All large cat litter boxes

Little essentials. Lots of love.

23 products

This page narrows our litter boxes down to the big ones: extra large and XL stainless steel boxes with and without lids, high-sided open boxes, fully enclosed boxes with front entry and top exit, a dual-entry convertible box and large covered boxes with drawers. It is for large breeds such as Maine Coons, Ragdolls and Norwegian Forest Cats, cats who dig hard, and homes where two cats share space.

Why size matters for big cats

A cat should be able to step in, turn around and dig without part of its body hanging over the edge. A large cat in a standard box often ends up with its rear end outside the tray, which means urine on the floor and a cat that starts looking for somewhere else to go. The ASPCA notes that most cats prefer large boxes they can enter easily.

A common rule is a box about one and a half times your cat's length from nose to base of tail. For a Maine Coon that can be 30 inches or more, which is beyond most standard boxes.

Stainless steel large boxes

Several of the XL boxes here are stainless steel. Steel does not scratch or absorb odor the way plastic does over time, it is easy to disinfect, and it lasts for years. High-sided steel boxes hold in litter from strong diggers and stop cats that stand to urinate from spraying over the edge.

Enclosed steel boxes add a lid with a front door, and some include a metal scoop and holder. Open steel boxes with a lower front cut are easier for older cats to step into.

Enclosed and dual-entry boxes

Large enclosed boxes with a front entry and top exit, odor-locking designs and drawers give a big cat room inside while keeping litter contained. A dual-entry convertible box can be used open or with a lid, which helps if your cat is unsure about covers, since many cats dislike them.

Inside an enclosed box, check the interior height. A large cat needs to stand without crouching, so a tall lid matters as much as the footprint.

Large boxes for multi-cat homes

An extra large box is useful where cats share, but it does not replace the ASPCA's one box per cat plus one. Two cats still need three boxes, spread around the home rather than lined up, because one dominant cat can guard a single area.

A large box is a good choice for the main station, with standard boxes elsewhere. Scoop daily; a big box holds more waste, and cats will avoid a dirty one regardless of size.

Easy entry for large and older cats

Big cats are often heavy, and heavy cats can develop stiff joints as they age. A box with a low entry point, or a high-sided box with a cut-down front, lets them step in without a jump. Top-entry boxes are a poor choice for large or older cats.

If your large cat starts going beside the box, crouching awkwardly or straining, try a lower, bigger box first, and see your vet if straining or frequent trips continue, especially in male cats.

What size litter box does a Maine Coon need?

Aim for a box about one and a half times your cat's body length, often 30 inches or longer for a Maine Coon, with a high back and a low entry.

Are stainless steel litter boxes good for large cats?

Yes. They are durable, do not hold odor, come in extra large sizes and the high sides contain litter from big cats who dig hard.

Can two cats share one large litter box?

They can use one, but the ASPCA recommends one box per cat plus one extra, so two cats should have three boxes.

Do large cats prefer covered or open litter boxes?

Many cats prefer open boxes. If you choose an enclosed box for a large cat, check that the interior is tall enough to stand up in.

What is the biggest cat litter box I can get?

The largest here are extra large stainless steel and enclosed boxes. Check each listing's interior length and height against your cat.
