Can two cats share one litter box?

According to experts in feline behavior, it is not advised to provide two cats with only one litterbox. In fact, these experts recommend to have an equal number of litter boxes to that of cats, plus one. In other words, if you have two cats, you should provide them with three litter boxes.

Why? Well, there's two main reasons: behavior and health. On the first hand, cats are territorial animals that need to have their own space for certain things. One of the most personal things felines do is urinate and defecate. In the wild it leaves them vulnerable to predators so they need to be on an alert. In the comfort of their own homes, most domestic cats prefer to have their own litter box with their own smell for their necessities.

Another important reason is health. Having two cats urinate and defecate in the same litter box will lead to a litter box full of bacterias. If you work away from home and don't have time to clean it every time they use the litter box, this is not ideal. The accumulation of their feces can lead to health issues. This is why it's best that they have their own litter box and an extra on just in case.

This way, they both feel safe and comfortable in their own litter box. The litter boxes will also be more clean and therefore help prevent any infections. So, even if your two cats don't mind sharing one litter box, it's best to provide them with 2-3 litter boxes for health reasons.
