Big cats need big bathrooms. A Maine Coon or a chunky Ragdoll crammed into a standard pan will hang over the edges, track litter everywhere, and sometimes start avoiding the box altogether. That’s a problem you can fix with the right dimensions and wall height. This shortlist focuses on pans built for large frames and multi-cat homes, weighing steel versus plastic, open tops versus lids, and how each one handles daily scooping.

IRIS USA Large High Sided Cat Litter Box
Pematar Stainless Steel Cat Litter Box with Lid
TownTime Extra Large Kitty Litter Box with High Sides (Grey)
TownTime Extra Large Litter Box with High Sides Jumbo (Grey)
MIXJOY 2-Pack Stainless Steel Litter Box for Big Cats

Idymere X-Large High Sided Stainless Steel Cat Litter Box
More Details On Our Top Picks
The IRIS USA tray keeps things simple: an open-top plastic pan with tall walls that contain both kicked litter and the occasional high spray. Because there’s no lid in the way, glancing over while you pass by tells you instantly whether it needs scooping or whether your cat’s habits have changed.
In a two- or three-cat home, giving each animal its own pan reduces territorial squabbling, and this one’s rectangular shape leaves plenty of turning room for larger frames. The trade-off is material: plastic holds odor over time more than the steel options further down this list.
Strong Points
- Tall sides catch scatter and spray before it reaches your floor
- Open top means quick visual checks on litter level and your cat’s health
- Made in the USA, which some shoppers prioritize for quality consistency
- Lightweight body makes weekly full litter changes far less of a workout
Things To Consider
- Plastic surfaces can retain smells and discolor after months of use; a periodic deep scrub helps
- No lid, so determined kickers may still fling a little beyond the rim
Who It Suits Best
Households running several cats who want dedicated, easy-to-monitor pans without spending much per unit.
A Better Fit Elsewhere
Owners fighting persistent odor should look at the KISENG stainless steel box instead, since metal doesn’t absorb smell the way plastic does.
This is the biggest footprint in the roundup at 26 by 18 inches, with walls standing 12 inches high. For a Maine Coon that likes to roll around mid-business, or an overweight cat that needs genuine maneuvering space, those numbers matter more than any other spec here.
Steel construction brings two practical wins: clumps don’t weld themselves to the floor of the pan, and urine can’t soak in and linger. The included lid adds privacy for shy cats, though you’ll want to confirm your chosen corner has clearance before committing to a box this size.
Highlights
- Extra-deep interior gives large breeds room to turn and dig comfortably
- Non-sticky steel surface speeds up daily scooping noticeably
- High walls contain spray from cats who aim upward
- Lid offers cover for cats who dislike exposed bathrooms
Minor Gripes
- At these dimensions, finding a discreet spot in a small apartment takes planning
- Steel pans weigh more than plastic, so relocation isn’t effortless
Quick Facts
Made For
Owners of genuinely giant breeds, or heavier cats, who want maximum interior space above all else.
Where A Sibling Pick Shines
Apartment dwellers tight on floor space will find the Idymere’s smaller profile easier to place.
TownTime’s jumbo grey pan measures roughly 24.6 by 16.9 inches with walls near 13 inches, and it arrives ready to use with no tools required. The detail that separates it from the IRIS USA pick above is the non-slip pad bonded to the base, which keeps the box planted when a vigorous digger goes to work.
That stability matters more than most people expect. A sliding pan teaches cautious cats to distrust their bathroom spot, and repositioning drift into a corner every few days gets old fast. The anti-scatter lip runs the perimeter without gaps, containing mess along the whole rim rather than just the corners.
Bright Spots
- Bottom pad grips hard floors, stopping the slide-and-skid problem
- Nearly 13-inch walls handle enthusiastic buriers and sprayers alike
- Tool-free setup means it’s usable within minutes of unboxing
- Gapped-free scatter protection keeps surrounding floors cleaner
Softer Spots
- Plastic build means odor absorption is possible over long stretches between deep cleans
- Grey finish shows dust and tracked litter more visibly than black alternatives
Feature Snapshot
Right Fit For
Homes with tile or hardwood floors where a lightweight pan tends to travel across the room.
Swap It Out When
You need maximum length for an exceptionally large breed; the Pematar adds over an inch of extra depth.
This sibling to the previous TownTime grows slightly in every direction: 25.27 inches long, 17.83 wide, and 13.11 tall. Those fractions sound trivial until a cat stands at full stretch against a wall, at which point the tallest rim in this plastic group earns its keep.
Like its stablemate, it sets up without tools and relies on a gapless anti-scatter rim. You may find the two models nearly interchangeable in day-to-day use; the honest difference is about half an inch of height and width, plus whatever price gap exists at checkout. Choose based on current dimensions and cost rather than features.
Upsides
- Tallest walls among the plastic picks, ideal for upward sprayers
- Generous floor area accommodates big cats turning around
- Gapless rim design contains litter along the entire edge
Points To Note
- Very close in size to the other TownTime, so owning both would be redundant
- Plastic surface needs regular scrubbing to stay fresh long term

Who Will Love This
Anyone dealing with a cat that sprays high or kicks litter like it’s being paid to.
Consider Something Else When
Multi-cat homes wanting separate stations get better value from the MIXJOY two-pack coming up next.
Two lidded steel boxes in one purchase changes the math for multi-cat homes. Each measures 23 by 15 inches with 11-inch walls, slightly trimmer than the Pematar but still generous, and each ships with anti-slip pads underneath plus a scoop in the bundle.
Behaviorists generally recommend one box per cat plus one spare, and this pack gets a two-cat household most of the way there in a single order. Steel floors resist the stuck-clump problem that plagues plastic, and urine can’t seep into the material itself. The lids add privacy, though they do mean lifting one off for every scoop session.
Reasons To Buy
- Duplicate set covers the one-box-per-cat guideline affordably
- Steel won’t hold urine odor the way aged plastic does
- Scoop and grip pads included, so nothing extra to source
- 11-inch walls contain most spray without becoming climb barriers
Small Caveats
- Lids must come off for cleaning, adding a step to daily maintenance
- 15-inch width is snug for the very largest breeds compared to the Pematar
Core Details
Who Should Grab It
Two-cat households that want steel hygiene benefits without buying boxes individually.
Not Your Match When
A single-cat home only needs one pan, making the KISENG solo unit the leaner choice.
The KISENG splits the difference nicely: 22.8 by 15 inches of floor space with a 10.2-inch wall height, wrapped in smooth steel that wipes clean in seconds. An open-top configuration paired with a removable lid gives you flexibility, covered for shy cats, open when you want faster airflow and quicker checks.
Compared with the MIXJOY pair, this single box trades quantity for a slightly easier daily routine, and a scoop comes bundled. Owners commonly report that steel pans are the easiest category to keep smelling neutral, since nothing absorbs, and this one follows that pattern well.
What We Like
- Non-absorbent steel surface resists lingering odor and staining
- Convertible lid setup adapts to shy or confident cats
- Scoop included, saving a separate purchase
- Compact-enough footprint fits apartments better than the Pematar
Worth Noting
- 10.2-inch walls sit lower than others here, so extreme kickers may clear them
- Single-box count means multi-cat homes need a second purchase
Spec Overview
Whose Shelf It Belongs On
Single-cat owners, especially in smaller homes, who prioritize easy cleaning and odor control.
Reach For A Different Pick When
Your cat launches litter over walls routinely; the taller TownTime Jumbo contains that behavior better.
The Idymere closes the list with the lowest entry barrier: an open steel pan measuring 23.62 by 15.75 inches, with a shallow 5.91-inch wall. That low profile is deliberate. Senior cats and stiff-jointed medium breeds step in without hopping, which matters enormously once arthritis enters the picture.
Air moves freely through the open design, helping odors dissipate instead of pooling under a lid. The trade-off is obvious: minimal side height means scatter control depends almost entirely on your cat’s digging style. Calm, tidy cats will be fine; exuberant ones need one of the taller picks above.
Plus Points
- Low 5.91-inch entry suits older or less mobile cats
- Open steel body promotes airflow and natural odor reduction
- Spacious 23.62-inch length handles large and multiple medium cats
- Simple pan shape makes deep cleans genuinely quick
Honest Caveats
- Shallow walls offer little scatter protection for vigorous diggers
- No lid option, so privacy-seeking cats may hesitate
Feature Card
Best Suited To
Owners of senior or mobility-limited cats who need gentle access above all else.
Another Choice May Suit
Young, athletic diggers belong in the TownTime Jumbo, whose 13-inch walls actually contain the mess.
What Matters Most Before Choosing Extra-Large Litter Boxes For Big Cats
Size Beyond The Label
Measure your cat from nose to tail base, then add several inches. A box should let the animal turn fully and dig without touching walls. Manufacturers’ “extra large” claims vary widely, as this list shows: footprints range from roughly 22 to 26 inches long, and that difference decides comfort for a Maine Coon versus a regular domestic shorthair.
Wall Height And Spray Control
Tall sides, anything approaching 12 or 13 inches, contain both kicked litter and standing sprays. The compromise is entry difficulty. Older cats struggle with high rims, so match wall height to your cat’s age and agility rather than defaulting to the tallest option available.
Material: Steel Versus Plastic
Stainless steel costs more upfront but resists odor absorption, scratches less visibly, and releases clumps cleanly during scooping. Plastic stays cheaper and lighter, yet most long-term owners report replacing it sooner as smells set in. Frequent deep cleaning narrows that gap considerably.
Placement Realism
A 26-inch box plus clearance for your own scooping access needs real floor space. Sketch the spot first, including lid removal swing room where applicable, before ordering.
Key Considerations Across These Picks
Traps First Timers Fall Into
The classic error is buying for today’s kitten instead of tomorrow’s adult cat. Another common misstep: ignoring entry height for senior pets, then wondering why accidents appear elsewhere in the house. Measure the intended corner too; an oversized box wedged behind a door gets avoided entirely.
What Separates Premium From Basic
Higher-tier steel models justify their cost through longevity and hygiene. Non-sticky surfaces cut scooping time, and the material outlasts several plastic replacements. Paying up pays off most for multi-cat homes, where wear accumulates quickly and odor control becomes a daily battle.
Closing Thoughts
Big cats deserve bathrooms that fit, and every option here delivers on that promise in a different way. Match the pan to your cat’s size, age, and habits, then commit to consistent scooping, because even the best box fails without routine care. Start with the dimension that matters most for your situation and work outward from there.
