Big cats, senior cats, and multi-cat homes all share one problem: standard litter pans are too small. A cramped box leads to missed edges, scattered litter, and cats that simply refuse to use it. The eight large kitty litter boxes below solve that with wider footprints, taller walls, and easier entry, so you can match the right pan to the cat you actually have.

More Details On Our Top Picks
This is the straightforward option of the group: an open gray pan measuring 19.5 inches long by 14.8 wide, with a shallow 4.3-inch wall height. The neutral color blends into most rooms instead of shouting “cat bathroom,” which matters more than you’d think in a small apartment.
The shallow profile makes it easy for kittens and confident jumpers alike, though arthritic seniors benefit even more from a true low-entry design like the Ying Tutu later in this list.
Strong Points
- Reinforced bottom and rim resist flexing when you scoop heavy clumping litter
- Compatible with So Phresh rims and hoods sold separately, so you can add coverage later
- Lightweight plastic body is simple to carry to the sink for a deep wash
Things To Consider
- The 4.3-inch walls are short, so enthusiastic diggers may kick litter onto your floor
- Hoods and rims cost extra, which adds up beyond the base pan
Who It Suits Best
A tidy, calm single cat in a home where budget and easy cleaning matter more than containment.
Where A Sibling Pick Shines
Cats that spray or dig hard belong in the IRIS USA high-sided box, whose taller walls handle mess this pan can’t.
Where the So Phresh keeps things minimal, the IRIS USA goes tall. Its open-top design pairs with high walls that act as a scatter shield, catching litter kicked upward and spray aimed sideways. The open top also means you can check litter condition at a glance, something enclosed boxes make harder.
In a two- or three-cat home, giving each cat its own dedicated tray reduces territorial friction, and this box is built around exactly that scenario. Domestic production is a quiet plus for anyone who cares about origin.
What We Like
- Tall walls keep litter and spraying inside the tray, saving you daily floor sweeps
- Open top allows effortless monitoring of your cats’ health and litter levels
- Made in USA, which owners commonly associate with consistent plastic quality
- Spacious rectangular shape fits cats of all sizes and ages comfortably
Worth Noting
- High walls can be a climb for kittens or stiff-jointed seniors
- Black plastic shows light-colored litter dust more visibly than gray alternatives
Quick Facts
The Right Fit
Multi-cat homes with healthy adult cats that dig energetically and need their own territory.
Skip It When
Senior cats with limited mobility will find the Ying Tutu low-entry tray far kinder on aging joints.
Geriatric cats are the reason this pick exists. The 24-by-20-inch footprint gives a big cat room to turn fully around, while the low entry means no hopping over a tall lip. For a cat with arthritis, that difference decides whether the box gets used at all.
The ABS construction is worth understanding: acrylonitrile butadiene styrene is a rigid engineering plastic that resists cracking better than the polypropylene used in most budget pans. In practice, that means less flex under a heavy cat and fewer stress cracks over years of scooping.
Highlights
- Jumbo interior suits big breeds like Maine Coons as well as bunnies and small pets
- ABS body is stiffer and more durable than standard plastic trays
- Low entry removes the climbing barrier that deters older cats
- Available as a single or a two-pack for multi-cat setups
Small Caveats
- Low walls mean less protection against determined litter-kickers
- The wide footprint demands real floor space, tight in small bathrooms
Made For
Owners of senior, geriatric, or extra-large cats who prioritize accessibility over containment.
Another Choice May Suit
Younger athletic cats that spray will be better served by the MIXJOY stainless steel box and its high sides.
Plastic absorbs odor over time; steel doesn’t. That single material difference explains why metal boxes have taken over the category, and the MIXJOY leans into it with a roomy 23-by-15-by-11-inch pan sold as a pair. Two boxes side by side is the classic multi-cat arrangement vets recommend anyway.
The 11-inch walls are among the tallest here, which contains both kicked litter and urine spray. Anti-slip pads underneath keep the pan planted on tile or hardwood during vigorous digging, a detail cheaper metal boxes skip.
Upsides
- Stainless steel won’t absorb odors or stains the way plastic eventually does
- Tall 11-inch sides suit sprayers and enthusiastic diggers alike
- Two-pack covers a multi-cat home in one purchase
- Anti-slip base pads prevent sliding on smooth floors
- Scoop included, so the setup works out of the box
Points To Note
- Steel pans weigh noticeably more than plastic, complicating frequent washing
- The lid configuration may feel confining to cats that prefer open pans
Feature Snapshot
Who Should Grab It
Households with two or more large cats that need durable, odor-proof pans built to last years.
Swap It Out When
A single small cat in a compact apartment gets everything needed from the smaller KISENG open pan instead.
Not every home has floor space for a jumbo pan, and this KISENG proves steel doesn’t require a huge footprint. At roughly 17 by 13 inches with moderate walls, it slots into a bathroom corner or laundry nook where the bigger MIXJOY simply wouldn’t fit.
The trade-off is capacity. The listing is explicit that this size targets small cats, so Maine Coon owners should look elsewhere. For a petite cat, though, the smooth non-porous steel surface wipes clean fast and never holds the ammonia smell that plastic traps.
Bright Spots
- Smooth, non-porous steel prevents litter sticking and speeds cleanup
- Compact footprint fits apartments and small bathrooms
- Steel resists absorbing waste odors over long-term use
Minor Gripes
- Too small for large breeds; measure before committing
- Shallower walls offer modest scatter protection compared with the IRIS USA
At A Glance
Right Fit For
Apartment dwellers with one small cat who want steel hygiene without sacrificing floor space.
Reach For A Different Pick When
Big cats need the KISENG XL lidded model reviewed below, which scales the same material up substantially.
Covered boxes usually punish the person cleaning them: you wrestle the whole hood off every time. FURTIME flips that script with a flip-door lid, so you open the top for scooping without dismantling anything. Small design choice, big daily difference.
The three-layer detachable shell is the other standout, letting you run it fully enclosed for shy cats or semi-enclosed for airflow. Privacy matters to some cats more than others, and this is the pick for the ones that insist on it.
Plus Points
- Flip-top lid opens for cleaning without removing the entire cover
- Three-layer shell converts between enclosed and semi-enclosed modes
- Layered structure adds leak protection against urine escaping seams
- Steel construction resists the odor absorption that plagues covered plastic hoods
Softer Spots
- More parts mean more assembly than a one-piece open pan
- Enclosed mode requires diligent scooping, since odors concentrate inside
Who Will Love This
Private, skittish cats and their owners who still want quick, tool-free daily cleaning access.
Consider Something Else When
Cats that reject covers entirely will accept the open IRIS USA high-sided box far more readily.
Think of this as the KISENG open pan grown up. The interior stretches to nearly 23 by 15 inches with 10-plus-inch walls, giving a large cat genuine room to move, turn, and settle without brushing the sides. Covered but capacious is a rare combination in this category.
Like its smaller sibling, the non-porous steel shrugs off the odor absorption that ruins plastic pans within a year or two. Owners of big breeds commonly report that interior volume is the deciding spec, and this one delivers it without going jumbo-wide.
Reasons To Buy
- Roomy interior lets large cats turn around and dig comfortably
- High walls contain scatter while the lid adds privacy
- Odor-resistant steel stays fresher than traditional plastic pans
- Lid helps contain tracked litter near the entrance
Honest Caveats
- Narrower width than the Ying Tutu may cramp very broad-chested cats
- Covered design needs regular scooping to keep interior air fresh

Whose Shelf It Belongs On
Owners of one large cat who want covered privacy without sacrificing interior elbow room.
Look Elsewhere When
Maximum floor area for giant breeds points straight back to the Ying Tutu’s 24-by-20-inch open tray.
The Idymere closes the list as the accessible entry into steel. Two sizes are offered, with the larger running about 17 by 13 inches and just over five inches deep, sized honestly for kittens, seniors, and medium cats rather than giants.
The fully open design promotes air circulation, which naturally keeps ambient odor down between scoops. You may find the shallow depth limiting for a vigorous digger, but for a gentle small cat it keeps entry effortless and cleaning quick.
Standout Traits
- Open design encourages airflow and reduces lingering smells
- Two size options let you match the pan to your cat precisely
- Low-profile walls suit kittens and elderly cats
- Steel surface cleans faster and resists odor retention
Areas To Watch
- Shallow walls offer little defense against kicked litter
- Capacity suits small and medium cats only, not big breeds
Core Details
Best Suited To
First-time steel converts with kittens or calm small cats who want an affordable starting point.
Not Your Match When
Heavy diggers and sprayers need the taller containment of the MIXJOY two-pack instead.
Choosing Between These Boxes Without Regret
Match The Pan To The Cat
Start with your cat, not the product page. A senior with stiff hips needs a low entry; a sprayer needs 10-inch walls; a Maine Coon needs turning room above all else. Measure your cat nose-to-tail-base and add several inches.
Material Decides Longevity
Plastic costs less up front but absorbs ammonia odors within a couple of years, after which many cats start avoiding the box. Stainless steel wipes clean, never holds smell, and outlasts multiple plastic pans, which offsets the higher initial spend.
Covered Or Open
Covered boxes trap odor inside and demand disciplined daily scooping, but they give shy cats privacy and contain scatter. Open pans ventilate naturally and let you monitor litter habits at a glance, which matters for spotting health changes early.
Footprint Reality Check
Jumbo pans look great online and swallow small bathrooms in person. Tape out the exact dimensions on your floor before ordering, and leave clearance for comfortable human scooping access too.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The classic error is buying for the kitten and ignoring the adult cat it becomes. Another common miss: skipping the tape-measure step and discovering a 24-inch pan doesn’t fit behind the toilet. Check wall height against your cat’s mobility, not just aesthetics.
The Case For Spending Up
Higher-tier steel boxes earn their price through lifespan and hygiene. A quality stainless pan replaces two or three plastic ones, never develops embedded odor, and typically includes extras like anti-slip pads or scoops. Multi-cat homes see the payoff fastest.
Frequently Asked Questions
How big should a litter box be for a large cat?
Aim for a pan at least 1.5 times your cat’s body length, which usually means 22 inches or more for big breeds. Extra width helps large cats turn around comfortably.
Do stainless steel litter boxes really reduce odor?
Yes, because steel is non-porous and doesn’t absorb ammonia the way plastic does over time. Regular scooping still matters, but the pan itself stays neutral.
Are high-sided boxes bad for older cats?
They can be, since climbing a tall wall strains arthritic joints. Low-entry designs exist specifically for senior and geriatric cats.
How often should I replace a plastic litter box?
Most plastic pans develop absorbed odors and scratches within one to three years. Once scrubbing no longer removes the smell, replacement time has arrived.
Do covered litter boxes work for all cats?
No, some cats refuse enclosures outright and may avoid the box entirely. Offer an open alternative if your cat hesitates at a covered one.
Wrap Up
Your cat’s age, size, and personality should drive this decision more than any ranking. Seniors thrive with the Ying Tutu’s low entry, multi-cat homes get the most from the IRIS USA or the MIXJOY pair, and privacy lovers suit the FURTIME or KISENG XL. Start with the measurement, then choose the pan that fits both the cat and the corner you’ve got.
