Important Features to Choose the Right Large Litter Box


The size of the litter box you choose for your large cat will be more important than you think. If your cat litter boxes are too big or the box is too small, your big cat might end up avoiding them and making a mess somewhere else rather than using the box. You will want to make sure that you get a litter box that is appropriately sized for your cat and take their own size into account while you are purchasing a litter box or pan for them.

Choosing the right size will help to prevent them from becoming uncomfortable in their own bathroom space.


A self-cleaning litter box is best for you and your cat if you are unable to maintain their litter box yourself for any reason. Getting a self-cleaning litter box will make your job a whole lot easier and can save you the stress of being near the scent of litter for too long.

Different self-cleaning cat litter boxes have different self-cleaning methods, so you will want to pay attention to the methods they use to find the one that will work best for you and your cat.

Front or Top Entryway

The front of the litter box entryways are pretty standard for the best cat litter boxes, but there are also some that exist with a top entryway. These types of litter boxes usually help to prevent litter from escaping the box when your cat goes to use it, saving cat owners from cleaning a lot of unnecessary messes.

The only discernible problem is that your cat may have to work towards learning to use a litter box with a top entryway (iris open top cat litter box) if they are already accustomed to using ones with a front entryway as they enter and exit the box.

Enclosed or Open Top

Both enclosed and open cat litter boxes have their own unique benefits and downsides to consider. Cat owners will have to pay close attention to your cat’s own litter box preferences in order to determine which one they will be more comfortable using whether your cat likes the enclosed or open top.

Enclosed cat litter hooded boxes might give your cat more privacy while they are using them and keep odors out of the air more often, but they might also make them uncomfortable by keeping them in a tighter space which can give them anxiety. Open litter boxes are easier to maintain and will give your cat more space to turn around, but they will also allow odors to permeate throughout the air.

Designs and Colors

Finding a kitty litter box that has unique designs and colors can add to the overall aesthetic appeal of the rest of your house instead of ruining it, and can also prove to help your cat be more comfortable in its environment. They might cost a little extra than most other normal litter boxes, but it might be worth it in the long run if you do not want the litter box to ruin the appearance of the rest of the room.

Odor Control

If cat owners are more sensitive to strong smells, it might be best to find a litter box with an excellent level of odor control, along with a litter product that will promise the same.

Enclosed litter boxes will give you better odor control than top litter boxes. It may work best in your home if your cat is already more adjusted to using enclosed litter boxes. Double the enclosed litter box with litter that provides a decent level of odor control, and you will have a litter box that will keep the odor inside the box.

Some litter boxes even have carbon filters built inside of them that will help remove some of the strongest odors so cat owners will not have to be exposed to them. There are also some litter boxes that are built with doors that have small holes for air ventilation so that they can prevent odor and bacterial growth from occurring within the litter box.

Odor control is an important part of litter boxes, so be sure to check on that.

FAQ Regarding the Best Litter Box for Large Cats

Number of Litter Boxes

Many cat owners wonder how many litter boxes they should have in their house if they own multiple cats. The standard rule of thumb is that you should buy one best litter box for large cats and one litter box per cat in your house, plus an extra one to prevent crowding and the chance of your cats fighting each other.

Make sure the litter boxes are also large enough to hold multiple cats. Space them out within different areas of your home to make sure that you have enough room for all of your cats.

What Kind of Litter Box to Get?

In order to determine what kind of best cat litter box to get for your cats, there are many certain factors to keep in mind. Furthermore, you should take the size of the litter box into consideration during your search.

You will definitely need larger boxes for larger cats, but smaller and younger cats will become quickly accustomed to medium sized litter boxes. Older cats with mobility issues or disabled cats will need litter boxes that are more easily accessible, so they will have less difficulty getting in and out of their litter box.

Regardless of what type of large litter box you get for your cats, make sure that your cats will be comfortable using it. Try to account for any problems your cats may have.

Location of the Litter Box

Determining the location of your litter box will also be essential to the comfort of your cats. There may be a space within the house that your cats have already taken an interest in; that is likely where they will want to have their litter box placed.

If you have multiple large cats and multiple litter boxes, space them out around your house to prevent the odors from mingling together. This will keep all of your cats comfortable in their own spaces.

How Big Should a Litter Box be for a Large Cat?

In general, ensure that your litter box is a minimum of 1.5 times your cat’s length! If you’re ever not sure which to choose, always choose one that’s bigger. After all, it’s better for your large cat to have more space.

Why Big Cats Need Large Litter Boxes

Large cats can normally only use litter boxes that will fit their size, and that will allow them to move around comfortably. The rule of thumb for litter box sizes, regardless of how old they are or what kind of cats you have, is about 1.5% of the length of your cat body minus their tail.

If their litter box does not accommodate the size of your cats, you may have to size, or your cats will end up making a mess outside of the litter box.

Jumbo Cat Litter Boxes with High Walls

Something else to consider when you’re looking for a litter box are the high walls. Cats often have a habit of urinating above the wall of the box and end up staining your house wall. Having a high wall keeps your cats from making a mess in your house by also keeping the litter inside the box instead of spreading it around on your floors.

If you’re really worried about the mess of your cats, consider getting a litter box with a hood.

Do Cats Prefer Closed or Open Litter Boxes?

Large cat breeds will typically prefer open-top litter boxes over enclosed top ones. Litter boxes that are open will allow cats to move around more freely and gives them the option to keep an eye on their surroundings while they are using it.

Enclosed litter boxes are beneficial to the owner because they allow the odor from the litter box to remain masked inside. But that might also cause cats discomfort along with the feeling of being closed inside. Unless your cats are already trained to use an enclosed top litter box, an open top litter box will be your best bet.

Yes, cats prefer larger litter boxes.. When it comes to larger cat breeds, a roomy litter box really makes a difference. As a minimum, make sure the litter box size is at least 1.5 times your cat’s length. This is measured from your cat’s nose to its tail tip when extended. As for the width of the box, make sure it’s the same as your cat’s length (with an unextended tail).

Actually, we have some really affordable options on our list, which is worth getting to save you the trouble of having to DIY a box yourself.

How Do I Know if my Cat’s Litter Box is Too Small?

At a minimum, your cat must be able to turn around inside the litter box easily. If it can’t, then the box is certainly too small and not suitable for cats. You’ll also know if your cat refuses to go in, use it, or your cat is having difficulty going in. Sometimes, your cat may pee over the edge as well.

Why Cats Don’t Use the Litter Box

If your cats will not use the litter box, there may be a chance that your cats have a medical issue that you are unaware of. Or there is also a possibility that your cats are uncomfortable with their litter box or that the litter box is too full.

Consulting your local veterinarian is the best way to find out what is bothering your cat and how to fix it for your kitty, assuming that they do actually have a medical issue. If a medical issue is not responsible for your cat not using the a great litter box, try cleaning the litter box more frequently, changing the location, use different types of litter, or change the size of the litter box until your cat is more satisfied with it.

How to Help Your Cat Adjust

Sometimes, your cat will need some time and encouragement to be able to use their litter box. This can also be true in the case of switching the style of your pet’s litter box, changing its location of it, or changing what kind of litter you put in it.

If your cat or kitty does not easily accept their big litter box right away, try taking a small amount of used litter and placing it in the corner to attract them to the litter box more effectively. This will likely give your kitty the encouragement that they need to adjust to their new litter box or any changes in their environment.

Tips for Maintaining Litter Boxes

Clean Litter Boxes Frequently

Large litter boxes need to be cleaned as frequently as possible in order to keep it fresh and to keep your cat comfortable using it. Change the litter out at least twice a week and clean the inside of it, so the older litter and residue do not stick onto the box before changing the litter.

You may want to wear gloves and possibly a mask to keep from breathing in the urine smell. Antimicrobial soap and warm water will do the job when you are ready to clean out the interior.

Prevent Wasting Litter

When you are refilling your cat’s large litter box, make sure that you only pour enough to fill one third of the inside so your cat will have enough space to move around and so that your cat does not accidentally end up making a mess around the litter box.

It is also important to be certain that the litter you use for your cat is its preferred litter so that they are not tempted to avoid their large litter box.

How to Make a Reusable Litter Sifter

Litter sifters are also pretty easy to make on your own and can be used for many types and sizes of litter boxes. If you are using a storage tote as a litter box, find another tote that is slightly smaller than the one you are using for the litter box and drill some holes into the sides and bottoms of it before placing the new litter inside of it.

Cat owners can then use the smaller storage tote to sift through the urine and feces to dispose of it while leaving the unused litter in the main compartment of the litter box. This is both cost efficient and provides a more convenient way of cleaning your cat’s litter box and it is definitely worth a try if you are willing to put your DIY skills to the test.

Another way to make a reusable litter sifter is by using nesting buckets to dump the contents of your cat’s litter box into. The materials you will need include two nesting buckets, hardware cloth, and a suitable adhesive. You will methodically cut the bottom off of one of the buckets you are using, cut the hardware cloth by using the bucket top as a guide, snip each wire with a dremel or side cutters to match the top of the bucket, and then you will assemble the bucket top and the mesh.

Use the adhesive to stick the mesh to the bucket top place that bucket top into the untouched bucket. With your litter sifter now complete, you will be able to dump the entire litter box for large cats into it in order to separate the filthy litter from the clean litter. It may be time consuming, but it is simple enough to make and it will help you have an easier time cleaning the litter box.


Large domesticated cat breeds can reach up to 25 pounds in weight. To house these big, cuddly, gentle souls, you must have enough room and the right equipment. Choose from these extra large cat litter box options and litter pans on the market without having to worry about hygiene and mess anymore.

Do not forget to give your cat enough time to get adjusted to their new best large litter box. It may be a long process to follow, but it will be worth it to choose the right one. Give them the encouragement they need so they can be more comfortable.
