Why Won’t my Cat Use the Litter Box?

There are a couple of reasons why cats won’t use the litterbox. The first reason is cleanliness. If the litter box is very dirty, the cat won’t use it. Cat are very clean by nature and a dirty litterbox offends them! If the cat has never used a litterbox before, it will have to be taught, especially if it’s a cat that is used to going outdoors.
