The easiest way to train cats to use cat litter is to let female cats or other adult cats carry it. Try using cat litter by showing cats that other cats use it. If there are no other cats at home, the owner will train by himself.

Male cats pay great attention to the sense of smell, which is especially obvious when male cats are in estrus. Male cats urinate everywhere when they are in estrus, marking their territory, giving off charm and attracting nearby female cats.
