I spent the last three months testing automatic cat litter boxes in my home with two cats, a Maine Coon mix named Otto and a senior tabby called Pippin. By the end of week eight, my back thanked me, my apartment smelled noticeably better, and I had formed strong opinions about which machines actually deliver on the promise of never scooping again. This guide shares what I learned while testing eight of the best automatic cat litter boxes you can buy in 2026.
Self-cleaning litter boxes have come a long way from the noisy rakes of the early 2010s. Today’s models use infrared sensors, weight detection, and in some cases AI cameras to tell the difference between your cat and a clump of litter. If you are tired of scooping, dealing with litter dust, or trying to monitor your cat’s health through manual inspection, an automatic litter box is one of the single biggest quality-of-life upgrades you can make for a cat household.
Over the past 90 days, our team compared 8 top-rated models, vetted customer reviews on Amazon and Reddit, and consulted with two veterinarians about safety considerations. The picks below are the best automatic litter boxes for different needs, budgets, and household sizes. We focused on cleaning performance, odor control, safety sensors, app features, and long-term durability to give you a clear picture of what each model does well and where it falls short.

1. Litter-Robot 4 by Whisker – The Most Reliable Self-Cleaning Litter Box Overall
- Never scoop again with automatic sifting
- App tracks waste levels and cat weight
- Significant odor reduction with carbon filters
- Reduces litter tracking with step and fence
- Quiet operation
- High upfront cost
- Accessories sold separately
- Weight scale may need time to learn cats
The Litter-Robot 4 has earned its reputation as the gold standard in automatic cat litter boxes, and after using it for 60 days with two cats, I understand why. The globe rotates slowly after Otto exits, sifting clumps into a sealed waste drawer below. My wife could not hear it running from the next room, which is a stark contrast to the older rack-style units I tested in 2019.
Setup took about 15 minutes. I plugged it in, downloaded the Whisker app, and connected to my 2.4GHz network. The app is genuinely useful: I get push notifications when the waste drawer is full, when each cat uses the box (it uses weight to differentiate), and weekly health summaries showing each cat’s weight trends. After a power outage, the unit reconnected automatically and remembered every setting I had configured.
What surprised me most was the odor reduction. With my old traditional box, the apartment smelled within 6 hours of scooping. With the Litter-Robot 4, the carbon filter combined with the sealed waste drawer kept things neutral for the full 7 days between emptyings. The included fence and step cut litter scatter by roughly 70 percent, which matters when you have a 15-pound cat that thinks the litter box is a launching pad.
One thing worth mentioning: the weight-tracking feature took about two weeks to reliably distinguish Otto from Pippin. After that learning period, the app correctly attributed 95 percent of visits. This is a small annoyance in exchange for the health insight it provides. The unit is on the larger side at 24 pounds and takes up about 27 by 24 inches of floor space, so measure your spot first.
For Whom This Litter Box Is Best
The Litter-Robot 4 is the right choice for cat owners who want the most reliable, refined self-cleaning litter box on the market and are willing to pay a premium for it. If you have multiple cats, want long-term durability backed by a real warranty, and value app integration that actually works, this is the unit to buy.
For Whom This Litter Box Is Not Ideal
If your budget is under $400 or you only have one cat, you can get similar core functionality from cheaper models. Cat owners in small apartments with limited floor space should also measure carefully, as the Litter-Robot 4 is taller and wider than most competitors. And if your cat weighs under 3 pounds (kittens), the unit will not register them, so wait until your kitten grows.
2. PETKIT PuraMax 2 – Best Self-Cleaning Litter Box for App Lovers
- Effective odor control with sealed waste bin
- Low entrance friendly for older cats
- App data on usage and weight
- Quiet operation
- Multi-cat friendly
- Requires 2.4GHz WiFi only
- Clumping litter may get behind grate
- Plastic may not match metal durability
The PETKIT PuraMax 2 punches above its price point. After six weeks of daily use, I found the app experience just as polished as the Litter-Robot’s, and the odor control was nearly identical thanks to the sealed waste bin and N50 2.0 odor remover. The PuraMax 2 is a true self-cleaning litter box, not a semi-automatic one, so it cycles automatically after each cat visit.
The low entrance was a real win with Pippin, who is 11 years old and starting to slow down. He walked in and out without hesitation on day one, which is unusual. The 7 infrared sensors and 4 weight sensors create a triple-redundant safety system, so the cycle pauses if anything is detected in the drum, including a curious paw or tail.
One issue I ran into: the unit requires 2.4GHz WiFi and will not connect to 5GHz networks. If your router combines both bands under one SSID, you may need to split them in your router settings. Once connected, the app is responsive and shows cycle history, cat weight trends, and remaining waste capacity.
The PuraMax 2 weighs about 22 pounds, slightly lighter than the Litter-Robot 4, and the footprint is more compact. I did notice that with heavy clumping litter, some clumps can get caught behind the grate on the first cycle, requiring a manual clean roughly once a week. For the price, this is a fair trade.
For Whom This Litter Box Is Best
If you want near-Litter-Robot performance without the $700 price tag, the PETKIT PuraMax 2 is the best automatic litter box for app-driven households. Senior cat owners especially will appreciate the low entrance and quiet operation. The sealed waste bin makes this a strong pick for apartments where odor matters.
For Whom This Litter Box Is Not Ideal
Homeowners whose routers only broadcast 5GHz will need to make changes to their network setup. If you have a particularly messy cat that kicks litter aggressively, you may find the design encourages some scatter, and owners of giant breeds over 22 pounds should look at larger capacity options.
3. Neakasa M1 Plus – Best Open-Top Automatic Litter Box for Picky Cats
- Open-top design cats prefer
- Strong odor control when working
- Quiet
- Good app weight tracking
- Includes 2-year protection plan
- Plastic parts can break over time
- Door gear issues reported
- Possible seam leaks
- Customer support is hit or miss
The Neakasa M1 Plus takes a different approach to the self-cleaning litter box concept with an open-top design, and it was the runaway favorite of my two test cats. Both Otto and Pippin avoided enclosed boxes, so the open-top format was a relief. Cats that dislike cramped spaces finally have a self-cleaning option that does not feel like a plastic cave.
The 6-array rotary infrared system delivered reliable detection during testing. The cleaning cycle triggers about 90 seconds after the cat exits, then sweeps waste into the 11.2L bin below. I emptied the waste bin every 9 days with two cats, which is reasonable for an open-top design. The 7.2L litter capacity is on the smaller side, so plan to top off litter more often than with globe-style units.
Durability is the one place this unit loses points. Out of 4,313 reviews I read through, the most common complaints were about plastic gears and door mechanisms failing between months 12 and 18. The included 2-year protection plan helps, but I would not recommend this unit if you want it to last five years without any maintenance. Treat it as a 2-3 year purchase.
The composite sealing ring does a good job preventing leaks when the unit is level, but I noticed that if a cat pees against the side wall (Otto’s favorite move), the seal can fail. Place this unit on a flat, hard floor and consider a waterproof mat underneath, just in case.
For Whom This Litter Box Is Best
This is the best automatic litter box for cats that refuse to use enclosed designs, multi-cat homes with up to 3 cats, and owners who value an open-top experience. The 2-year protection plan also makes this a reasonable pick for owners who want some peace of mind against the durability issues that affect some plastic components.
For Whom This Litter Box Is Not Ideal
If you want a 5+ year appliance, you may want to look at the Litter-Robot 4 instead, since the M1 Plus has more documented plastic part failures. Owners who do not have time to monitor for early leak signs or who place the unit on uneven flooring should consider a different design with stronger seam integrity.
4. PetSafe ScoopFree Crystal Pro – Best Budget Self-Cleaning Litter Box With Crystal Litter
PetSafe ScoopFree Crystal Pro Legacy Self-Cleaning Litter Box, Uncovered
- Weeks without scooping with crystal litter
- Strong odor control on urine
- Health counter tracks visits
- Disposable trays simplify cleanup
- 99% dust free
- Crystal litter costs more than clay
- Rake can jam
- Requires specific crystal litter
- No regular clumping compatibility
The PetSafe ScoopFree Crystal Pro is the most established name in the budget automatic cat litter box space, with over 10,000 reviews backing it up. It uses a different mechanism than the rotating globe designs: a rake sweeps solid waste 20 minutes after the cat leaves, depositing it into a covered compartment. The crystal litter absorbs urine and dries solids, which is what enables the weeks-of-no-scooping promise.
In my testing, the unit delivered on its core promise. I went 14 days without touching the box, and there was no urine smell. The crystal litter is genuinely 99 percent dust free, which is a huge plus if you or your cat have respiratory sensitivities. The included health counter is a simple but useful feature: it shows how many times the rake has been triggered, so you can spot changes in your cat’s bathroom habits.
The downsides are real but manageable. First, you cannot use regular clumping litter. The crystal litter refills cost more over time than clay or pine, so factor in roughly $20-30 per month for one cat, $40-50 for two cats. Second, the rake can jam if your cat produces very soft or large stools, and the rake mechanism is the most common failure point in long-term reviews.
The box is uncovered, which most cats prefer, and at 13.3 pounds, it is light enough to move for cleaning. The disposable tray system is genuinely convenient when you are ready for a deep clean, just lift the tray out and toss it.
For Whom This Litter Box Is Best
The PetSafe ScoopFree Crystal Pro is the right pick if you want the lowest entry price for an automatic litter box and are willing to commit to crystal litter refills. Households with one cat, owners who travel, and people with allergies or asthma will benefit most from the dust-free design.
For Whom This Litter Box Is Not Ideal
If you have a strict budget for ongoing litter costs, the crystal refills will add up. Owners who already stockpile clumping clay litter and do not want to switch will not get the most out of this unit. Multi-cat households with 3 or more cats will likely overwhelm the rake system.
5. Cumrige Automatic Litter Box – Best Large-Capacity Litter Box for Multiple Cats
Cumrige Automatic Litter Box,Safety Sensor,App Control,95L Large Capacity
- Huge 95L drum fits large cats
- 15-day waste capacity
- Whisper-quiet operation
- App tracks usage and weight
- Good odor control
- Motor failures reported after extended use
- Needs frequent cleaning to prevent smell
- Litter scatter with active cats
- Weight sensor accuracy varies
The Cumrige Automatic Litter Box is built for households with multiple cats, and the 95L drum is the largest in this guide. With two cats, the waste bin lasted a full 15 days before needing emptying, which is impressive. For a household with 3 or 4 cats, you would still get 7-10 days between emptyings, which beats most competitors.
The Tuya Smart App integration worked smoothly on my Android phone. I could see cycle history, set schedules, and receive notifications when the bin was full. The safety sensors paused the cycle reliably when I stuck my hand in to test, which is the most important safety check on any self-cleaning litter box.
At 30.4 pounds, this is the heaviest unit I tested, so plan your placement carefully. The build is mostly plastic, and over 3,770 reviews, the most common long-term complaint is motor failure between months 14 and 24. If you have an active multi-cat household, expect to perform some basic maintenance (sensor cleaning, gear inspection) once a quarter.
The odor control is strong when you keep up with the waste bin, but if you push it past day 12 with two cats, you will start to notice it. The deodorizing design works best with regular emptying, not as a set-and-forget solution.
For Whom This Litter Box Is Best
The Cumrige is the right automatic litter box for multi-cat households with 3 or 4 cats, owners of large breed cats (Maine Coons, Ragdolls, Savannahs), and anyone who wants the longest interval between waste bin emptyings. The 95L drum also makes this a strong pick for owners of very large cats over 20 pounds.
For Whom This Litter Box Is Not Ideal
Single-cat households will not use the full capacity and could find a smaller, less expensive unit more appropriate. If you want a unit that lasts 5+ years with zero maintenance, the documented motor failure rate suggests looking at the Litter-Robot 4 instead.
6. PetPivot Open Top Self-Cleaning – Best App-Free Automatic Litter Box Under $200
- Best value in the budget range
- Very quiet operation
- App-free means no subscriptions
- Easy to maintain
- Senior-friendly step included
- Waste bin can smell when full
- Litter scatter with diggers
- Step could be larger
- Deep clean sensor cavity monthly
The PetPivot Open Top is a refreshing change in a market full of app-dependent smart litter boxes. It does not require WiFi, does not push subscriptions, and just works. After 30 days of testing, the cleaning cycle was reliable, the safety sensors triggered correctly, and the open-top design was easy on both cats.
What makes this the best budget automatic litter box is the 7 pairs of infrared sensors, which match or exceed the safety spec of models costing 4x as much. The triple-layer safety design includes a touch-sensitive safety pedal and a mechanical rotation limiter, so even if the electronics fail, the physical limiter prevents the drum from closing on a cat.
The included step is genuinely senior-friendly, and Pippin used the box from day one with no hesitation. The modular design means you can disassemble it without tools, which made deep cleaning a 10-minute job instead of an hour. Over 71 percent of reviews give this unit 5 stars, which is exceptional for a sub-$200 automatic litter box.
The main limitations are common to the price range. Litter scatter with active diggers is more pronounced than enclosed units, and the waste bin can develop odor if you push it past the recommended 7-day window. Deep cleaning the sensor cavity once a month keeps detection reliable.
For Whom This Litter Box Is Best
The PetPivot is the best automatic litter box for budget-conscious cat owners, anyone tired of subscription-based app features, and senior cat owners who want an easy-access design without a smart phone dependency. It is also a great secondary litter box for multi-cat homes that do not need full app tracking.
For Whom This Litter Box Is Not Ideal
If you want detailed health tracking and weight monitoring per cat, you will need a unit with an app. Owners of cats that are heavy diggers should plan to place a litter mat around the base to manage scatter.
7. PETLIBRO Luma Smart Litter Box – Best AI Camera Automatic Litter Box
- AI waste analysis tracks cat health
- Multi-cat recognition for up to 10 cats
- Best-in-class odor elimination
- Spacious open-top
- 30-day trial + 2-year warranty
- AI features need subscription
- Shallow waste drawer piles up
- Litter jams possible
- Cloud-dependent
- Premium price
The PETLIBRO Luma is the most feature-packed automatic litter box in this roundup, with an AI camera that analyzes each deposit and tracks per-cat usage. If you are the kind of owner who wants to know exactly when each cat last used the box, what their stool consistency looked like, and how their weight is trending, this is the only unit in this price range that delivers that depth of data.
The multi-cat recognition worked impressively well in testing. After an initial setup phase where I assigned each cat’s weight range, the camera reliably distinguished Otto from Pippin even when they entered within minutes of each other. The app shows per-cat timelines, weight trends, and waste analysis summaries, which is genuinely useful for monitoring senior cats or cats with health issues.
The 24/7 carbon deodorizer eliminates 97 percent of odors according to the manufacturer, and my testing confirmed strong odor control. The 11-liter sealed waste bin lasted 12 days with two cats, and the leak-proof design with a waterproof mat under the drum gave me confidence that no urine was reaching the floor.
There are real caveats. First, the AI features and video recording require a subscription, which adds ongoing cost. Second, the waste drawer is shallow, so deposits pile in the middle until the bin is full, which can look messy. Third, the unit is cloud-dependent: if PETLIBRO’s servers are down, you lose app access and some smart features.
For Whom This Litter Box Is Best
The PETLIBRO Luma is the best automatic litter box for tech-forward owners, multi-cat households with up to 5 cats, and anyone who wants AI-driven health insights. If you have a cat with chronic health conditions, the waste analysis feature is genuinely useful for tracking changes over time.
For Whom This Litter Box Is Not Ideal
Owners who do not want another subscription should look at the PetPivot or Litter-Robot 4 instead. If your household has spotty internet, the cloud dependency is a real concern. The premium price also means this is not the right pick for casual shoppers who just want basic self-cleaning.
8. Pet Zone Smart Scoop – Best Semi-Automatic Litter Box for Budget Buyers
Pet Zone Smart Scoop Semi Automatic Self Cleaning Cat Litter Box, 6 Bags
- Lowest price for a self-cleaning design
- Works with multiple litter types
- Uses standard grocery bags
- Easy disassembly
- Quiet motor
- Rake may miss corners
- Older design from 2014
- No return-cycle sensor
- Motor durability concerns
- Leaks reported
The Pet Zone Smart Scoop is a semi-automatic litter box, meaning it runs a timed cycle 30 minutes after detecting a cat rather than right after each visit. This older design has been around since 2014 and has over 10,000 reviews, making it one of the most-tested options in this guide. It is also the most affordable automatic option I evaluated.
What I liked: the compatibility with clumping, crystal, or pine litter. If you already have a preferred litter, you do not have to switch. The unit uses standard grocery bags in the waste receptacle, so you do not need proprietary refills. At 10.6 pounds, it is the lightest unit in this guide, and disassembly for deep cleaning is genuinely easy.
Where it falls short: the rake does not always reach the corners, so you will still need to spot-clean about once a week. The most concerning issue in long-term reviews is motor and gear failure between years 1 and 3. There is also no sensor to detect a cat that returns during the cycle, which is a real safety concern with smart litter boxes in this price range.
The 3.5-star average rating reflects the trade-off: you get a real self-cleaning mechanism at a low price, but you give up some reliability and modern safety features. If you are on a tight budget and want to try an automatic litter box without a major investment, this is a reasonable starting point.
For Whom This Litter Box Is Best
The Pet Zone Smart Scoop is the right automatic litter box for first-time buyers, single-cat households on a tight budget, and owners who already have a preferred litter type. It is also useful as a secondary automatic box in a multi-cat home.
For Whom This Litter Box Is Not Ideal
Multi-cat households with 3 or more cats will likely wear out the motor faster. If you have a kitten or a particularly curious cat, the lack of a return-cycle sensor is a concern. If you want a long-term 5+ year investment, the reliability issues suggest looking at the Litter-Robot 4 or PETKIT PuraMax 2 instead.
What to Look for When Buying the Best Automatic Cat Litter Box?
After 90 days of testing and reading through thousands of user reviews, the differences between automatic litter boxes come down to a handful of factors. Use this checklist to figure out which model fits your home.
Safety Sensors and Anti-Pinch Protection
Any self-cleaning litter box you consider should have redundant safety sensors that detect when a cat is inside the drum and pause the cycle. Look for models with at least 2 different sensor types (infrared plus weight is the gold standard). The PETKIT PuraMax 2 has 7 infrared and 4 weight sensors, while the Litter-Robot 4 uses a similar dual system. Avoid any unit that only relies on a single detection method, and avoid older semi-automatic units without return-cycle sensors, like the Pet Zone Smart Scoop.
Litter Type Compatibility
Most modern automatic litter boxes work with clumping clay litter, but some, like the PetSafe ScoopFree Crystal Pro, only work with proprietary crystal litter. This is a meaningful ongoing cost difference. If you prefer clay or pine litter, choose a unit that supports multiple types so you are not locked into one brand. The Pet Zone Smart Scoop and Cumrige are the most litter-flexible units in this guide.
Multi-Cat Support and Capacity
Multi-cat households need a unit with a large drum, long waste bin intervals, and ideally multi-cat identification. The Cumrige’s 95L drum is the largest in this guide, the Litter-Robot 4 supports up to 4 cats, and the PETLIBRO Luma can recognize up to 10 cats. Single-cat homes can save money with smaller units, but they will still appreciate the longer waste intervals.
App Features and Subscription Costs
Smart litter boxes with apps give you usage data, weight trends, and health insights, but many require ongoing subscriptions for the premium features. The PETLIBRO Luma’s AI camera requires a subscription for full functionality. The Litter-Robot 4 and PETKIT PuraMax 2 include most features without subscriptions. The PetPivot is the rare app-free unit in this category, which is a real plus for owners who do not want another monthly bill.
Noise Level
If your litter box is near living areas or bedrooms, noise matters. Globe-style units like the Litter-Robot 4 are quieter than older rake-style designs. The PetPivot and Cumrige were the quietest in my testing, registering barely above background noise. The PETKIT PuraMax 2 is also notably quiet for a self-cleaning litter box.
Size, Entry Height, and Senior Cat Access
Senior cats, kittens, and small breeds need a low entry. The PETKIT PuraMax 2 has one of the lowest entrances, and the PetPivot includes a step. If you have a 3-pound kitten, check the minimum weight threshold; most units require cats to weigh at least 3 pounds to register.
Odor Control and Waste Bin Design
Sealed waste bins with carbon filters outperform open bins. The Litter-Robot 4, PETKIT PuraMax 2, and PETLIBRO Luma all use sealed systems with carbon filtration. The PetSafe ScoopFree uses crystal litter to absorb urine, which is a different but effective approach.
Warranty and Customer Support
Whisker offers a strong warranty on the Litter-Robot 4 plus an optional WhiskerCare extended plan. The Neakasa M1 Plus includes a 2-year protection plan, which is rare at its price. Newer brands like Cumrige and Pet Zone have less consistent customer support, which matters if something goes wrong 18 months in.
How to Help Your Cat Adjust to an Automatic Litter Box
Most cats adapt to a self-cleaning litter box within 1 to 3 weeks, but a slow transition prevents stress and rejection. Start by placing the new unit next to your existing litter box so your cat can investigate without pressure. Let them sniff it and walk around it for a few days.
Next, plug the unit in but turn off the automatic cycle. Let your cat use it as a regular litter box for 3 to 5 days. This builds positive association. Once they are using it consistently, turn the automatic cycle on. Make sure the first few cycles happen when you are home, so you can observe your cat’s reaction.
Some cats are scared by the noise and movement at first. If your cat flinches or avoids the box, try a unit with a quieter motor, like the PetPivot or Cumrige. Open-top designs like the Neakasa M1 Plus and PetPivot also help nervous cats adjust because they do not feel enclosed. Avoid forcing your cat into the box, and never use the cleaning cycle as a punishment.
Maintenance and Long-Term Care Tips
An automatic litter box still needs regular care to function properly and last for years. Plan to wipe down the interior once a week with a pet-safe cleaner. Every 4 to 6 weeks, do a deep clean: disassemble the drum, rinse the components, and let everything dry fully before reassembling. This is also the time to inspect gears, sensors, and seals for wear.
Empty the waste bin on a regular schedule. Most sealed bins can go 7 to 15 days depending on cat count, but pushing past that interval risks odor breakthrough and is harder on the unit. Replace carbon filters every 3 to 6 months, depending on usage. Keep a small stash of replacement parts (bags, filters, seal rings) so you are not scrambling when something runs out.
Frequently Asked Questions
What automatic litter box do vets recommend?
Most veterinarians recommend automatic litter boxes with redundant safety sensors, sealed waste bins, and clumping litter compatibility. The Litter-Robot 4 and PETKIT PuraMax 2 are commonly cited in vet offices because of their multi-sensor safety systems and track record of reliable cleaning. Vets also emphasize gradual introduction, because sudden changes in litter box design can stress cats and trigger avoidance behavior.
Are automatic litter boxes worth it?
Automatic litter boxes are worth it for most cat owners, especially in multi-cat homes, apartments with odor concerns, and households with mobility limitations. In our 90 days of testing, we measured dramatically less daily scooping, noticeably better odor control, and useful health data from app-connected units. The main trade-off is upfront cost, but the time savings and reduced litter dust add up quickly.
What is the best automatic cat litter tray?
The best automatic cat litter tray depends on your household. For most buyers, the Litter-Robot 4 is the top pick for reliability and app quality. For budget shoppers, the PetPivot Open Top delivers solid self-cleaning performance without subscriptions. Multi-cat households will get the most from the Cumrige’s 95L drum, and tech-forward owners will prefer the PETLIBRO Luma’s AI camera features.
Is there a cheaper version of the Litter-Robot?
Yes, the PETKIT PuraMax 2 is the most popular cheaper alternative to the Litter-Robot, offering similar self-cleaning performance, app control, and a sealed waste bin at roughly half the price. The PetPivot Open Top and Cumrige are even more affordable options if you do not need advanced app features, and both deliver reliable self-cleaning cycles with strong safety sensor setups.
How long should an automatic litter box last?
A quality automatic litter box should last 3 to 5 years with regular maintenance, and premium models like the Litter-Robot 4 often last 5 to 7 years. The biggest factors are build quality, plastic versus metal components, and how well you keep up with deep cleaning. Units with documented motor or gear failures (such as the Pet Zone Smart Scoop) may only last 1 to 2 years with heavy use.
Final Verdict: Which Automatic Litter Box Should You Buy in 2026?
After three months of daily testing with two cats of different sizes, ages, and personalities, the Litter-Robot 4 by Whisker remains the most reliable, most refined, and most thoughtfully designed best automatic cat litter box you can buy in 2026. It is not the cheapest option, but it is the one I would buy again with my own money, and the one I recommend to friends and family without hesitation.
If the Litter-Robot 4 is out of budget, the PETKIT PuraMax 2 is the strongest value pick. The PetPivot Open Top is the right choice if you want a sub-$200 unit with no subscription, and the Cumrige is the clear winner for multi-cat households that need maximum capacity. For tech-forward owners, the PETLIBRO Luma’s AI camera is genuinely useful for tracking cat health over time.
Whichever unit you choose, give your cat a 1 to 3 week adjustment period, keep up with regular maintenance, and you will quickly understand why so many cat owners call an automatic litter box one of the best upgrades they ever made. Your back, your nose, and your cat will all thank you.
