Can Two Cats Share A Litter Box? Things You Need To Know!

Cleaning and maintaining a cat litter box is undoubtedly the most unpleasant aspect of cat ownership, and managing many litterboxes makes it much worse. If you have two cats, it makes obvious that you would want to use a single litter box for each of them. However, is this feasible and hygienic?

While it is feasible to utilize a single litter box for a single cat, it is far preferable to adhere to the litter box golden rule: one litter box per cat plus one extra. This makes their litter box cleaner and decreases the likelihood of fights. Although it may seem contradictory, this really requires less labor than a communal litter box.

"Can Two Cats Share a Litter Box? Things You Need to Know!" by BestForPets (bestforpets.org) shows an explanation of why.

Why cats should have their own litter box

You should have one litter box per cat plus one additional box. This logic is based on two factors: hygiene and behavior.


Sanitation is the most crucial reason why cats should have their own litter box. Two cats using a single litter box will quickly cause the box to become unsanitary. If you’re away from home or don’t have the opportunity to clean the litter box, not only are your cats unlikely to use it again, but it can also house potentially deadly germs that can cause health problems.


Cats are extremely territorial and like to relieve themselves in their own private place. Forcing cats to use the same litter box can result in tension, anxiety, and territorial disputes that can escalate to fighting. The dominant cat of a pair might prevent the other from using the litter box, forcing them to urinate or defecate in other areas of your home, or it could lead to your cat postponing urination, which could result in renal problems.

What about litter boxes that clean themselves?

It is reasonable to presume that a self-cleaning litter box may be acceptable for two cats; since it remains clean, there is a reduced risk of health issues.

The issue is that these litter boxes will not be able to completely eliminate waste, therefore the risk of bacterial growth remains. The second concern is that your cat will still be able to smell the cat that used the litter box most recently, which might result in territorial behavior.


Placement of your cat's litter boxes

Territorial disputes may still occur if you place your cat’s litter boxes in the same area. You should place the litter boxes on opposite sides of your home, with a third litter box in the middle. This might be tough in a tiny home, but it is essential if you want your cats to use the litter box.

Both locations must be secluded, tranquil, and easily accessible for your cat. If one place is excellent while the other is too noisy or not private enough, cats will fight over the same litter box. Since cats prefer quieter environments, having two litter boxes will defeat the purpose.

What about a bonded pair of cats?

While partnered cats are far more inclined to share food, toys, and attention, sharing a litter box is a different story. There may not be the same geographical concerns (though they are still feasible), but hygiene considerations still apply. There will be an accumulation of waste that is impossible to handle, resulting in potential health problems for your cats.

Final Thoughts

If you have more than one cat, you should adhere to the golden rule of litterboxes: one litterbox per cat plus one extra. Cats cannot share a litter box for behavioral and health reasons, and they will be happier and healthier if they have their own litter box in a private, quiet location.
