The best litter box for Maine Coon cats is one your cat can walk into, turn around in and dig in without hanging over the edge. Maine Coons are a large domestic breed, so the word “large” in a product name doesn’t tell you whether the usable floor space will fit your cat.
Measure your cat from nose to base of tail, then shop by the box’s floor size and wall height, not the size name. The picks below were chosen because Maine Coon or big-cat owners report a good fit in their reviews.
For the full sizing math and a list ranked by footprint, see our guide to the best extra large litter box for big cats.
Quick Picks
Stainless High-Wall Pick: KITCATY XXL with Lid
Wide Plastic Pick: IRIS USA High Walls with Handles
Steel Corner Pick: Gimars XXXL Corner
Top-Entry Pick: WoofiGo Large Top Entry
Covered Odor-Unit Pick: LEMPISH Covered Box
Low-Entry Pick: KittyGoHere
What a Maine Coon Litter Box Needs
Floor size comes first. Your cat needs enough usable space to enter, turn and dig without crowding the walls. Check the pan or interior dimensions when they’re available, not just the size name.
Walls that match the cat. Tall walls matter if your cat kicks hard or pees high. If your cat squats low and digs gently, a lower box with more floor space can be the better choice.
The right entry. A front opening in a tall box gives easy access with containment. Top entry suits agile cats only. A low entry suits cats that step in rather than hop.
Coat. A long coat can pick up litter. Our guide to the best litter box for long-haired cats covers exit steps and lids that catch it.

KITCATY XXL Extra Large Litter Box with Lid
Why It Stands Out
The 12-inch walls overlap the steel pan and buckle on, which targets urine leaking at the seam. Many reviewers say the high sides stopped wall spray outside the box. Reviewers report it fits multiple Maine Coons and an 18 lb cat. It comes with a scoop, mat and step pedal.
Possible Downsides
At 28 x 20 inches, it needs a lot of floor space. Its enclosure also makes it a different setup from a simple open pan. Our covered litter box picks cover how hood designs compare.
Best For
Maine Coons that pee high or dig hard, in homes that want a steel pan.
IRIS USA Cat Litter Box with High Walls and Handles
Why It Stands Out
It’s an open box at 30 x 20 x 14 inches. One big-cat owner says it’s wider than most boxes sold as XXL, giving her cat room to turn and dig. Several reviewers say the high back walls hold in digging and spraying. Built-in handles make a big box easier to lift and dump.
Possible Downsides
At 30 x 20 inches, it has one of the largest footprints here, so measure the placement area first.
Best For
Maine Coons that need width more than a lid.
Gimars XXXL Stainless Steel Corner Litter Box with Lid
Why It Stands Out
It’s a triangle-shaped steel box built to sit in a room corner. The listing describes three setups: fully enclosed, semi-enclosed or open pan. One reviewer with several large cats says the high walls contain urine overspray. Many reviewers call the pan spacious for large cats.
Possible Downsides
A corner shape only fits well in a corner. Against a flat wall, it wastes floor space. Check the listing’s dimensions against your corner and your cat.
Best For
Maine Coon homes that want a large steel box designed to use a room corner.
WoofiGo Large Top Entry Litter Box for Big Cats
Why It Stands Out
The box is about 15 inches high overall, at 23.5 x 16 inches. Reviewers in the US and Mexico say it contains a cat that stands to pee. The pan is stainless steel with rounded corners that are easy to scoop. One reviewer says it holds two full boxes’ worth of litter.
Possible Downsides
Your cat has to climb in and out through the top. A big cat needs to be comfortable jumping to use it.
Best For
Large, agile cats that are comfortable entering through the top, especially in homes where high walls are useful.
LEMPISH Smart Odor Control Cat Litter Box with Cover
Why It Stands Out
It’s a covered box at 25.9 x 18.15 x 16.38 inches, and the listing describes a powered odor-control unit with an infrared sensor. Two reviewers report a good fit for large cats, one with two 20 lb cats and one with a 19 lb cat. One detailed reviewer says the wall height and shape let her cat turn around comfortably. Several reviewers describe cleaning as a quick dump and wipe.
Possible Downsides
It’s enclosed, so make sure your cat already accepts a covered setup.
Best For
Large cats that already use covered boxes.
KittyGoHere Litter Box
Why It Stands Out
The pan is 24 x 20 inches with a 3-inch front entry and a 5-inch overall height. That’s a big floor in a very low box. Reviewers mention Maine Coons and Persians fitting comfortably.
Possible Downsides
At 5 inches tall, it won’t contain hard digging or high spraying.
Best For
Maine Coons that step into the box rather than hop in, and squat low.
Frequently Asked Questions
Does a Maine Coon need a covered litter box?
No. Tall walls handle high spraying without a lid. A cover is a preference, not a need.
Can a Maine Coon use a top-entry box?
Some Maine Coons can use a roomy top-entry box comfortably. If your cat doesn’t readily enter and exit it, a front-entry design is the better fit. Our best top entry cat litter box guide covers more options.
What if my Maine Coon still pees over the side?
Look at where it’s escaping. Over the top means you need taller walls. At the base means a seam is leaking. Our high wall litter box guide compares tall-walled options.
Is a storage tote big enough for a Maine Coon?
A large storage tote can give more floor space than many commercial litter boxes. Measure the usable interior against your cat just as you would with a purpose-built box.
