Best Litter Boxes for Large Cats

Best for Large Cats

Whisker

Litter-Robot 4

$699

The Litter-Robot 4 is the box to beat and it knows it. Cleaning is close to flawless, the safety sensor stack is the most redundant in the category, and it runs quietly enough to sit in a bedroom. It is also the most expensive box here by a wide margin, and the value case only works if you keep it for years — which, given how well Whisker supports these, is a realistic assumption.

Runner-Up

CATLINK

CATLINK Ultra

$499

The Ultra is CATLINK putting a camera and a health monitor into a $499 box, which is roughly $300 less than anyone else charges for the same idea. It watches each visit, identifies individual cats, and flags things like blood or soft stools in the waste — genuinely useful if you are managing a cat with a known condition. The 13 L drawer is among the largest here and CATLINK claims a lab-verified 98.55% odour removal. The catch is the same one every camera box carries: there is a lens pointed at your floor, and the footage goes to CATLINK.

Also Great

Casa Leo

Casa Leo Leo's Loo Too

$599

Leo's Loo Too throws more hardware at odor than anything else that still takes ordinary bags — UV sterilisation, an active deodoriser and carbon filtration in one drawer. If smell is the problem you are actually trying to solve and you do not want to be locked into film cartridges, this is the most direct answer. The app is the weak link and feels a generation behind.

Neakasa

Neakasa M1 Plus

$449

The M1 Plus solves the single biggest failure mode of automatic litter boxes: cats that refuse to enter an enclosed globe. The open top means most cats accept it quickly, it is rated for cats from 3.3 lb all the way to 33 lb — the widest ceiling of any box we track — and the 11.2 L waste bin is among the largest. Neakasa has also engineered out the carbon filter entirely, sealing odour at the litter bed with a brush strip and sealing ring instead. The catch is the waste bags: they are Neakasa refill rolls, not kitchen bags.

PETKIT

PETKIT PuraMax 2

$389

The PuraMax 2 is the PETKIT worth buying for most people. It drops the camera that makes the Purobot Ultra cost $799 and keeps the things that actually matter day to day: a 76 L interior, a low entrance, weight-based cat identification feeding the same health tracking, and a sealed ShieldBase that is PETKIT’s answer to the leaking that plagues this category. At $389 list it undercuts its own sibling by more than half, and PETKIT includes two years of coverage.

Meowant

Meowant SC02

$269

The SC02 is the cheapest box in this index that still does everything the expensive ones do. A 75 L open interior, health monitoring through the app, integrated anti-pinch protection, and — the specification that actually matters to a lot of buyers — a 6.8 inch entrance, the lowest figure any manufacturer here publishes. At $269 that combination is hard to argue with. What you give up is polish and any real track record on materials.

PetSafe

PetSafe ScoopFree SmartSpin

$369

The SmartSpin is PetSafe abandoning the thing that made ScoopFree expensive to own. Where the old ScoopFree raked waste into disposable crystal trays you had to keep buying, the SmartSpin sifts clumps into a sealed drawer and works with any litter — clumping clay recommended. That single change removes the worst running cost in this category. It also tracks weight and litter habits through PetSafe’s app and handles cats up to 25 lb. The concern is reception: it sits at 3.6 stars, the lowest of anything we track.

PetPivot

PetPivot Open Top

$199

The PetPivot is the anti-smart-box. No app, no account, no subscription, no connectivity to go wrong — and the money that would have gone into a camera has gone into safety hardware instead: seven pairs of infrared sensors, a touch-sensitive pedal that halts the cycle on contact, and a mechanical limiter that physically restricts rotation. It also does something clever that expensive boxes often get wrong, holding a deliberate clumping delay before it rotates so litter has set and does not smear. The catch is size: the basin is tight, and owners with large cats say so even though PetPivot rate it to 22 lb.
