If you share your home with a Maine Coon, you already know the struggle. Standard litter boxes turn into cramped, messy disasters — your cat can barely turn around, litter scatters everywhere, and the odor lingers no matter how often you scoop. Finding a box that actually fits their size and habits feels like a never-ending hunt.
I’m Mo Mahin — the founder and writer behind Furric. I’ve spent countless hours analyzing veterinary safety standards, studying material science behind odor control, and listening to real owner feedback so you don’t have to guess what works.
After evaluating dozens of models on size, durability, and odor control, I’ve identified the best litter box for maine coon cats that actually fits their massive frame.
How To Choose The Best Litter Box For Maine Coon
Maine Coons are not average cats. They need a box that respects their size, digging style, and deep instinct to bury. Focus on these three pillars to make the right choice.
Prioritize True Floor Space
A Maine Coon needs at least 24 inches of length and 16 inches of width to stand and turn comfortably. Anything smaller forces them to crouch awkwardly, which leads to accidents outside the box. Look for dimensions that give your cat room to move without touching the walls.
Choose Stainless Steel Over Plastic
Plastic absorbs urine odors and develops microscopic scratches that trap bacteria. Stainless steel is non-porous, odor-resistant, and wipes clean in seconds. For a breed prone to deep digging and strong urine output, metal is the only material that stays fresh long-term.
Look for High Sides and Leakproof Seams
Maine Coons are enthusiastic diggers and many males spray upward. Walls of at least 10 to 12 inches prevent litter from flying out, while an overlapping or sealed base stops urine from leaking through the seams. A raised back panel also helps contain messes from cats who back up too far.

In-Depth Reviews
1. Pematar XXXL Stainless Steel (Grey)
This is the largest litter box on our list at 28 inches long and 20 inches wide, with a towering 14-inch wall height. It gives even the biggest Maine Coon enough room to stand, turn, and dig without hitting the sides. The stainless steel construction resists odors permanently, and the overlapping lid design locks urine inside so nothing seeps through the seams.
Pematar manufactures their own steel boxes, which explains the superior build quality. The non-stick bottom rinses clean with just water, and the included scoop has a handy stand for storage. Owners of 20-pound cats report that their pets finally have proper headroom and no longer kick litter onto the floor. The box also comes with a rubberized pad that catches stray granules and is simple to wipe down.
If you want a single-box solution that will last 3 to 5 years and truly fits a full-grown Maine Coon, this is the one to buy. The price reflects the premium size and material, but the durability and odor control make it a smart long-term investment.
Why we love it
- Massive interior fits even the largest Maine Coons comfortably
- Stainless steel never absorbs odors and cleans with a quick rinse
- High walls and overlapping lid prevent urine leaks and litter scatter
Good to know
- Requires a dedicated floor space of nearly 29 inches in length
- Needs a generous amount of litter to fill the deep pan properly
2. KMNSUN XXXL Stainless Steel (Navy Blue)
Coming in even slightly larger than the Pematar at 28.5 by 20.5 inches, this navy blue box offers a 60-liter capacity that can hold a full month’s worth of litter for a single large cat. The 14-inch walls are a lifesaver for owners of cats who pee standing up or dig with serious enthusiasm. The stainless steel surface is smooth, non-stick, and completely odor-resistant.
KMNSUN focused on making this box practical for multi-cat homes as well. The extra width means two cats could share comfortably in a pinch, and the deep pan reduces the frequency of full cleanouts. Owners rave about how easy it is to maintain — a simple hose-down and wipe restore it to like-new condition. The navy blue color also hides minor staining better than lighter shades.
For anyone who wants the absolute maximum floor space and a color that blends into darker rooms, this is a fantastic choice. It costs a bit more than mid-range options, but the build quality and sheer size justify every penny for households with multiple large cats.
Why we love it
- Largest dimensions on the market at nearly 29 inches long
- Ultra-smooth steel surface wipes clean effortlessly
- Deep 14-inch walls stop all litter and urine escapes
Good to know

3. Pematar XXL Stainless Steel (Dark Gray)
Pematar’s XXL model offers a slightly more compact footprint at 26 by 18 inches while still providing ample room for most Maine Coons. The 12-inch walls are tall enough to contain deep diggers, and the overlapping seam design keeps urine from leaking out the sides. As a factory-direct manufacturer, Pematar controls the quality of the steel from start to finish.
The dark gray finish looks modern and hides smudges well, making it a great fit for living areas or bedrooms. Owners mention that the stainless steel does not retain any smell even after months of use, and the non-stick bottom makes scooping a breeze. The included lid snaps on securely and prevents curious dogs from sneaking a snack.
If the largest boxes feel too big for your space but you still need premium odor control and durability, this XXL is the sweet spot. It delivers the same material quality as the XXXL models but in a size that fits more standard corners.

4. TownTime XL Litter Box (Green)
This plastic box from TownTime offers generous dimensions at 24.6 inches long and 16.9 inches wide with 13-inch high sides. It is significantly more affordable than stainless steel options while still providing enough space for a Maine Coon to move comfortably. The anti-scatter design uses a covered top and a non-slip bottom pad to keep everything in place.
Assembly is truly tool-free — the top clips onto the base in seconds. The minimalist green design looks fresh and modern, and the high sides prevent most litter from flying out even when your cat digs with abandon. Multiple owners confirm that their large cats adapted quickly and appreciated the extra headroom compared to standard covered boxes.
For budget-conscious households that still want a spacious, enclosed box, this TownTime model delivers real value. Just keep in mind that plastic will eventually absorb odors over time, so replacing it every 12 to 18 months is recommended.

- No tools needed — sets up in under a minute
- High 13-inch walls rival premium steel options
Good to know

Each box measures 24 by 16 inches with 12-inch walls, making them suitable for most Maine Coons. The enclosed design includes a buckle system that keeps the top cover securely attached even when your cat jumps on it.
Both boxes come with a scooper and a stand, plus a filter step at the entrance that catches loose litter from your cat’s paws. The dark gray and light gray colors let you place one in two different rooms or use them side by side for multi-cat homes. Owners consistently mention that the stainless steel cleans up beautifully and does not hold any smell between washes.
If you have two large cats or want a backup box without doubling your spending, this set is a smart buy. The build quality is solid, and the included accessories reduce the need for separate purchases.

6. Marchul Stainless Steel XL (Black)
Marchul’s stainless steel box is an excellent entry point for owners wanting to switch from plastic. It measures 24.4 inches long and 16.5 inches wide with 6-inch walls and a curved leakproof base that seals in urine. The complete kit includes a matching steel scoop, a scoop holder, and a dedicated litter mat — everything you need in one purchase.
The 6-inch walls are lower than other options on this list, but the curved base design minimizes splashing. Owners transitioning from standard plastic trays report a dramatic reduction in odor right away. The non-porous steel surface wipes clean easily and never develops the scratches that trap bacteria in plastic boxes.
This is a great choice for Maine Coon kittens or smaller adults who don’t need extreme wall height. The total package value is hard to beat, and the quality of the stainless steel will last for years with proper care.
Why we love it
- Complete set including mat, scoop, and holder

- Stainless steel eliminates odor on contact

7. PEDIBAT XL Stainless Steel (White)
PEDIBAT’s XL enclosed box offers a 24 by 15.5-inch footprint with 12-inch walls in a clean white finish. The stainless steel base is scratch-resistant and non-porous, while the included lid features a 30-degree inclined filter plate that knocks litter off your cat’s paws as they exit. The kit also comes with a double-layer honeycomb mat for extra tracking control.
Owners of 15-pound cats confirm the box provides plenty of room, and the high sides keep urine and litter contained. The snap-on lid stays secure during daily use, and the white color brightens up the corner where it sits. A handful of users note that the plastic guard clips could be more robust, but the steel pan itself holds up perfectly.
For those who prefer a clean, bright look and want an all-in-one kit with a lid and mat, this PEDIBAT model delivers solid mid-range performance. It works especially well for single Maine Coon households that value odor control and easy maintenance.
Why we love it
- White finish keeps the area looking fresh and clean
- Inclined filter plate reduces litter tracking significantly
- Stainless steel base resists scratches and odors
Good to know
- 15.5-inch width may be tight for very large Maine Coons
- Plastic lid clips could wear out over time
Safety & Care Tips
Choose the Right Litter Depth
Maine Coons need at least 3 to 4 inches of clumping litter to dig and bury comfortably. Too little litter encourages them to scratch the bottom, which accelerates wear on any box. Stainless steel handles this well, but with plastic boxes, deep litter helps prevent scratches that trap bacteria and odors.
Clean Stainless Steel Correctly
Avoid abrasive pads or bleach-based cleaners on stainless steel. Instead, use warm water and mild dish soap with a soft cloth. For stubborn residue, a paste of baking soda and water works wonders. Never let urine sit for days — even non-porous steel benefits from weekly deep cleaning to maintain its odor-free properties.
