Big cats need big bathrooms. A Maine Coon or a chunky Ragdoll crammed into a standard pan will hang over the edge, kick litter across the floor, and sometimes refuse the box entirely. That’s a problem you solve once, with the right dimensions and walls tall enough to contain an enthusiastic digger. This shortlist focuses on extra-large footprints, high sides, and materials that survive years of daily scooping, so you can match one to your cat’s size and your cleaning habits.

More Details On Our Top Picks
Starting simple makes sense here. This open gray pan measures 19.5 by 14.8 inches with a shallow 4.3-inch profile, which suits senior cats or kittens who struggle to climb high walls. The reinforced bottom and rim give the plastic extra stiffness, so it resists the flexing that cheaper pans develop after months of scooping.
The real hook is modularity. So Phresh sells matching rims and hoods separately, so you can start open and add coverage later as your cat’s habits change.
Strong Points
- Reinforced base and rim hold their shape under heavy litter loads
- Low entry height works well for older or less agile cats
- Compatible add-on rims and hoods let you upgrade without replacing the pan
- Neutral gray finish blends into most rooms instead of shouting “cat bathroom”
Things To Consider
- At 4.3 inches deep, enthusiastic kickers may still fling litter past the edge; a separate high-back mat helps
- Plastic surfaces can retain odor over time and need periodic deep washing
Who It Suits Best
Anyone wanting an affordable, sturdy starter pan for a large but calm cat, with room to grow into a hooded setup later.
A Better Fit Elsewhere
Cats that spray over the sides belong in the IRIS USA Large High Sided Cat Litter Box, whose taller walls handle scatter far better.
Where the So Phresh keeps things low, this IRIS tray goes tall. The high-sided walls act as a scatter shield, containing both kicked litter and the spray that intact males are famous for. The open top means you can check litter condition at a glance, which matters when you’re tracking health across several cats.
It’s made in the USA and sized generously enough that each cat in a multi-cat home gets a comfortable, dedicated spot. In our view, that combination of containment plus visibility is what most busy households actually need.
What We Like
- Tall walls keep litter and spray inside the tray, cutting floor cleanup dramatically
- Open-top layout lets you monitor waste output and litter levels instantly
- Roomy rectangular footprint accommodates large breeds comfortably
- Domestic manufacturing tends to mean consistent plastic quality
Worth Noting
- High sides can be a climb for arthritic seniors; pair with a low-entry option if mobility is a concern
- Being plastic, the surface may discolor with age and needs regular scrubbing
At A Glance
Made For
Homes with two or more cats, especially where one is a chronic kicker or sprayer.
Where A Sibling Pick Shines
Senior cats with stiff joints will find the low-profile So Phresh Open Cat Litter Box much easier to enter.
This is the biggest footprint on the list at 26 by 18 inches, with 12-inch walls and a lid. That interior gives even overweight cats room to roll around and reposition, something smaller pans simply can’t offer a 20-pound Maine Coon. Stainless steel, unlike plastic, doesn’t absorb urine odors or scratch into grooves that trap grime.
The trade-off shows up in weight and cost: metal costs more upfront and the box is heavier to move during full litter changes. Owners commonly report, though, that the non-stick surface makes scooping clumps noticeably easier than plastic.
Highlights
- Largest interior here, generous enough for giant breeds to turn fully
- 12-inch sides contain spray and digging without trapping the cat
- Steel surface wipes clean and won’t hold onto ammonia smells
- Included lid offers privacy while keeping dust down
Small Caveats
- Heavier than plastic, so relocating it for deep cleans takes two hands
- Higher initial cost than basic pans, though durability offsets it over years
Feature Snapshot
Right Fit For
Owners of genuinely huge cats who want a long-lasting metal box rather than another disposable plastic pan.
Skip It When
Budget-first shoppers should look at the TownTime jumbo box below, which delivers similar floor space in plastic for less.
Not everyone wants to spend metal money on a first jumbo box, and that’s where this TownTime earns its slot. You get 24.6 by 16.9 inches of floor space with nearly 13-inch walls, plus a non-slip pad underneath so the pan stays planted when your cat launches out of it. Assembly is tool-free, so it goes from carton to usable in minutes.
The anti-scatter design closes up gaps along the edges, which is often where litter escapes on cheaper high-sided pans. For most homes, that alone justifies choosing it over a generic deep tray.
Upsides
- Jumbo interior gives large cats genuine turning room
- Nearly 13-inch walls block most kicking and spraying
- Non-slip base pad keeps the box stable on hard floors
- No tools needed for assembly, so setup takes minutes
Points To Note
- Plastic construction means periodic washing to keep odors from settling in
- You may find the gray shade darker than expected next to light flooring
Who Will Love This
First-time owners of a growing kitten or newly adopted large cat who want jumbo capacity without a premium price tag.
Swap It Out When
Households tired of scrubbing plastic should step up to the KISENG stainless steel box, whose non-stick surface cleans faster.
Multi-cat homes usually need two boxes anyway, so buying them as a set makes the math friendlier. Each MIXJOY unit measures 23 by 15 inches with 11-inch sides, roomy enough for big breeds, and the steel tray shrugs off the urine soaking that ruins plastic pans. Anti-slip pads underneath keep everything steady on tile or hardwood.
A scoop comes included, which sounds minor until you realize how quickly a good metal-friendly scoop disappears in a busy house. The honest read is that per-box value here beats buying two singles.
Reasons To Buy
- Two complete boxes in one purchase, ideal for the n-plus-one rule
- Steel trays resist odor absorption and clean with a quick wipe
- 11-inch high sides contain spray from standing cats
- Anti-slip pads prevent sliding on smooth floors
- Scoop bundled in saves a separate trip
Minor Gripes
- Each box runs slightly narrower than the Pematar, so the very largest cats have less sprawl room
- Two units demand dedicated floor space in smaller apartments
Core Details
Who Should Grab It
Owners of two or three cats upgrading from plastic to metal without doubling their spending.
Consider Something Else When
Single-cat households get better use from the larger Pematar box, since they only need one premium pan.
Enclosed boxes usually punish the person cleaning them: off comes the whole hood, twice a day. FURTIME flips that script with a hinged flip-top lid, so you lift one section, scoop, and close it again without dismantling anything. The three-layer shell also detaches, letting you run it fully enclosed or semi-open depending on your cat’s preference.
That flexibility matters more than it sounds. Some cats refuse covered boxes outright, and being able to convert this one to open-air keeps it viable either way.
Bright Spots
- Flip-door lid opens for scooping without removing the entire cover
- Three-layer detachable shell converts between enclosed and semi-enclosed modes
- Layered structure helps contain leaks and tracked litter
- Steel interior stays odor-free where plastic hoods trap smells
Trade Offs
- More parts than a simple pan, so occasional reassembly and deeper cleaning take longer
- Covered designs can feel cramped for the very largest breeds; check your cat’s shoulder height against the entry
Quick Facts
Whose Shelf It Belongs On
Privacy-focused owners who want a covered box but refuse to wrestle a hood off every time they scoop.
Another Choice May Suit
Cats that hate any cover will do better in the open-top KISENG box, which skips the lid question entirely.
Compared to the FURTIME’s layered enclosure, this KISENG keeps things refreshingly straightforward: an open-top steel tub at 22.8 by 15 inches with 10.2-inch sides, plus a lid available for those who want partial cover. The open configuration is the draw. Scooping takes seconds because nothing blocks your access, and the smooth steel surface releases clumps instead of welding them to the floor of the pan.
It ships with a scoop too, and the black finish hides dust better than bare steel. For daily-use reliability, this one covers the bases.
Plus Points
- Open top makes the daily scoop fast and unobstructed
- 22.8-inch length gives big cats full freedom to turn and settle
- Steel won’t absorb smells the way plastic does over months
- Scoop included, ready on day one
Areas To Watch
- At 10.2 inches, the walls sit slightly lower than the TownTime’s, so extreme kickers may still clear them
- Open tops let more dust escape during vigorous digging sessions
Best Suited To
Busy owners doing quick daily maintenance who want metal hygiene without enclosure complexity.
Reach For A Different Pick When
Deep-burying diggers that refill half the box each session fit the Tevila’s 80L capacity better.
Closing the list is the capacity king. The Tevila spans 23.6 by 15.7 inches and stands 15.7 inches tall, with an 80-liter interior that swallows up to 40 liters of litter. That depth lets serious buriers dig, bury, and cover without hitting bottom, and it stretches the time between refills considerably.
The non-porous steel tray resists scratches and leaves no residue behind, which is why owners of determined diggers tend to favor metal at this size. One thing worth considering: filled to capacity, it gets heavy, so pick its permanent home carefully.
Standout Traits
- 80L capacity accepts up to 40L of litter for deep burying
- Extra-tall 15.7-inch profile contains even athletic diggers
- Scratch-resistant steel surface wipes clean without residue
- Enclosed design cuts down on scattered litter around the box
Honest Caveats
- A full load of litter makes the box heavy to move, so placement decisions are semi-permanent
- The tall entry may challenge senior or small-jointed cats despite the XL footprint

The Right Fit
Multi-cat homes with vigorous diggers who treat every litter box like a construction site.
Not Your Match When
Elderly cats needing a step-in entry belong in the low-sided So Phresh pan instead.
What Matters Most Before Choosing Litter Boxes For Big Cats
Interior Footprint Comes First
A large cat needs roughly one and a half times its body length in floor space to turn and dig comfortably. Anything under 20 inches long starts feeling cramped for a Maine Coon, and cramped cats look for alternatives, usually your rug. Measure your current box and your cat before ordering.
Wall Height Versus Entry Ease
Tall sides, 11 inches and up, contain spray and kicked litter beautifully. The catch is access: seniors and arthritic cats need a low entry point. Match wall height to your cat’s mobility, not just its enthusiasm for digging.
Plastic Or Stainless Steel
Plastic costs less and weighs little, but it absorbs odor and scratches over time. Steel resists smell, cleans faster, and lasts years longer, which is why most picks above lean metal. Expect to pay more upfront and replace less often.
Covered Or Open
Hoods trap dust and some cats reject them entirely, yet they contain scatter and offer privacy. Convertible designs like the FURTIME split the difference. Watch your cat’s behavior for a week before committing either way.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The classic error is sizing for today’s kitten instead of tomorrow’s adult. Another common slip: buying a covered box for a cat that has never used one, then blaming the cat when accidents follow. Check return options before committing to a style your cat hasn’t tried.
The Case For Spending Up
Higher-tier steel boxes cost more because the material itself does: non-porous, scratch-resistant, and effectively permanent. Over five years, one metal pan typically outlasts several plastic replacements while staying odor-free. Frequent scoopers recover that difference quickly.
Frequently Asked Questions
How big should a litter box be for a Maine Coon?
Aim for at least 24 inches in length so the cat can turn fully. Widths near 16 to 18 inches add comfort for broad-chested breeds.
Do big cats prefer covered or open litter boxes?
Most tolerate either, though many large cats favor open tops for headroom. Introduce covers gradually and watch for refusal behavior.
Why choose stainless steel over plastic?
Steel is non-porous, so it doesn’t absorb urine odor or stain. It also resists the scratches where bacteria and smells accumulate in plastic.
How often should I clean an extra-large litter box?
Scoop daily regardless of size, since large volumes mask waste. Full litter changes work best every two to four weeks depending on the litter type.
Can one jumbo box serve multiple cats?
Veterinary guidance generally suggests one box per cat plus one extra. A jumbo box helps, but it shouldn’t replace having multiples in multi-cat homes.
Wrap Up
Picking among these eight comes down to three questions: how big is your cat, how messy is its technique, and how much do you hate scrubbing plastic? Answer those honestly and the right box selects itself. Measure your space, match wall height to your cat’s agility, and don’t be shy about stepping up to steel. Your floors will thank you within the week.
