That's WIRED's advice, and it matches the vet rule of one box per cat plus one. - Fill it with the **litter your cat already uses** (if the box accepts it) and add a scoop of used litter so it smells familiar. - Start with **automatic cleaning off**, then turn it on with a long delay once your cat is using the box. Whisker says over 95% of cats acclimate, a figure it bases on return reasons. - Litter box avoidance can have medical causes. If your cat goes outside the box, strains or changes habits, **call your vet** before blaming the robot. ## Our top picks - 1![Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/_astro/whisker-litter-robot-4.CZhanV3w_12M27U.webp)Large 15.75 in entry and an app that logs visits, about $699–749[Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/)Rotating globe · 3–25 lb · up to 4 cats8.7**$$$**$PremiumPrice tier: Premium[Check price on Amazon](https://www.amazon.com/dp/B0BH6MD3DJ?tag=selfcleaninglitterboxguide.com-20) - 2![Neakasa M1 Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/_astro/neakasa-m1.BQlFduq4_Z2r5bH9.webp)Open top: Tom's Guide's cats used it most in a week, about $360–450[Neakasa M1 Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/neakasa-m1/)Open-top · 2.2–33 lb · cats: not stated8.3**$$**$$Mid-rangePrice tier: Mid-range[Check price](https://www.amazon.com/dp/B0DP8XYYKC?tag=selfcleaninglitterboxguide.com-20) - 3Budget open-top that WIRED's cats took to easily, about $250[Lesure Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/)Open-top · 3.3–18 lb · cats: not stated8.0**$**$$$BudgetPrice tier: Budget[Check price](https://www.amazon.com/dp/B0GJ5BMVFS?tag=selfcleaninglitterboxguide.com-20) ### On this page 7 sections - [Before you start: is the box right for your cat?](#before-you-start-is-the-box-right-for-your-cat) - [The step-by-step plan](#the-step-by-step-plan) - [What the numbers say about acceptance](#what-the-numbers-say-about-acceptance) - [Signs the transition isn’t working](#signs-the-transition-isnt-working) - [When to see a vet](#when-to-see-a-vet) - [Bottom line](#bottom-line) - [FAQ](#faq) ## Before you choose - [Are Self-Cleaning Litter Boxes Safe?

The n+1 Rule, With or Without an Automatic Box](https://selfcleaninglitterboxguide.com/posts/how-many-litter-boxes-per-cat/) Many cats switch to a self-cleaning litter box without much fuss. Some need patience, and rushing the switch is an easy way to end up with a cat that refuses the new box. The goal is simple: make the new box feel like the old one before it starts moving. Here’s a step-by-step plan built from WIRED’s setup advice, the American Association of Feline Practitioners’ (AAFP) litter box guidance and what makers say about their own boxes. We haven’t tested these boxes ourselves, and where a test result appears, we name the outlet. This isn’t veterinary advice. If your cat stops using its box or its habits change, talk to your vet. ## Before you start: is the box right for your cat? A cat that can’t fit or isn’t heavy enough for the sensors won’t transition well, no matter how slowly you go. Check three things first: - **Weight and age.** Most boxes have a minimum cat weight for automatic mode, usually 2.2–3.3 lb, and some a 6-month minimum age. See the [kittens guide](https://selfcleaninglitterboxguide.com/posts/best-self-cleaning-litter-box-for-kittens/) or run the [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#weight=10&age=24). - **Size.** A big cat in a small entry may refuse the box. WIRED’s 17-lb cat found the [PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) cramped but used the [Purobot Max Pro 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-max-pro-2/) easily. Add your cat’s length to the checker for a size check. - **Litter.** If your cat is attached to a litter the new box can’t use, expect a harder switch. The ScoopFree crystal boxes take only PetSafe’s crystal trays, for example. ## The step-by-step plan ### Step 1: Put the new box next to the old one WIRED’s advice is to place the new box near the old one. Your cat already goes to that spot, so you’re changing one thing at a time. Pick a spot that also works long-term. The AAFP’s client guide says to avoid busy areas. A quiet corner your cat can reach without passing a noisy appliance or another pet is ideal. Use a hard, level floor: cats.com’s tester found carpet made the [PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/)’s weight sensor inaccurate. If you later want the new box somewhere else, move it once your cat is using it reliably, not during the switch. ### Step 2: Keep the old box Don’t remove the old box on day one. WIRED says to keep it until your cat uses the new one regularly. The vet guidance points the same way. The AAFP and the MSD Veterinary Manual both recommend at least one more litter box than the number of cats. Many owners keep a manual box permanently as the “plus one,” which also covers power cuts and breakdowns. See [how many litter boxes per cat](https://selfcleaninglitterboxguide.com/posts/how-many-litter-boxes-per-cat/). ### Step 3: Use familiar litter, and add some used litter Fill the new box with the litter your cat already uses, as long as the box accepts it. Then add a scoop of used litter from the old box. WIRED says litter attractant and old litter help. Check the maker’s litter rules first. Whisker recommends clumping clay for the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) and warns that translucent or white litter can affect its level sensing. PETKIT says the Purobot Max Pro 2 needs granules under 0.5 in. Our [litter guide](https://selfcleaninglitterboxguide.com/posts/best-litter-for-self-cleaning-litter-boxes/) lists what works in each box. The AAFP’s client guide says most cats prefer soft, unscented clumping litter, and many dislike aromatic litters, deodorizers and box liners. During the switch, leave out optional scented add-ons and keep the box smelling as neutral as possible. ### Step 4: Run it with automatic cleaning off Let your cat explore and use the box before it ever moves. A cycle starting while your cat is sniffing the entry can set the whole process back. Ways to do this: - **Litter-Robot 4, 5 and EVO:** Whisker’s semi-automatic routine for small kittens is to leave the unit powered off and start cycles yourself. The same approach works for a nervous adult. - **PETKIT PuraMax 2:** the Amazon listing describes automatic, scheduled and manual modes. Use manual. - **Neakasa M1:** Kitten Mode turns automatic cleaning off. - **Others:** use the app’s off or manual setting, or unplug it, and scoop by hand. Scoop or cycle it yourself at least daily, as the AAFP recommends for any box, and only cycle when your cat is out of the room. ### Step 5: Turn on automatic cleaning, gently Once your cat is using the new box regularly, switch on automatic cleaning: - **Start with the longest delay** the app offers, so the cycle runs well after your cat has left. The [Lesure](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/) app has an adjustable delay. The [Crystal Smart](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-crystal-smart/)’s rake starts about 20 minutes after each visit. - **Use schedules or do-not-disturb.** WIRED suggests them. Avoid cycles during your cat’s usual box times, such as right after meals. - **Be home for the first few cycles.** Watch how your cat reacts to the sound and movement. ### Step 6: Retire the old box, or keep it When your cat has used the new box reliably for a while with automatic cleaning on, you can move the old box farther away or to another floor. If you have more than one cat or more than one floor, the vet rule says keep it. If you have one cat on one floor, we’d still keep a manual backup. ## What the numbers say about acceptance Whisker says over 95% of cats acclimate to the Litter-Robot 4. It bases that figure on return reasons, so treat it as the maker’s claim rather than an independent study. Independent tests show preferences vary. In Tom’s Guide’s test of four boxes, its cats used the open-top [Neakasa M1](https://selfcleaninglitterboxguide.com/litter-boxes/neakasa-m1/) 51 times in one week, the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) 30 times, and the [Leo’s Loo Too](https://selfcleaninglitterboxguide.com/litter-boxes/casa-leo-leos-loo-too/), with the smallest opening, about a third as often as the LR4. WIRED reported that its cats took to the [Lesure](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/), the [Litter-Robot EVO](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-evo/) and the [ELS PET Orbitie](https://selfcleaninglitterboxguide.com/litter-boxes/els-pet-orbitie/) quickly. The MSD Veterinary Manual notes that some cats prefer hooded boxes, and that offering different types can help. If your cat avoids hooded boxes, an open-top model may be the easier switch. [Check the Neakasa M1 price](https://www.amazon.com/dp/B0DP8XYYKC?tag=selfcleaninglitterboxguide.com-20) or the [Lesure](https://www.amazon.com/dp/B0GJ5BMVFS?tag=selfcleaninglitterboxguide.com-20). ## Signs the transition isn’t working - **Your cat only uses the old box** after a week or two of the new one sitting beside it with familiar litter. - **Your cat sniffs or enters, then leaves** without using it. The entry may be too small or the litter unfamiliar. - **Your cat bolts when a cycle starts,** or avoids the area afterward. Noise can matter: cats.com found the [Furbulous](https://selfcleaninglitterboxguide.com/litter-boxes/furbulous-self-packing/) very loud at first. - **Your cat goes beside the box,** or anywhere outside a box. ### What to try - Go back to automatic cleaning off and give it more time. - Increase the delay, or schedule cycles only for when your cat is elsewhere. - Add more used litter, and make sure the box uses the litter your cat prefers. - Check the fit. Use the [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#weight=10&age=24&length=18) with your cat’s length. - Rule out a fault. Phantom cycles and ghost-cat errors happen; see [troubleshooting](https://selfcleaninglitterboxguide.com/posts/automatic-litter-box-troubleshooting/). - Check the return window. Amazon’s Litter-Robot listing mentions a 90-day in-home trial from Whisker, and WIRED says ELS PET offers a 90-day money-back guarantee. ## When to see a vet House-soiling isn’t always about the box. The AAFP and ISFM publish guidelines to help vets diagnose house-soiling, and those guidelines look at the cat’s health and environment as well as the litter box. A cat that pees outside the box during a transition might be reacting to the new box, or it might have a medical problem that happened to start at the same time. Call your vet if your cat: - Goes outside the box, even with the old box still available - Strains, goes more or less often than usual, or you see blood - Changes its litter box habits suddenly - Seems unwell in any other way If your box has an app that logs visits or weight, those records can be useful to show your vet. Just remember that weight-based cat ID can mix up cats of similar weight, so check the data is for the right cat. ## Bottom line Put the new box beside the old one, fill it with familiar litter plus a scoop of used litter, run it with automatic cleaning off, and turn it on with a long delay once your cat is using it. Keep the old box until the new one is a habit, and keep at least one manual box for good. If your cat goes outside the box at any point, talk to your vet.

There's no fixed timeline. Some cats use a new box the first day, and WIRED's testers saw several cats take to boxes quickly. Others need longer. Keep the old box available and move to the next step only when your cat is using the new box regularly. ### Should I keep the old litter box during the transition? Yes. WIRED advises keeping the old box until your cat uses the new one regularly. Vets recommend one box per cat plus one anyway, so many owners keep a manual box permanently as a backup. ### Should I turn off the self-cleaning at first? It helps. Running the box with automatic cleaning off lets your cat get used to the shape, smell and entry without a moving part. Most boxes have a way to do this: Whisker's semi-automatic routine (power off), PETKIT's manual mode, or Neakasa's Kitten Mode. ### My cat is scared of the automatic litter box. What should I do? Go back a step. Turn automatic cleaning off, use a long delay or schedule cycles for when your cat is elsewhere, and keep the old box nearby. If your cat starts going outside any box, talk to your vet, since house-soiling can have medical causes. ### What percentage of cats use a Litter-Robot? Whisker says over 95% of cats acclimate to the Litter-Robot 4.
