Litter box problems are the number one reason cats are surrendered to shelters. Most of these problems are entirely preventable — and with Maine Coons, the most common cause is simply that the litter box is too small, too dirty, or in the wrong place.

Maine Coons are clean, fastidious cats with strong preferences. Get the litter box setup right from the beginning and you will likely never have a problem. Get it wrong and you will spend a lot of time cleaning your floors.

Size: The Most Important Factor for Maine Coons

Standard cat litter boxes are designed for average-sized cats — roughly 8–10 pounds. A fully grown Maine Coon male can weigh 20+ pounds and measure 30+ inches from nose to tail base. A standard litter box is not just uncomfortable for a Maine Coon — it is genuinely too small to use properly.

The rule of thumb for litter box size is that the box should be at least 1.5 times the length of the cat. For a large Maine Coon, that means a box at least 24–30 inches long. Standard cat boxes are typically 18 inches long. You can see the problem.

The best solution: a 40-gallon storage tote. A large Rubbermaid or Sterilite storage tote (roughly 24 x 18 x 16 inches) makes an ideal Maine Coon litter box. Cut a U-shaped entry on one of the short ends, leaving a 4–5 inch lip at the bottom to contain litter. Sand the cut edge smooth. Total cost: about $8–12. It is larger than any commercial litter box, easy to clean, and your Maine Coon will actually fit in it.

For kittens, start with a smaller box with lower sides so they can easily climb in. Switch to the larger tote as they grow — typically by 4–6 months.

How Many Litter Boxes Do You Need?

The standard recommendation is one litter box per cat, plus one extra. For a single Maine Coon, that means two boxes. For two Maine Coons, three boxes.

This is not just a guideline — it is important. Maine Coons prefer to urinate in one box and defecate in another. Having two boxes accommodates this preference and reduces the chance of a box being "too dirty" to use. A Maine Coon that considers their box unacceptable will find an alternative, and you will not enjoy their choice.

Litter: What Works and What Does Not

Unscented clumping litter: This is the gold standard for most cats, including Maine Coons. It clumps firmly for easy scooping, controls odor effectively, and does not irritate the respiratory system. We use and recommend Dr. Elsey's Ultra or Arm and Hammer Clump and Seal Unscented.

Avoid scented litters: Scented litters are designed to appeal to humans, not cats. Cats have a sense of smell roughly 14 times more powerful than ours. What smells pleasantly floral to you smells overwhelming to your cat. Many cats will avoid a scented litter box entirely.

Avoid crystal/silica litters for kittens: Crystal litters are not safe for kittens who may ingest them while grooming their paws. They are fine for adults but skip them until your kitten is at least 6 months old.

Avoid wood pellet litters for Maine Coons: Wood pellets do not clump, which means you cannot easily tell when the box needs cleaning. Maine Coons are clean cats and will protest a box that does not meet their standards.

Litter depth: Maine Coons are enthusiastic diggers. Fill the box with at least 3–4 inches of litter. Less than that and they will dig down to the bottom of the box, which they find unacceptable.

Placement: Where to Put the Litter Box

Location matters more than most people realize. A litter box in the wrong place will be avoided even if everything else is perfect.

Quiet, low-traffic areas: Cats need to feel safe and undisturbed while using the litter box. A box in a busy hallway, next to a loud appliance, or in a high-traffic area will be avoided. A quiet corner of a bedroom, bathroom, or laundry room is ideal.

Away from food and water: Cats instinctively avoid eliminating near their food source. Keep the litter box in a different room or at least on the opposite side of the room from food and water bowls.

Accessible at all times: Never put the litter box behind a closed door. Your cat needs 24/7 access. If the box is in a room that is sometimes closed, install a cat door.

Multiple floors: If you have a multi-story home, put at least one litter box on each floor. A Maine Coon should never have to travel more than one floor to reach a litter box.

Not in the basement: Many people put litter boxes in the basement to keep them out of sight. This works for some cats, but many cats — especially kittens and seniors — will avoid a box that requires navigating stairs. If you must use the basement, make sure the stairs are safe and accessible.

Covered vs. Uncovered Boxes

This is a matter of individual preference — both the cat's and the owner's. Covered boxes contain odor and litter scatter better, which owners appreciate. But many cats dislike covered boxes because odors concentrate inside, there is only one exit (which can feel like a trap), and the interior can be too small for a large Maine Coon.

If you use a covered box, make sure it is large enough for your Maine Coon to turn around comfortably inside. The storage tote approach works well with a lid — just cut a large entry hole in the lid instead of the side for a top-entry box, which also dramatically reduces litter scatter.

When in doubt, start with an uncovered box. If your cat is using it consistently, you can experiment with a covered version later.

Cleaning: The Most Important Maintenance Task

Maine Coons are clean cats with high standards. A dirty litter box is the most common cause of litter box avoidance.

Scoop at least once daily. Twice daily is better, especially in a multi-cat household. Maine Coons will protest a box that has not been scooped — and their protest will involve your floor.

Full litter change weekly. Even with daily scooping, litter absorbs odors over time. Dump the entire box, wash it with mild soap and water (avoid bleach or strong-smelling cleaners — the residual scent can deter cats), dry it completely, and refill with fresh litter once a week.

Replace the box annually. Plastic absorbs odors over time, even with regular cleaning. Replace the litter box (or storage tote) once a year.

Solving Common Litter Box Problems

Going Outside the Box

If your Maine Coon starts eliminating outside the litter box, the first step is a vet visit — not a behavior intervention. Urinary tract infections, kidney disease, diabetes, and arthritis can all cause litter box avoidance. Rule out medical causes before assuming it is a behavior problem.

If medical causes are ruled out, work through this checklist: Is the box clean enough? Is it large enough? Is it in a good location? Is the litter type acceptable? Is there a new stressor in the environment (new pet, new baby, construction noise)?

Litter Scatter

Maine Coons are enthusiastic diggers and will fling litter with impressive force. Solutions: use a box with higher sides (the storage tote approach), place a large litter mat outside the entry, or switch to a top-entry box. A top-entry storage tote is the most effective solution for litter scatter.

Tracking Litter Through the House

Maine Coons have large, tufted paws that collect litter like velcro. A large, textured litter mat placed outside the box catches most of it. Trimming the fur between the toes (the toe tufts) also helps significantly.

Refusing a New Litter

If you need to change litter brands, do it gradually. Mix 25% new litter with 75% old litter for a week, then 50/50 for a week, then 75% new for a week, then fully transition. Sudden litter changes are a common cause of temporary litter box avoidance.

The Bottom Line

Litter box success with a Maine Coon comes down to three things: big enough box, clean enough box, right location. Get those three things right and you will almost certainly never have a problem. The storage tote trick alone solves the most common Maine Coon litter box complaint — and it costs less than a bag of litter.
