Best Litter Boxes for Large Cats

Litter Box Priorities

According to Dr. Lisa Pierson “urinating and defecating outside of the litter box (…) is one of the most common reasons for a cat to be relinquished to a shelter”. Because this is so common, it’s important to understand what your cat wants in a litter box.

Cats want a box that is clean, large enough to turn around in, and in a location, they feel comfortable using.

Individual cats may also have preferences about the smell and texture of the litter they’re using, the ease of entering and exiting the box, and whether they will urinate and defecate in the same box or would rather use separate ones for each activity.

As cat owners, we want a box that is easy to scoop and keep clean. Odor elimination, visual aesthetics, durability, and shape/size are important factors when choosing a box, too.

Resolving inappropriate elimination may be as simple as changing the litter box to something that makes both of us happy!

How Large Should My Litter Box Be?

Average litter boxes at most stores are twenty (20) inches in length, and the average cat is approximately eighteen (18) inches from nose to hindquarters.

Ideally, the litter box should be one and a half times the length of your cat, and wide enough for them to turn around with ease.

In addition to offering additional space for your pet to move, larger boxes mean your cat has more room to avoid solid waste and clumps.

In a study from Nestle Purina, it was noted that odor and use by another cat were much less significant deterrents from using a box than the presence of solid waste.

Large, exotic cat breeds such as Savannahs, Bengals, and Maine Coons are experiencing a rise in popularity. At the same time, pet obesity has been on the rise over the past 25 years.

The Association for Pet Obesity Prevention states that overweight pets are at an increased risk for arthritis, affecting their mobility.

Whether your cat is overweight, an exotic breed, or just large, many traditional litter boxes may not provide the space your pet needs.

6 Things to Keep in Mind When Getting a Litterbox for a Large Cat

Big cats need big space. They need big beds and big pet carriers and big food bowls. And when it comes to litterboxes, you can bet they require big ones of those as well. Having an appropriately large box to do their business in is good for them and is also good for your home.

It keeps things cleaner in and around the space where the litterbox is kept. It also keeps your big cat more comfortable when they are going to the bathroom.

A comfortable cat is a happy cat, as all feline owners know. Here are some tips to keep in mind when getting a litterbox for your large cat.

To Cover or Not to Cover

A fully enclosed litterbox may seem like a great idea, as it hides the look and some of the smell of the feline ‘toilet’, but for a large cat, a covered litterbox can be more of a hindrance than a help. Many covered litterboxes have only a small doorway, as well as a narrow amount of space inside.

Large cats can find it difficult to move in and out of the box, as well as turn around once they are within it. They may start refusing to use a covered box as it is so uncomfortable for them.

It can also be much messier with a large cat, as they’ll end up going on the insides of the cover instead of in the litter. When you open the box to clean it you may find a gross mess that you weren’t expecting.

If you really prefer an enclosed box and you aren’t able to find something in a store that works for you, you can make your own covered litterbox by purchasing a large plastic bin with a lid and cutting a big hole in the side. Be sure this hole is tall enough that litter won’t spill out but low enough that the cat can get through it.

A large DIY-covered litterbox may be more acceptable to your cat than some of the ready-made versions. Make sure you can still get in to clean it easily on a regular basis. You’ll also want to smooth out or tape over the edges when you cut the entrance hole.

You don’t want your cat to scratch or cut itself going in and out. Not only could it get sick from an infected scratch, but it could also decide it is uncomfortable using the entryway and refuse to go inside.

The Bigger the Better

Litterboxes come in several sizes, but most are geared toward small or average size cats. This means it can be difficult to find one that works well for a large cat who needs more space. When purchasing a litterbox you should look for one that is not only deep but long and wide.

This will give your cat plenty of room to maneuver when they are using it. Some cats like to use one corner or side of the area to do their business. If the box is too narrow or short, they may end up going to the bathroom outside the box by accident.

It is a good idea to measure your cat before picking out a litterbox for them. Make sure the box is longer and wider (possibly two times wider) than they are. If you currently have them using a small litterbox but are wanting to upsize, you should watch how they use the current area before you go shopping.

You will be able to pick out a better new box for them once you know not only how much space they need, but how they will use that space. Each cat is different in how they go to the bathroom and it’s important to remember that when buying their box.

Like with the covered box idea, if you can’t find a litterbox that seems big enough, you can always make one yourself. Buy a big, square, plastic bin (you don’t need to purchase the lid as you won’t use it) and set it up where your cat is used to using a litterbox.

As long as it has a litter in it and is easy for them to get in and out of, they won’t care that it wasn’t originally intended to hold their waste.

Bless This Mess

Litterboxes can be messy. They are filled with sand and used as toilets. Even if you have the neatest cat in the world, a mess will probably accumulate around the litterbox.

Big cats especially can throw litter (and sometimes feces) around the room when trying to bury things after going to the bathroom. They will also often track litter from the box onto the floor around it – and maybe even to the rest of the house!

To cut down on the mess, put a litter-catching mat under the litterbox. If you have space around your litterbox, get a mat that is quite a bit bigger than the base of the box.

This will give the cat extra space to knock litter off their feet (and from between their toes) before they track it across your flooring or onto the furniture.

Sharing is Not Always Caring

Cats are not always great at sharing. They tend to like their own food dishes, their own napping spots, and their own share of cuddle time with their people. This means if you have multiple cats – and you have the room – you should have multiple litterboxes. This way each cat has its own ‘territory’.

This is especially helpful when one or both of your cats are on the larger side. You can buy a box that works for the size of each cat, instead of trying to push a small cat to use a huge box or a big cat to use a tiny one. You can also use different litter for different cats if necessary.

Maybe one kind of litter works better with big messes as your large cat makes. You can fill their box with that litter and then use something else for another cat.

Shop Around

Like with many things, you don’t necessarily want to buy the first litterbox you see when you go shopping. Oftentimes physical pet stores will have small or average size boxes on hand because those are what they sell the most.

It may take two or three stores before you find any larger-size litterboxes to look at. It’s also a good idea to look at other kinds of stores.

Big Box, feed stores, and outlet stores may all carry litterboxes (as well as other pet care items). These kinds of stores may not carry as many items as a pet store, but they are worth checking out because sometimes they have the items other stores couldn’t see. Such as large litterboxes.

There is also online shopping that you should consider. Because these retailers do not have a physical store with limited space, they can carry a lot more brands, sizes, and styles of litterboxes. You may have more luck finding a box the exact size you want if you look online.

Many virtual stores also offer free shipping if you spend a certain amount of money. You can purchase other needed items for your large cat at the same time you are getting their litterbox.

Keep Your Options Open

Sometimes it takes trial and error before you find the right litterbox for your cat. You may get one that is too small or too shallow the first time. You may get one that has a funny shape or is even the wrong color.

It can be hard to tell what a cat will prefer to use before you give it a try with them. Some large cats are fine with a covered box or one that seems a little small. Others can’t function properly without a lot of open space and a perfectly square area.

It’s important to realize that it may take more than one try to find the litterbox that will work long term. Do yourself a favor and don’t spend a lot of money on any box if you don’t have to.

When you are shopping around, keep an eye on prices as well as other elements. Only buy an expensive litterbox if you are absolutely sure it will work perfectly for your cat and in your home.

Owning a large cat doesn’t have to be a large problem. If you keep in mind that their needs will be different than those of a small or average size cat, you’ll be able to set them up with properly sized food bowls, beds, toys, cat trees, and litterboxes.

It may take a little time and effort to come up with exactly what is necessary for them to lead healthy and happy lives, but as long as you are willing to put the time in to research their needs, experiment with different items, build or repurpose as necessary, and give your cat time to acclimate, things should work out relatively well.
