tool for tracking the bathroom habits of each of your pets. If one of your cats isn't using the bathroom as often as they should (which can be a sign to call the vet), this feature can help alert you, says Jacob Zuppke, CEO and president of Whisker. While the scale isn't totally accurate, it's a useful tool for tracking the bathroom habits of each ... More of your pets. While the laser sensors make for a safer machine, they also make it more sensitive—I've had more accidental triggers with the Litter-Robot 4 than the Litter-Robot 3 Connect. Though those incidents can be annoying, Zuppke says the brand's engineering team is always working behind the scenes to find the right level of sensitivity for these sensors.

Meanwhile, the sensors in the Litter-Robot 4 can monitor both waste and litter levels, so you can see exactly how full the waste drawer is and whether you need to add litter to the globe. The Litter-Robot 4 has an intuitive control panel consisting of five buttons and an LED display. Noise, or lack thereof, is another major difference between these two models. The Litter-Robot 4 is significantly quieter than the 3 Connect—I can barely hear it when it's running. The Litter-Robot 3 Connect isn't obnoxiously loud, but I'd say it's at least twice as loud as the Litter-Robot 4. (The sound level is similar to an electric can opener or a bathroom fan.)

In my opinion, the upgrades are worth the higher cost, especially when you consider how long these litter boxes are meant to last. I've owned the Litter-Robot 4 for a year and a half so far, so it breaks down to an extra $8 or so each month. And if you can't swing the upfront cost, Whisker offers payment plans through Affirm. If it's within your budget, I recommend purchasing the Litter-Robot 4. While I'm happy with the performance of both machines, the newer model's design is such a massive upgrade. It's considerably better with odor control, able to hold more waste and much quieter, which I believe are worth the extra cost.

In short, yes, it's worth upgrading to the Litter-Robot 4, even though it costs $150 more than the Litter-Robot 3. With the Litter-Robot 4, you get better odor control, a bigger waste drawer and an overall smaller footprint (with a more aesthetically pleasing design). The Litter Robot 4 also has an upgraded weight sensor that makes it a better pick for multi-cat households, since you can monitor each cat's bathroom usage. Both Litter-Robot models are backed by one-year warranties, but in my experience, the lifespan is much longer. I've owned the Litter-Robot 3 Connect for four years and the Litter-Robot 4 for one and a half years, and both models are still going strong. According to Zuppke, keeping up with regular software and firmware updates through the app can help maximize the life of your Litter-Robot. Yes, the Litter-Robot 4 is quiet; in fact, I've found it to be significantly quieter than the Litter-Robot 3 Connect. When running, the latter is about as loud as an electric can opener or a bathroom fan, which may be bothersome for more skittish cats. The former, on the other hand, makes very little noise when it's cycling—I can barely hear it. Whisker recommends that you clean the Litter-Robot 4 (as well as the 3 Connect) every three months. This includes taking everything apart, thoroughly washing all the pieces and air-drying them before reassembly. You should also vacuum the area where the waste drawer sits. It takes at least an hour to clean either machine, in my experience.
