Important Features


The size of the litter box you choose for your large cat will be more important than you think. If your litter boxes are too big or too small, your cat might end up avoiding them and making a mess somewhere else. 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 clean 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 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

Front entryways are pretty standard for most 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 you 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.

Enclosed or Open Top

Both enclosed and open top litter boxes have their own unique benefits and downsides to consider. You 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.

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

Designs and Colors

Finding a 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 may cost a little extra than most other normal litter boxes, but it may 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 you are more sensitive to strong smells, it might be best to find a litter box that can guarantee that it will provide 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 open 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 at bay.

Some litter boxes even have carbon filters built inside of them that will help remove some of the strongest odors so you 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 it 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 Large Cat Litter Boxes

Amount of Litter Boxes

Many people 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 litter box for each cat in your house, plus one 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 and 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 litter box to get, there are many certain factors to keep in mind. Furthermore, you should take the size of the litter box you need 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. Elderly 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 decide to get, make sure that your cat will be comfortable using it and that they will be able to account for any problems your cat may have.

Location of the Litter Box

Determining the location of your litter box will also be essential to your cat’s comfort. There may be a space within the house that your cat has 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 and to keep all of your cats comfortable in their own spaces.

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 cat you have, is about 1.5% of the length of your cat’s body minus their tail.

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

Do Cats Prefer Open Top or Enclosed Top?

Large cats will typically prefer open top litter boxes over enclosed top ones. Open top litter boxes will allow them 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 the cat discomfort along with the feeling of being closed inside. Unless your cat is already trained to use an enclosed top litter box, an open top litter box will be your best bet.

Why Cats Won’t Use the Litter Box

If your cat will not use the litter box, there may be a chance that your cat has a medical issue that you are currently unaware of, or there is also a possibility that your cat is 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, assuming that they do actually have a medical issue. If a medical issue is not responsible for your cat not using the 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 in order to be able to use their litter box. This can also be true in the case of switching the style of your cat’s litter box, changing the location of it, or changing what kind of litter you put in it. If your cat does not easily accept their litter box right away, try taking a small amount of used litter and placing it in the corner in order to attract them to the litter box more effectively. This will likely give them the encouragement that they need in order to adjust to their new litter box or any changes in their environment.

Tips to Maintaining Litter Boxes

Clean Litter Boxes Frequently

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 does 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 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 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.

You 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 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.
