Cats like a bit of privacy. Even amongst siblings from the same cat litter, cats need a great deal of alone time to do their own thing, one box per cat. This being the case, answering nature’s call can be unsettling if you have to share a cat litter box.

Also, as all cat owners know: cats are very possessive. They are quite obsessive creatures of habit. As such, they will often trademark their favorite travel paths (portable litter box)

throughout the house. Any interruption could provoke hostility.

Cats need a nice clean space to do their business and it’s better for their health. If more than one cat is using the same litter box, a lot of poo will quickly accumulate. If they can’t find somewhere comfortable in the cat litter box to go to the loo, they will find somewhere outside it (i.e. your carpets, furniture or nearest pot plant.)

The Cat to Litter Box Ratio: The Golden Rule

The best way then is to have many litter boxes for your multiple feline housemates. The golden rule says that you should have at least one more than the amount of cats or pets you have. A great rule of thumb is to have at least 1 and a half litter boxes for every cat i.e. 1 cat – two litter boxes, two cats – three litter boxes, three cats – 5 litter boxes, and so forth.

Such a consideration will allow each cat to claim their own toilet, while having one extra box just in case.

Pros and Cons of Multiple Cats Sharing a Litterbox

No matter how much you love your cats, litter box maintenance will never be enjoyable. Though you might prefer to give your cats’ litter box as little thought as possible, taking the time to make plans before you bring home your new kitten will save you a lot of trouble down the line.



Likely the main reason someone decides to only have one litter box for multiple cats is that their home lacks space for a second one. Considering the fact that most common people do not need to have their cat’s litter box out on display, and most common homes do not have many private, hidden-away spots, this is actually quite a common problem. So technically a pro for why you would choose to have just one litter box for multiple cats is that a singular litter box will most likely take up less space than many litter boxes.


Next, though having multiple litter boxes will cost you more upfront when it comes time to buy litter, it won’t actually end up costing you anymore in litter in the long run. That being said, although litter will cost the same, there is a chance the litter box/boxes themselves may be more expensive. Since cats will likely have trouble sharing a small litter box which won’t give your cat the privacy it need and next can get dirty quickly, the best solution for multiple cats in multiple litter boxes or a larger litter box. Both of these options will end up costing you more upfront.



Cats bathe themselves and kick litter to cover up their waste, cats are clean animals, so it is really no surprise that cats prefer to keep clean box. Unless you are home all day, there is a very good chance that with two or multiple cats share one litter box, it will get dirty very quickly. What this will probably mean is, your cat will feel less inclined to use their litter box, and therefore have to look for other spots to go to the “toilet.” Although having to clean and keep two litter boxes (or more) might be a pain, cleaning smelly cat urine off a carpet is definitely so much worse.


Though many people probably associate the word “territorial” with a dog, cats can often be just as territorial as a dog, if not more. Unlike a dog who may have a whole backyard to themselves, an indoor cat really only has one private spot, their litter box. However, when two or multiple cats are forced to share a litter box that sense of privacy will be taken away, which might make your cat defensive and prone to territorial issues. This will most likely be the case if you get two new cats at once, and will most certainly be the common case if you already have a cat with an established private litter box and you introduce a new cat into the picture.

Overall, you should try and avoid your cats getting territorial issues at all costs, (whether that means getting use different litter boxes or taking away your first cat’s original box so they aren’t defensive) since one cat or more territorial felines can lead to some pretty bad catfights. These catfights can be especially bad if you have an older cat and a young kitten better not try. No matter what your situation is, one of your cats will likely be more dominant than the other, which will probably cause some serious rifts between your cats and anxiety for the more submissive one, which will affect them for years to come.

In this case, the negatives seem to outweigh the positives. Although having different litter boxes may put inconvenience for those with small spaces or tight budgets, it really is worth it to look for a way to make it work to save yourself many headaches in the future.

Having multiple litter boxes per cat really doesn’t need any extra cleaning since if you only had one litter box for multiple cats you would have to keep clean it far more often and more thoroughly to make sure your cats will be willing to use it. Overall, to answer the question, can different cats share a cat litter box, well technically, but it would be best to avoid that at all costs.

Getting My Cats to Share? Can Two Cats Get Along?

It should be obvious by now that your number of litter boxes should have at least plus one extra litter box over the amount of cats in your house. Some of the time, a cat can still have reservations about sharing his house with an impostor. What then?
