I have two cats -- and all signs suggest that they are two happy cats.
This is a good thing, as "not happy" cats are -- well -- "not fun".
One thing that keeps kitties happy is a good, tidy litter box. Sometimes, that space may feel like a cat's "home" -- and you will want your cat to feel "at home" in the litter box more than any other place in your house. It is not fun when a cat feels "at home" on -- say -- the living room carpet.
The litter box options in this article can help you help your cat feel comfortable when it is "potty time".
(Yes, bad puns are my affliction.)
