The rule of thumb for the number of litter boxes you should have is the number of cats in your home plus one. You’ll truly have a happier cat if you follow that advice. No cat enjoys using a dirty “toilet.” But what if you live in a small apartment or have a larger space but truly have no room for a second litter box?
Simple. Just empty the box you have and wash it with hot, soapy water twice a week instead of once, as the advice usually goes. It’s a bit of a pain but solves the problem. Your fastidious cat will feel so much more relaxed — and less likely to develop litter box aversion.
