Can Cats Share a Litter Box?

Litter boxes can be a pain to find, and even more of a pain to keep clean. With that in mind, it’s natural to wonder: can cats share a litter box? The short answer is simple: no.

While cats can share litter boxes if they absolutely have to, most will naturally choose to find their own spots to relieve themselves. While it may seem like a hassle to have to take care of multiple litter boxes, in the long run, it will be far simpler and more comfortable to make sure that you have a litter box for each of your four-legged friends!

Why Is It Bad?

Can cats share a litter box? Technically, yes, but that doesn’t mean that it’s good for them. Just like humans, cats tend to value privacy and security when they relieve themselves, and forcing multiple cats to share the same space can lead to some issues.

  • If your cat feels like their space isn’t just for them, it can lead them to feel insecure or uneasy. Besides, you may have noticed your cats retreating to their litter boxes, not only when they have to go to the bathroom, but when they need to be alone. If multiple cats are sharing the same litter box, this can create tension among cats who are looking for some breathing room.
  • The biggest problem with multiple cats in the same box is that cats are territorial. The same instinct that inspires your cats to rub their heads against their favorite people and places is the same instinct that will make them uncomfortable sharing the same space to do their business. When multiple cats are using the same litter box, they’re all essentially claiming the same area as theirs. While some cats have a laid-back personality and don’t mind sharing spaces with their friends, more territorial cats may take this as a direct challenge of their authority. As a result, you may find yourself having to intervene in feline feuds that will take up a lot of your time and energy.
  • If your cats feel uncomfortable using the litter box you’ve provided for them, they can and will take care of their needs elsewhere. This can cause a lot of problems for you as a pet owner, as you may find yourself having to clean up inconvenient messes around your house or your apartment, instead of just having to clean out the litter box.
  • Again, while some cats may seem not to have an issue sharing a litter box, it’s better to use multiple litter boxes. Doing so will reduce stress between your cats, and as a result, will significantly reduce the amount of stress that you have to deal with as their owner.

Problems You Might See

If you’re currently using the same litter box for multiple cats, or even if you’re just considering expanding your family, you may want to keep an eye out for certain warning signs that using the same litter box isn’t working.

Behavior problems

  • Behavior problems can cover a wide variety of issues, but the key point you may notice among your cats is increased aggression. Cats aren’t pack animals, so being forced to share the same space is almost naturally going to result in heightened tension. If you notice a higher number of disagreements between your cats or see that your cats are acting more territorial than usual, it may be time to expand your fleet of litter boxes.

Health problems

  • Health problems don’t always arise as a direct result of sharing the same litter box, but if multiple cats are using the same box, it can be more challenging to track health issues among your cats. If each cat is using their own litter box, then it should be easy to quickly identify any problems that individual cat is having, based on the regularity and appearance of their stools. If multiple cats are using the same box, on the other hand, it can be harder to figure out which cat is having a health problem.
  • With multiple cats using the same box, the risk of cross-contamination increases significantly. Cats don’t like walking through each others’ waste any more than humans do, and the particular germs and microbes that each cat naturally hosts can travel more easily between animals in the same box.


  • Accidents, as mentioned above, are a pretty prevalent symptom when your cats are feeling cramped in the same litter box. Most of the time, rather than continue to share the same space with a lot of other animals, cats will find other places to take care of their business. If you find yourself cleaning up more and more messes around your home, it may be a direct sign from your cats that they feel too uncomfortable to share the same litter box.

What Should I Do Instead?

  • As a general rule, you should have one litter box for every cat, and then one extra. This may seem like overkill, but it allows your cats to establish their preferences and feel confident in their own space. The extra litter box provides a fallback if one cat feels uncomfortable using “their” litter box for whatever reason. The extra space will give them a space to eliminate waste while still saving you from having to clean up their messes until you fix whatever was wrong with their box.
  • With each cat feeling confident in using their own litter box, you’ll quickly be able to figure out which cats prefer which types of litter, as well as any other preferences for litter box position, privacy, or proximity to other large objects like furniture.
  • If your cats are sharing the same litter box right now, they may not jump at the opportunity to use multiple litter boxes right off the bat. Give them time, and they should acclimate to the new space, but you can also coax them along.
  • Try placing the old litter box closer to the food if you want your cats to stop using it, as most cats are naturally averse to taking care of business so close to a food source. You can also try “assigning” litter boxes by physically placing each cat in a separate box and encouraging them to scratch at the litter until they’ve established that that space belongs to them and to no one else!
  • If you’re worried about the time that it takes to clean out multiple litter boxes, there are a lot of self-cleaning litter boxes or easy-to-clean boxes that can greatly reduce the amount of time you have to spend.
  • If space is a major concern, you may want to look at compact litter boxes that will help you save room in a crowded apartment or busy floor space. Overall, no matter what your primary concern with multiple litter boxes may be, there are enough pet-owners just like you that there’s almost guaranteed to be a litter box to suit your needs.

Things to Keep in Mind

  • Place your cat’s litter box as far apart from each other as possible. A typical behavior that crops ups when multiple cats are using the same box is referred to as “guarding” or “stalking”. The more dominant cat may block weaker cats from using the litter box entirely, which can lead to a spike in accidents as well as heightened tension between your four-legged friends. As a result, place the litter boxes as far from each other as your house or apartment will allow. This will make it physically impossible for the dominant cat to block every litter box at the same time, and will reduce the amount of stress both on your cats as well as your floors!
  • Take a little bit of extra time to make sure that all of the litter boxes are cleaned as regularly as the original litter box once was. If one litter box fills up faster than the others, the cat that uses that box may go in search of greener pastures.
  • If you notice your cats arguing over the same litter box, this is where that extra litter box may come in handy. It may take time, but make sure that your cats know which space belongs to them and that it will be clean and private enough for them to feel secure.
  • Each cat family is unique. Most cats prefer their own space, but if you believe that your cats are truly comfortable using the same litter box, you may want just to try one or two extra boxes.

Fortunately, cats usually do a pretty good job of letting their humans know what they want, so study your cats’ behaviors. If they seem perfectly happy using the same box, then give them an extra backup box just in case and let it rest.

If you notice any unusual aggression in your cats, however, giving them the space they need can help them feel safe and confident.


Can cats share a litter box? At first glance, it may not seem like a problem. They may get along for a little while, or they may not seem to be having any issues. However, for their health and mental well-being, it’s not a good plan for them to share a litter box long-term.

Sharing a litter box can lead to a wide variety of behavioral issues, and can ruin the peace between your furry friends. Investing in multiple litter boxes, or at least a litter box that’s designed for multiple cats, can go a long way towards keeping a happy home.
