Guide To Choosing The Best Litter Box For Large Cats

A good litter box is one that is easy to clean and use, does not require frequent maintenance, lets your cat feel safe and comfortable, and reduces odors and tracking to a minimum. Apart from these basic requirements, a litter box for large cats has to meet a whole range of additional criteria in order to accommodate the needs of larger cat breeds.

Here are the extra features you should look for when searching for the best litter box for large cats.


The general rule is that your cat’s litter box should be at least 1.5 times as long as your feline friend. However, when shopping for a litter box for a large cat, you are unlikely to find a litter box that is huge enough to meet this requirement. That is because it is simply not necessary.

A cat that measures 10 inches in length can use 5 inches of free space to move around and dig, but a cat measuring nearly 30 inches in length does not really need 15 inches of extra space to feel comfortable. Plus, it would be really difficult to fit such an enormous litter box in a small apartment or even in a larger house without it becoming the centerpiece of a room.

Thus, you should make sure the litter box is large enough to provide a couple of inches of extra space on all sides, so your cat can move around comfortably. Still, there is no need to go overboard and get a litter box that is as big as your bed, as it would be hard to find a location for it and thorough cleaning would take much longer.

Litter Capacity

Larger cats need deeper litter beds to accommodate their digging needs. Therefore, while there is no need for a litter box to be 1.5 times the length of your cat, its litter area should definitely be deep enough to prevent urine from collecting on the bottom and let your cat dig easily. The litter area should be tall enough to receive at least about 4 inches of litter while leaving about an inch above the fill line to prevent frequent litter spills.


Currently, there are too many litter boxes that can allegedly accommodate large cats, but their entryways are too small to let a Maine Coon get inside easily. If a litter box features an entryway that is not at least a couple of inches wider and taller than your cat, it does not constitute a good fit for your feline friend and it may force your pal to do his or her business elsewhere.


The best litter box for large cats is the one that is designed to keep the litter inside the box, suit the needs of side pee-ers, and let a large cat stand up comfortably without feeling cooped up. Thus, you should opt for a non-claustrophobic, open-top litter box with high sides to prevent spillovers or a covered litter box whose height allows your cat to stand tall without crouching.

Waste Capacity & Removal

The criterion of waste capacity and disposal is particularly important for self-cleaning litter boxes for large cats. Namely, due to the size of waste clumps, it is important to get a litter box with a large waste receptacle, so you do not have to dispose of waste every day. It is also crucial that the cleaning system is suitable for large waste clumps, so there is no clogging. Sifting systems with a wide waste chute are the best choice.

If you are getting a traditional, non-automated litter box, you can opt for one that comes with accessories, such as a scoop and rake compartment, to speed up and facilitate the waste removal process. You may also want to get a special trash can just for disposing of waste clumps and soiled litter and empty it as rarely as once a week instead of taking out the trash after every scooping session.

Odor Control

Bigger waste clumps pack extra odors and without adequate odor control, your home is bound to get smelly unless you scoop right after your cat has used the toilet. The best litter boxes for large cats are designed to prevent unpleasant smells from spreading and kill odor-causing microorganisms. When choosing the best litter box for your cat, you should look for odor-control features like closed waste compartments, carbon filters, and anti-microbial protection.

Tracking Control

The larger the cat, the larger the amount of litter that can get kicked out and end up on the floor. The larger the paws, the more litter can get stuck on them and get scattered across the room. Although good tracking control is always desirable, it is particularly important in litter boxes for large cats.

From high sides to paw-cleaning ramps, there are a variety of ways tracking and spillage can be minimized. You should make sure that the litter box you choose possesses at least 1 tracking-prevention feature that can reduce the amount of mess you need to deal with on a daily basis.

Stability & Durability

If a litter box is too lightweight, a large cat can easily flip it over while exiting the box. That is why you should always look for a litter box that is stable and heavy enough to stay in place even if your cat steps on the edge while getting out.

Furthermore, it is important to pick a litter box that is made of durable materials and features a sturdy construction. That way, you can be sure that even if your cat gets playful, the litter box will not suffer significant damage that would require replacing parts or the whole litter box.


Just because your cat needs a bigger litter box, it does not mean that the litter box should come with a much bigger price tag. Some of the best litter boxes for large cats are surprisingly affordable, they do not require many pricey accessories, and they can even help you save money on litter.

A litter box for large cats is only worth splurging on if it can make your life significantly easier. In other words, it makes sense to pay more for extra convenience, but you do not have to pay more for your cat to get extra space.
