Best Litter Box for Maine Coons in 2025
The short answer: Maine Coons need an XL litter box with high sides, a wide opening, and a non-porous surface that won't trap odor. The Huckwell Halo XL checks every box, built from 304 food-grade stainless steel with a round design that gives large breed cats the room they actually need.
Maine Coons are one of the largest domestic cat breeds in the world, regularly reaching 15 to 25 lbs and measuring over 3 feet from nose to tail. They're gentle, sociable, and endlessly entertaining. But they have one problem most owners don't anticipate until it's too late.
Standard litter boxes are not built for them.
The average litter box on the market measures around 18 x 15 inches. A full-grown Maine Coon can barely turn around in that space, let alone dig and cover comfortably. The result is litter everywhere, a cat that avoids the box, and a smell that no amount of scooping seems to fix.
If you own a Maine Coon, this guide covers exactly what to look for in a litter box and why getting it right matters more than most owners realize.
What Makes a Good Litter Box for a Maine Coon?
Size: Bigger Than You Think
The rule of thumb for litter box sizing is 1.5x the length of your cat from nose to tail base. For an average Maine Coon measuring 18 to 24 inches in body length, that means you need a litter box with at least 27 to 36 inches of usable interior space.
Most "large" litter boxes on the market measure 22 to 24 inches on the outside. Once you account for walls and structure, the usable interior is significantly smaller. Look for a box specifically marketed as XL or designed for large breed cats, and always check the interior dimensions, not the exterior ones.
High Sides: Essential for Maine Coons
Maine Coons dig. Hard. Their size means they generate more litter scatter than smaller breeds, and without high sides that litter ends up on your floor, in corners, and tracked through your home.
Look for sides at least 8 to 10 inches high. The Huckwell Halo XL features deep walls specifically designed to contain scatter from larger, more active cats.
Material: Why Plastic Is the Wrong Choice for Large Cats
This is where most Maine Coon owners get it wrong. Plastic litter boxes scratch easily, and those scratches are where bacteria, ammonia, and odor permanently embed themselves. The bigger the cat, the more force they use when digging, and the faster plastic degrades.
A Maine Coon will scratch through a plastic litter box's surface within months. Once that surface is compromised, no amount of cleaning removes the smell. You replace the box, repeat the cycle, and wonder why your house always has that faint cat smell.
304 food-grade stainless steel doesn't scratch in the same way. It doesn't absorb odor. It doesn't harbour bacteria in surface damage. It wipes clean completely every time, which for a high-traffic Maine Coon litter box makes an enormous practical difference.

Shape: Round Beats Square for Large Cats
Cats circle before they go. It's instinct. In a square box, a Maine Coon is constantly hitting corners, which feels unnatural, cramped, and discouraging for a cat that size.
A round litter box eliminates corners entirely. More usable turning space, no dead zones where waste collects, and a more natural experience for your cat. Most Maine Coons adapt to round litter boxes within 1 to 2 days.

The Huckwell Halo XL: Built for Maine Coons
The Halo XL was designed with large breed cats specifically in mind. Here's how it addresses every sizing and material issue Maine Coon owners face:
- XL interior dimensions — enough room for a full-grown Maine Coon to circle, dig, and cover without feeling restricted
- Deep high sides — contain scatter from even the most enthusiastic diggers
- 304 food-grade stainless steel — non-porous, odor-resistant, and built to last a decade or more
- Round design — mirrors natural feline movement with no corners for waste to collect
- Heavy base — doesn't slide or tip when a large cat enters and exits
- Includes a wood and stainless steel scoop — designed to match the box, not an afterthought
Available in Onyx (matte black exterior) and Arctic (light finish), both designed to belong in your home rather than being hidden away.

Other Large Breed Cats That Benefit from an XL Box
Maine Coons get the most attention but they're not the only breed that outgrows standard litter boxes. If you own any of the following, everything in this guide applies:
- Ragdoll — typically 10 to 20 lbs, one of the most commonly undersized-boxed breeds
- Norwegian Forest Cat — similar in size to Maine Coons and equally active diggers
- Siberian — muscular build requires more turning space than their weight suggests
- Savannah — long and lean, needs length more than anything else
- Bengal — not always large but extremely active, so high walls are essential

Frequently Asked Questions
What size litter box does a Maine Coon need?
Maine Coons need a litter box with an interior of at least 24 inches in its longest dimension, though larger is always better. Look for boxes specifically marketed as XL or designed for large breed cats and always check interior rather than exterior measurements.
How many litter boxes does a Maine Coon need?
The standard rule is one litter box per cat plus one extra. For a single Maine Coon, two litter boxes is ideal. For multiple cats including a Maine Coon, scale accordingly and ensure at least one box is XL sized.
Do Maine Coons need a covered litter box?
Maine Coons generally do better in open or semi-covered boxes due to their size. Fully enclosed boxes are often too small for a full-grown Maine Coon to use comfortably, and the restricted airflow can make odor worse. The Halo's optional precision-fit lid provides some coverage without fully enclosing the space.
Why does my Maine Coon keep missing the litter box?
The most common cause is a box that's too small. When a Maine Coon can't fully turn around and position themselves correctly, they end up going over the edge. Upgrading to an XL box with high sides typically solves this immediately.
Is stainless steel safe for Maine Coons?
Yes. 304-grade stainless steel is food-grade and completely non-toxic, the same standard used in pet food bowls and surgical tools. It contains no BPA, microplastics, or chemical coatings. It's significantly safer than plastic, which can leach chemicals and harbour bacteria in surface scratches.
How often should I clean a Maine Coon's litter box?
Scoop daily. Maine Coons produce more waste than smaller breeds and a dirty box leads to avoidance behaviour. Deep clean weekly. With a stainless steel box like the Halo XL, deep cleaning takes under two minutes because nothing adheres to the non-porous surface.
