Best Litter Box for Maine Coon Cats: Size Guide & Top Picks

The best litter box for a Maine Coon is an open, high-sided box at least 1.5 times your cat’s body length, which for most adults means 28 inches or longer. Maine Coons are one of the largest domestic cat breeds, and most litter boxes on store shelves simply weren’t designed with a 15–25 pound cat in mind. A box that’s too small leads to messy edges, litter tracked everywhere, and in some cases a cat who avoids the box altogether. Here’s what size to buy, which styles work, and the options worth considering at each budget.

Quick Facts

Why Standard Litter Boxes Fall Short

Most commercial litter boxes are sized for an average domestic cat in the 8–12 pound range. A full-grown Maine Coon can be double that weight and considerably longer nose to tail. In an undersized box, a Maine Coon often can’t turn around or dig properly without hanging over the edge, which is usually where “missed the box” complaints actually come from. It’s rarely a behavior problem; it’s a box that’s the wrong size for the cat.

What Size Litter Box Does a Maine Coon Need?

A good rule of thumb: the box should be at least 1.5 times the cat’s body length, measured from nose to the base of the tail, not including the tail itself. Measure your cat while they’re standing, then multiply by 1.5.

For most adult Maine Coons, that puts the practical minimum around 28–30 inches long, with many owners finding 32–36 inches more comfortable for large males. Width matters too: the cat should be able to turn a full circle without stepping on the rim.

Best Litter Box Options for Maine Coons

Here’s the honest catch with this breed: the largest plastic litter pans sold in most pet stores top out around 24–26 inches long. That’s enough for a smaller adult, but short for a big male. The options below are listed from lowest to highest cost.

Large storage tote. The cheapest option is also the roomiest. A plastic storage tote in the 100–120 quart range gives a large Maine Coon more floor space than almost any box sold as a litter box, with tall walls that contain kicked litter. Cut one short side down to about 6 inches for an entry point and sand the cut edge smooth. Tote walls taper inward, so measure the inside floor rather than trusting the label.

Extra-large high-sided pans. Pans like the Frisco High Sided Extra Large and the Petmate Giant are the biggest conventional boxes that are easy to find. Both have tall walls with a lowered entry. They suit a cat with a body length up to about 16–17 inches; beyond that, the 1.5x rule says to go bigger.

XXL stainless steel pans. Stainless steel doesn’t scratch the way plastic does, so it holds less odor over the years and wipes clean more easily. Sizes vary a lot between models, so check the interior length against your cat’s measurement before buying. Expect to pay noticeably more than for plastic.

Self-cleaning boxes. Many automatic boxes are built around an enclosed globe sized for an average cat. If you want one, compare the entry opening and interior space against your cat’s size, and check the maker’s stated weight limit, before committing.

Covered vs. Open Boxes

Covered boxes are usually a poor fit for this breed for two reasons: the domed shape restricts a large cat’s ability to fully turn and dig, and the lid traps odor inside the space the cat has to stand in. Open or high-sided boxes (sides tall enough to contain digging and kicked litter, but no lid) tend to work better. They give a Maine Coon room to move and make it easier to spot when the box needs attention.

Litter Depth and Type

Because Maine Coons tend to dig more vigorously than smaller breeds, a shallow layer of litter gets kicked out fast and exposes the bottom of the pan. Aim for 3–4 inches of litter, a little more if your cat digs down to the plastic. A clumping, low-dust formula tends to hold up best under heavier digging, and low-dust litter also clings less to a long coat.

What to Look For When Shopping

• Length of at least 28 inches, ideally 32+ for larger males
• Low-profile entry if the cat is a kitten or senior with mobility concerns
• High sides (6+ inches) to contain kicked litter without a lid
• Easy-to-clean, non-porous material, since scratched plastic can trap odor over time
• Interior measurements, not exterior, because rims and tapered walls can cost you several inches

Cleaning & Maintenance for Heavy Diggers

A bigger cat with a stronger digging habit means more litter gets displaced, more waste volume per scoop, and faster odor buildup than a standard-sized cat produces. A few adjustments make upkeep easier.

Scoop at least once a day, twice if the box gets heavy daily use, since a large-bodied cat produces more waste per visit than an average cat. A wide, long-handled scoop makes this faster in an oversized box than a standard narrow one.

Because Maine Coons tend to kick litter well past the box’s edge, a litter mat with deeper grooves (rather than a flat mat) catches more of what gets flung during digging, and cuts down on tracked litter through the house.

Full litter changes should happen roughly every 1–2 weeks with clumping litter, sooner if odor builds up faster than expected. A bigger box takes more litter to fill, so budget for more per change than a standard-size box would use.

FAQ

Do Maine Coon cats use a litter box?
Yes. Maine Coons use a litter box like any other cat and are generally easy to litter train as kittens. When an adult stops using the box, the most common cause is a box that’s too small or not clean enough. If the box is properly sized and clean and the problem continues, see your vet, since litter box avoidance can also signal a urinary or other health issue.

What size litter box does a Maine Coon need?
At least 1.5 times the cat’s body length from nose to the base of the tail. For most adult Maine Coons that works out to 28–30 inches long at minimum, and 32–36 inches for large males.

Is a storage tote actually safe to use as a litter box?
Yes, as long as it’s a sturdy general-purpose plastic tote with smooth walls and any cut edge is sanded down. Many owners use one as a permanent, low-cost solution rather than a temporary fix.

How many litter boxes should I have for one Maine Coon?
The general guideline for any cat is one box per cat plus one extra, so a single Maine Coon household typically still benefits from two boxes, especially in a multi-level home.

Do Maine Coons need a different litter box as kittens?
Yes. A jumbo adult-sized box can be too tall-sided for a young kitten to climb into comfortably. A smaller, low-entry box works better until they’re a few months old, then transition to a larger one as they grow.
