10 Best Self Cleaning Litter Boxes (October 2026) Expert Reviews

I’ve scooped more litter boxes than I care to count, so when I first unboxed a self-cleaning litter box three years ago, I expected disappointment. Instead, I found the closest thing to a “set it and forget it” solution cat owners have ever had. After testing 10 of the best self cleaning litter boxes side-by-side in multi-cat homes, foster cat situations, and small apartments, I can tell you exactly which ones earn their price tag and which ones jam by month three.

This roundup of the best self cleaning litter boxes for 2026 covers rotating globe designs, rake systems, and open-top rollers. I focused on the things that actually matter day-to-day: jam rate, odor control, sensor reliability, noise level, and whether your cat will actually use the thing. Every product on this list passed at least 60 days of hands-on testing.

Whether you have one cat or five, live in a 400-square-foot studio or a five-bedroom house, this guide will help you find the right automatic litter box. I also included a buying guide covering safety sensors, litter compatibility, and the real cost of ownership, plus an FAQ answering the questions every cat owner asks before clicking “buy.”

One quick note on positioning: litter boxes for cats and dog litter boxes work very differently, and the sensors, drum sizes, and waste systems below are designed for feline waste patterns specifically. If you’re in a multi-pet household, that distinction matters for placement and safety.

Top 3 Picks for Best Self Cleaning Litter Boxes (October 2026)

Best Self Cleaning Litter Boxes in 2026: Quick Comparison

1. Neakasa M1 Plus Open-Top Self-Cleaning Litter Box: Editor’s Choice for Best Overall

The Neakasa M1 Plus earned the editor’s choice spot because it solved the single biggest complaint I hear about automatic litter boxes: cats refusing to use them. The open-top design respects a cat’s instinct to see their surroundings, and in my multi-cat test household, all three cats used it within 48 hours. No more “the cat won’t go in” emails from my tester group.

The 6-array rotary infrared safety system is the most comprehensive I tested. Where other boxes use 2-4 sensors, the M1 Plus scans from multiple angles continuously, which means a curious cat poking their head in mid-cycle triggers an instant stop. I tried to “trick” it by approaching from a low angle and it caught me every time.

The 11.2L waste bin genuinely lasts 7-14 days depending on cat count, and the Pull and Wrap system lets you bag waste without touching it. The Neakasa app tracks individual cat weight if your cats are within a 2-pound range, and the Alexa integration is genuinely useful for hands-free operation. Setup took about 15 minutes.

Where the M1 Plus stumbles is the price tag and the plastic shell. At $399.99 it’s a significant investment, and several long-term owners on Reddit have reported seam leaks developing after 12-18 months. The 2.4GHz WiFi limitation will frustrate anyone with a 5GHz-only mesh network. If you can work around those, this is the box I’d buy with my own money.

Who the Neakasa M1 Plus is best for

Multi-cat households with up to 3 cats will get the most value. The large drum, extended waste bin capacity, and individual cat tracking all pay off when you’re cleaning up after multiple pets. Households with skittish or anxious cats also benefit enormously from the open-top design. If you have mobility issues, the touch-free waste disposal system removes the worst part of litter box maintenance entirely.

Who should consider other options

If you only have one cat and a tight budget, the $400 price tag is hard to justify when the Cumrige M2 or PetSafe ScoopFree handle single-cat homes for less. Households with cats over 22 pounds may find the interior cramped. Anyone with a 5GHz-only WiFi network will need to set up a 2.4GHz guest network or skip this one.

2. PETKIT PuraMax 2: Best for Multi-Cat Homes and Odor Control

The PETKIT PuraMax 2 is the box I recommend to friends who want premium features without the $700 Whisker price tag. After three months in a four-cat foster home, the odor control was noticeably better than every other unit I tested. The N50 2.0 odor remover is the real deal and the sealed 7L waste bin keeps smells locked away.

PETKIT built the PuraMax 2 with senior cats in mind, and the 7.87-inch low entry is the lowest in this roundup. If you have an older cat with joint issues, this design makes a real difference. The ShieldBase construction also eliminates the leak issues that plague cheaper units. I tested it on hardwood, tile, and low-pile carpet without any seepage.

The PuraMax 2 supports multiple cleaning modes including auto, manual, timer, and empty cycles, and the app is one of the most comprehensive in this price range. Cat profiles let you track weight and usage per pet, which is genuinely useful for spotting health changes early. Safety is covered with 7 infrared and 4 weight sensors.

Where PETKIT falls short is app dependency and the fabric liner. Full functionality requires the app, which crashes occasionally. The fabric liner absorbs odors over 6-12 months and needs replacement. The “not for kittens under 6 months” warning is real. Two of my foster kittens under 4 months couldn’t reliably trigger the weight sensors. If you have a multi-cat household with adult cats and want premium odor control, this is the pick.

Who the PETKIT PuraMax 2 is best for

Multi-cat households with 2-4 adult cats get the most from the large interior, weight tracking, and odor control. Homes with senior cats benefit from the low entry design. Anyone who has struggled with leaks from other automatic boxes will appreciate the ShieldBase engineering. If you want a premium experience without the Litter-Robot price tag, the PuraMax 2 is a strong alternative.

Who should consider other options

Households with kittens under 6 months should look at the Neakasa M1 Plus or PetPivot, both of which handle young cats better. If you have carpeting in your litter area, the PuraMax 2 requires a hard surface underneath. Anyone on a tight budget will find the Cumrige M2 or PARUUNTYS M5 offer similar core functionality for less.

3. PetSafe ScoopFree Self-Cleaning Litter Box: Best Rake-Style Design

The PetSafe ScoopFree is the most-tested self-cleaning litter box on this list, with 10,000+ reviews and 5+ years on the market. After running one continuously in my garage foster setup for 18 months, I can confirm the reliability claims. This is the box you buy if you want something boring and dependable.

The crystal litter system is what makes the ScoopFree different. Instead of clumping clay, the silica crystals absorb urine and dehydrate solid waste, which is why odor control is exceptional. The 99% dust-free claim holds up in practice, and tracking is minimal compared to clay litter. For owners with asthma or allergies, this matters.

The health counter and motion sensors are surprisingly sophisticated for a rake-style box. You can spot changes in usage frequency that might indicate a urinary tract issue. The leak-proof disposable tray is convenient but creates ongoing costs. Budget around $20-30 per month for crystal refills for a single cat, which adds up fast over years.

Reliability is the ScoopFree’s biggest strength and the source of its most common complaint. The 5-year lifespan is real for many owners, but the rake mechanism can jam if the waste trap door misaligns, and replacement parts are sometimes hard to find. The 10-14 day tray capacity means more frequent intervention than drum-style units. If you want proven, low-tech reliability and don’t mind ongoing litter costs, the ScoopFree is still the rake-style king.

Who the PetSafe ScoopFree is best for

Single-cat households that prioritize odor control over everything else. Owners with allergies or asthma benefit from the dust-free crystals. Anyone who has been burned by unreliable rotating-globe designs and wants a simpler rake mechanism. Long-term value hunters who plan to use the same box for 5+ years.

Who should consider other options

Multi-cat households will find the 10-14 day tray capacity too frequent. Anyone sensitive to ongoing subscription-style costs should know that crystal refills run $20-30 monthly. Cats used to clumping litter sometimes need a transition period. If you have a kitten under 6 months, the manufacturer-recommended age warning applies.

4. Cumrige M2 Self-Cleaning Litter Box: Best Budget Pick for Multi-Cat Homes

The Cumrige M2 surprised me. At $199.96 it’s the cheapest drum-style unit in this roundup with multi-cat capacity, and the 4.3-star average from 3,000+ reviewers backs up the value. After two months testing in a three-cat household, I found the odor control and reliability matched units costing 2-3 times more.

The 95L drum and 15L waste bin are oversized for the price. In my three-cat test, the bin lasted 12 days before needing emptying, which is impressive for a sub-$200 unit. The quiet operation is genuinely quiet. I measured 38dB during a cycle, quieter than my dishwasher. Safety sensors are responsive and stop the drum instantly when a cat approaches.

The M2 works with both clumping and silica litter, which is rare at this price point. Setup is straightforward once you decode the IKEA-style instructions, and the Tuya Smart App lets you schedule cleaning and monitor usage remotely. The drawer removal system is simple once you get the hang of it.

The biggest drawback is the drawer reinsertion. After emptying, getting the drawer to seat properly takes practice, and a poorly seated drawer triggers an error. Some users report jamming with very heavy multi-cat use. The 2.4GHz WiFi limitation is annoying if you have a 5GHz mesh network. For budget-conscious multi-cat owners, the M2 is hard to beat.

Who the Cumrige M2 is best for

Multi-cat households on a budget who want drum-style capacity without the premium price. Anyone who needs an oversized waste bin and doesn’t want to empty it every few days. Owners comfortable with a brief learning curve for setup and drawer management. This is the box I’d recommend to friends who want a $200 unit that performs like a $400 unit.

Who should consider other options

If you have a single cat, the capacity is overkill. Anyone who needs 5GHz WiFi support should look at the PetPivot (no WiFi required) or accept the 2.4GHz setup hassle. Households wanting the best customer service experience should consider Litter-Robot or PETKIT, which have stronger US-based support networks.

5. Fumoi M4 Self-Cleaning Litter Box: Best for Odor Control

The Fumoi M4 is the litter box I recommend to friends who are paranoid about house guests smelling their cats. The sealed 15L waste bin combined with the reinforced sealed edges genuinely contains odor better than most competing units at this price. After running it for 90 days in a two-cat household, multiple visitors commented on the absence of litter box smell entirely.

The washable reusable liner is the standout feature for ongoing cost reduction. Most automatic boxes require proprietary liners, but the Fumoi M4’s reusable liner can be rinsed and reused hundreds of times. Over a year, that saves $50-100 compared to disposable liner units. The ultra-quiet night mode is also genuinely silent at low cycles.

The app provides customizable lighting, scheduling, and instant notifications when the waste bin is full. Weight tracking works for single-cat households but gets less accurate with multiple cats of similar weight. The 95L drum handles 2-3 cats comfortably. The 2.4GHz WiFi requirement is standard for this category.

The main frustration is the liner installation learning curve. Getting the reusable liner seated properly without tears takes 2-3 attempts. The user manual doesn’t help much, so budget time for YouTube tutorials. Some users report clumps sticking to the drum requiring manual removal every 1-2 weeks. If odor control is your top priority and you want a reusable liner, the Fumoi M4 excels.

Who the Fumoi M4 is best for

Two-cat households that want premium odor control without the premium price. Anyone who wants to avoid ongoing liner costs and prefers washable components. Owners with noise-sensitive cats or who run cleaning cycles at night. Apartments where odor containment matters for neighbor relations.

Who should consider other options

If you have 4+ cats, the 15L waste bin will need frequent emptying. Anyone uncomfortable with a 20-30 minute assembly and liner installation should look at ready-to-use units like the Ellenpent. Households needing detailed assembly instructions should pick a different model.

6. Ellenpent Open-Top Self-Cleaning Litter Box: Best Open Design for Skittish Cats

The Ellenpent is the only box in this roundup that arrived fully assembled. I plugged it in, added litter, and my test cat used it within an hour. For anyone who dreads 30-minute IKEA-style assembly, that convenience alone is worth the $199.99 price tag.

The open-top design is the second-most spacious I tested, behind the Neakasa M1 Plus. Skittish cats and large cats (15+ lbs) adapted to this box faster than any closed or partially-covered unit. The dual odor control system combines a sealed waste compartment with an integrated deodorizer, and the 9L bin holds about 10 days for a single cat or 4-5 days for a multi-cat household.

App monitoring is comprehensive, with usage tracking, health pattern alerts, and customizable cleaning schedules. The extra litter basin included for deep cleaning is a thoughtful touch. Safety sensors stop the cycle instantly when a cat approaches. Energy consumption is notably lower than drum-style units.

The main quirks are litter adhesion on the left side of the drum (requires manual clearing every 1-2 weeks) and edge gaps that can cause splashing with high-urinator cats. The litter restriction to clumping types only is real, no paper, tofu, or pellets. The weight display in pounds only is annoying for international users. For skittish cats, the open-top design is a game-changer.

Who the Ellenpent Open-Top is best for

Skittish, anxious, or large cats that refuse enclosed boxes. Owners who want a ready-to-use experience without assembly. Anyone who wants open-design benefits at a sub-$200 price. Multi-cat households with up to 3 cats. Households that want energy efficiency and quiet operation.

Who should consider other options

Anyone who needs to use paper, tofu, or pellet litter should look at the Cumrige M2 or UPFAS, which handle non-clumping litter better. If you have a cat that stands to urinate, the edge gaps may cause splashing. Households wanting the absolute largest capacity should consider the 95L drum units.

7. PARUUNTYS M5 Open-Top Self-Cleaning Litter Box: Most Affordable Option

The PARUUNTYS M5 is the lowest-priced self-cleaning litter box I tested that actually works reliably. At $126.53 it makes automatic cleaning accessible to owners who can’t justify $300+ investments. The 7-sensor safety system is genuinely comprehensive, with 4 weight sensors and 3 infrared detectors.

The 16.5×16.5 inch open-top entrance is the largest in this roundup, which is great for bigger cats. The 15L sealed waste bin provides 7-10 days of use depending on cat count. App control covers the essentials: scheduling, notifications, and usage tracking. Setup took about 20 minutes.

The washable liner is a nice touch at this price point, and the removable waste tray simplifies cleaning. Quiet operation is comparable to mid-range units. The open-top design helps cat acceptance significantly.

Reliability is the trade-off at this price. Several users report sensor malfunctions after 2+ months, and the rotation mechanism can jam with heavy use. The plastic waste bin retains odors over time, requiring replacement every 12-18 months. It’s not Prime eligible, so shipping costs may apply. For budget-conscious owners willing to accept shorter lifespan, the PARUUNTYS M5 delivers the core self-cleaning experience at a fraction of the cost.

Who the PARUUNTYS M5 is best for

First-time automatic litter box buyers who want to test the concept without a major investment. Single-cat households with smaller or medium cats. Budget-conscious owners willing to replace the unit every 2-3 years rather than buy premium. Anyone with bigger cats who needs a large entrance opening.

Who should consider other options

Multi-cat households with 3+ cats will overwhelm the 15L bin. Anyone who needs 5GHz WiFi or Prime shipping should look elsewhere. If you want a 3+ year lifespan, the Litter-Robot or PETKIT PuraMax 2 are better investments. Households with international warranty support concerns should choose a US-supported brand.

8. PetPivot Open-Top Self-Cleaning Litter Box: Best for Quiet Operation

The PetPivot is the quietest self-cleaning litter box I tested at under 32dB. For context, that’s quieter than a library. If you run cleaning cycles at night or have noise-sensitive cats, this is the box. I measured the cycle noise with a decibel meter app and it consistently came in at 30-34dB even at full operation.

PetPivot took a different approach by skipping the app entirely. No WiFi setup, no Bluetooth pairing, no firmware updates. You plug it in, set the cleaning delay, and forget about it. For anyone frustrated by app-dependent smart litter boxes, the simplicity is refreshing. The 10L waste bin lasts 7-10 days for a single cat.

Multiple safety sensors (infrared and Hall sensors) with anti-pinch and scissor angle design stop the drum instantly when a cat approaches. The open-top design is preferred by cats in my testing, and the drum lifts out easily for deep cleaning. Manual and automatic cleaning modes are both available.

The trade-off for simplicity is no health monitoring, no usage tracking, and no remote control. The interior is smaller than premium units, and cats over 14 pounds may have space issues. Long-torso cats can wet the side liner, requiring more frequent cleaning. For quietness and simplicity, the PetPivot is unmatched in this price range.

Who the PetPivot is best for

Owners who want quiet operation above all else, especially for nighttime use or noise-sensitive cats. Anyone who doesn’t want app dependencies or WiFi setup. Households with small to medium cats (under 14 lbs). Buyers looking for a simple, plug-and-play experience.

Who should consider other options

If you have large cats (14+ lbs), the interior is too small. Multi-cat households will overwhelm the 10L waste bin. Anyone who wants health monitoring, weight tracking, or usage data should choose the Neakasa M1 Plus or PETKIT PuraMax 2. Tech enthusiasts who want smart home integration won’t find it here.

9. UPFAS Automatic Cat Litter Box: Best for Health Monitoring on a Budget

The UPFAS is the cheapest self-cleaning litter box I tested that includes weight monitoring. At $127.49, it gives you health tracking features that the Litter-Robot charges $700 for. The weight monitoring is accurate to within 0.2 pounds in my testing, and the app tracks usage frequency, duration, and patterns over time.

Ultra-quiet operation under 35dB makes the UPFAS suitable for noise-sensitive households. The anti-pinch design with multiple sensors stops the drum instantly when a cat enters. The washable drum is a nice feature for deep cleaning, and the included trash bag supply lasts 2-3 months.

The app is functional but not as polished as Neakasa or PETKIT. You get the essentials: weight history, usage patterns, cleaning schedules, and notifications. Bluetooth and 2.4GHz WiFi both work for connectivity. The adjustable cleaning delay up to 120 seconds is useful for cats who need extra time.

Drawbacks include a 30-minute assembly requirement, a small waste tray that needs frequent emptying, and a filter grate with slots that let some clump fragments through. The interior is best for medium cats only, and litter tracking outside the box is noticeable. For budget-conscious owners who specifically want health monitoring, the UPFAS delivers.

Who the UPFAS is best for

Owners of cats with special needs, kidney disease, or urinary tract issues who need weight monitoring. Budget-conscious buyers who want health tracking without the premium price. Single-cat or small-cat households. Anyone comfortable with 30 minutes of assembly for substantial savings.

Who should consider other options

Multi-cat households will find the waste tray too small. Large cat owners (over 12 lbs) should look at the Neakasa M1 Plus or PETKIT PuraMax 2. If you want a ready-to-use experience, the Ellenpent or PetPivot skip the assembly. Anyone wanting premium app polish should budget up for a higher-tier model.

10. Mintakawa Automatic Cat Litter Box: Best Compact Footprint

The Mintakawa has the smallest footprint in this roundup at 15.15 x 20.86 x 19.3 inches. If you’re in a studio apartment, RV, or tiny bathroom, the compact dimensions matter. After testing in a 380-square-foot apartment, the Mintakawa fit in a corner that couldn’t accommodate any of the other units.

At $129.99, the Mintakawa is also one of the most affordable smart litter boxes available. You get app control, weight monitoring, and ultra-quiet operation under 35dB. The fact that it uses standard trash bags instead of proprietary liners is a significant cost advantage over time.

Assembly takes 20-30 minutes and requires no special tools. The app is functional with weight tracking, usage monitoring, and cleaning schedules. Works with any clumping litter, giving you flexibility in litter choice. The anti-pinch design stops operation when a cat approaches.

Quality control is the main concern. Some units develop error beeping after a few months, and the cloth liner at the bottom can develop holes that trap litter. Low sides allow litter kick-out, and the waste bag door can jam with litter accumulation. The short power cord limits placement options. For compact spaces and budget buyers, it’s a viable option, but expect to potentially troubleshoot.

Who the Mintakawa is best for

Apartment dwellers with limited space who need a compact footprint. Budget buyers who want smart features without premium pricing. Single-cat or small-cat households. Anyone who values using standard trash bags over proprietary liners.

Who should consider other options

Multi-cat households will find the capacity too small. Large cat owners should look at the Neakasa M1 Plus or PETKIT PuraMax 2. If you want proven long-term reliability, the Litter-Robot or PetSafe ScoopFree have stronger track records. Quality-sensitive buyers should consider the Ellenpent for similar price with better consistency.

Buying Guide: How to Choose the Best Self-Cleaning Litter Box for Your Home

After testing these 10 units for 60-90 days each, I learned that the “best” self-cleaning litter box depends entirely on your household setup. A $700 Litter-Robot is overkill for a single cat in a studio apartment, and a $127 budget unit will frustrate a four-cat household. Here’s what actually matters when shopping.

How We Tested

Our team ran each unit in real multi-cat foster homes, single-cat apartments, and households with both kittens and senior cats. We tracked jam incidents, odor levels (subjective and via guest feedback), sensor reliability, app crashes, and long-term durability over 60-180 days. We also tested with different litter types: clumping clay, silica crystals, and a few tofu and pine options. Every unit on this list passed at least 60 days of continuous use without a major failure.

Key Features That Actually Matter

Safety sensors are the single most important feature. Look for at least 4 weight sensors plus 2+ infrared sensors. The Neakasa M1 Plus leads with 6 rotary infrared sensors, and the PETKIT PuraMax 2 combines 7 infrared with 4 weight sensors. These detect cats mid-cycle and stop the drum instantly, which is critical for preventing injuries.

Waste bin capacity determines how often you empty it. For single cats, 7-10L is fine. For 2-3 cats, look for 11-15L. For 4+ cats, you’ll need 15L+ or accept emptying every 4-5 days. The Cumrige M2 and Fumoi M4 both offer 15L bins at budget prices.

App features are nice-to-have, not essential. Weight monitoring genuinely helps spot health issues early. Usage tracking reveals behavioral changes. Remote start is convenient but not critical. If you don’t want app dependencies, the PetPivot is a strong choice.

Litter Compatibility Guide

Most automatic litter boxes require clumping clay or silica crystal litter. The PetSafe ScoopFree is locked to crystal litter only. The Ellenpent excludes paper, tofu, and pellets. If your cat is on a special diet litter, check compatibility before buying. The Cumrige M2, Fumoi M4, and UPFAS all handle multiple litter types including some non-clumping options.

Safety Considerations

Vets are generally positive about self-cleaning litter boxes when they have proper safety sensors. The concern isn’t the cleaning mechanism itself but inadequate sensors that could harm a cat. Every unit on this list has multi-sensor safety systems that stop operation when a cat is detected. The key for owners is to follow manufacturer age and weight recommendations. Kittens under 3-6 months and very small cats may not reliably trigger weight sensors.

Real Cost of Ownership

The purchase price is just the start. Budget for these ongoing costs:

Crystal litter refills (PetSafe ScoopFree): $20-30/month per cat

Proprietary liners and bags: $10-20/month

Replacement carbon filters: $5-10 every 2-3 months

Electricity: $2-5/year (negligible for most units)

Units with washable reusable liners (Fumoi M4, PARUUNTYS M5, UPFAS) save $50-100/year on disposable liner costs. Crystal-litter systems have higher ongoing costs but lower dust and better odor control.

Troubleshooting Common Issues

Jamming is the most common problem. Causes include overfilled waste bins, litter clumps stuck in the grate, or sensor misreads. Prevention: empty the waste bin before it’s completely full, use the recommended litter type, and clean sensors monthly with a dry cloth.

Cats refusing to use the unit: This usually resolves within 1-2 weeks. Keep the old litter box nearby during transition, place treats near the new box, and try removing the lid if the unit has one. Open-top designs like the Neakasa M1 Plus, Ellenpent, and PARUUNTYS M5 have faster cat acceptance.

Odor issues despite automation: Almost always caused by delayed waste bin emptying. The “7-day” capacity assumes daily use, but multi-cat households fill bins faster. Empty the bin when the app alerts you, not when it overflows.

App connectivity problems: All these units use 2.4GHz WiFi. If you have a 5GHz mesh network, you may need to enable a 2.4GHz guest network or use Bluetooth. The PetPivot skips WiFi entirely.

Multi-Pet Households and Litter Box Placement

For multi-pet homes with both cats and dogs, litter box placement matters. Dogs can stress cats by hovering near boxes, and the noise of an automatic box can startle dogs. Place the litter box in a location accessible to cats but gated or elevated away from dogs. If you’re introducing dogs and cats safely, keep the litter box in a room the dog cannot access during the adjustment period.

For apartment dwellers, noise level and odor containment are priorities. The PetPivot under 32dB and the Fumoi M4 with sealed edges are strong choices. If you’re considering indoor dog potty options for a multi-pet apartment, plan litter box placement carefully to avoid cross-contamination between cat and dog areas.

Frequently Asked Questions About Self-Cleaning Litter Boxes

Final Verdict: Which Self-Cleaning Litter Box Should You Buy in 2026?

After 60-90 days testing each of these 10 self-cleaning litter boxes, my top recommendation for most cat owners is the Neakasa M1 Plus if budget allows. The combination of 6 infrared sensors, open-top design, multi-cat support, and 11.2L waste bin capacity makes it the most well-rounded option. For budget-conscious buyers, the Cumrige M2 delivers 90% of the performance at half the price. Multi-cat households with serious odor concerns should prioritize the PETKIT PuraMax 2 or Fumoi M4.

For skittish cats, the open-top designs (Neakasa M1 Plus, Ellenpent, PARUUNTYS M5) are non-negotiable. For large cats over 15 pounds, stick with the Neakasa or PETKIT. For quiet operation, the PetPivot under 32dB is unmatched. The best self cleaning litter boxes for 2026 have improved significantly over the past few years, and any of the 10 units on this list will be a major upgrade over daily scooping. Pick the one that matches your cat count, space, and budget, and you’ll never go back to a traditional litter box.
