Litter Box for Multiple/Big Cats Buying Guide

Best Litter Boxes For Big CatsOne of the most difficult aspects of being a dog mama is having to walk your dog every morning and every evening. It does not matter if you are sick or if it is terribly cold outside because the dog has to go out to do its business and you have to take it out. In comparison, the toilet business with cats is relatively easy. All you have to do is to choose the most suitable cat litter box and the best cat litter. After that, it is all about daily cleanups.

When you have multiple cats or a large cat, the cleaning up part takes a little bit longer but the most important point is to choose a litter box that can accommodate a big cat or more than one cat. Here are a few tips on how to choose the best cat litter box for your large cat and/or multiple cats;

1. What Size Litter Box Should I Have?

Cats actually do not mind getting into litter boxes to do their business. However, they do mind the size of the litter box. If a cat cannot fit and maneuver in a litter box comfortably, it may reject to use it. Remember that cats do not only squat in their litter boxes to pee but they also stretch and dig. Therefore, to give your cat enough space the litter box should be about 1.5 times the length of your cat, from the tip of its nose to the base of its tail. Your cat/cats should have enough room to urinate or defecate, cover their waste and have some more clean litter for a few more visits.

When the litter box is too small for your cat, it can cause a lot of discomfort which will lead to stress. If your cat gets stressed when inside the litter box, it will start looking for other locations as a toilet and then probably it will be you who will get stressed.

In addition to the size of the litter box itself, the size of the opening of the litter box is also important. It should be large enough for your cat to comfortably fit through instead of squeezing in. Moreover, the height of the base matters, especially in the case of kittens and old cats. Old cats with arthritis and young cats that are not fully grown may have difficulty to climb into the litter box if the base is too high for them.

2. How Many Litter Boxes Should I Have? Can Multiple Cats Share a Litter Box?

Cats are very territorial animals and they are very possessive. They value their privacy and generally do not like sharing. Their litter boxes are no exception. That is why there may be some litter box issues in a multi-cat home.  Especially if the alpha cat at home is highly dominant, it may not let the other cats use the same litter box and this may cause stress to the less dominant ones. And the stressed-out cats who are prevented from visiting the litter box by the alpha will start looking for other places to do their business. At that point, another litter box will save your carpets.

But how many litter boxes should you have then? By the rule of the thumb, a house should have the same number of litter boxes as the number of cats in the household, plus one. It means if you have two cats, you should have three litter boxes. Your cats might get along very well and may not mind sharing a litter box. Still, I highly suggest that you still keep at least two litter boxes for two cats, just in case. Choosing both of them to fit for multiple cats would be the best decision since they may end up using the same litter box after all.

It may seem like having to do the litter box cleanup twice but even if you have only one litter box, with two cats it will still be messier and you will have to change litter or wash the litter box more often. Plus, if you do not clean up the single litter box used by multiple cats often enough, they may start looking for other spots to pee and poo, again.

3. Odor Control

Best Multi-Cat Litter BoxesA large cat means a lot of mess in the litter box and multiple cats are even messier. Messier litter boxes are also more smelly. Therefore, in addition to the cat litter for odor control that you use, a litter box that has an inbuilt system to help odor elimination might be a good idea. There are a lot of litter boxes on the market which are equipped with filters for that purpose. Charcoal filters are the most common ones because charcoal is known to be very effective for neutralizing odors. Plus, they are not expensive and therefore, are not very costly to replace.

4. Hooded vs. Unhooded Cat Litter Boxes

When a larger cat digs, it can spread a lot of litter around. It is the same for multiple cats. In this case, a covered cat litter box is, of course, a better idea because it will prevent most of the litter from scattering around while your cats kick. However, you should consider some other features while deciding which one to use. Here are some pros and cons of covered and uncovered litter boxes for you to take into account;


  • There is less trailing since the cover prevents litter from scattering around. Especially if used along with dust-free cat litter.
  • The cover gives your cat the privacy it needs because cats like going to the toilet where they cannot be seen by the others.
  • If you also have a dog at home as I do, or a kid, a covered litter box is a great tool for keeping them away from the litter. Both kids and dogs love playing in the sand and they could mistake cat litter for sand very easily.
  • A covered litter box is better at keeping bad odors from diffusing into the air since they trap them inside.


  • It takes longer for the litter to dry in a covered litter box because there is less air circulation.
  • Covered litter boxes are more difficult to clean because you either need to reach in or remove the cover each time you clean it up.

5. Cleanup

As I have mentioned above, multiple cats mean messier litter boxes. You will have to clean the litter box at least twice a day which might be too time-consuming for those who work long hours. In this case, preferring a self-cleaning automatic cat litter box might be a smart solution. You will need to save more budget to get one but remember that you will be saving a lot of your precious time, as well.

Using litter mats will also help as it will collect all the litter kicked out by multiple cats.

How to Clean a Litter Box?


To sum up, the best litter box for large cats or the best multi-cat litter box should be large enough for your cats to easily fit in and maneuver inside, should be deeper and able to hold more litter than a regular size cat litter box, should have a filter for odor control and should preferably be hooded. If you stick to these features as your checklist, I believe that you will not have much difficulty in finding the best one for you and your furry friends.
