I have always had several cats (&dogs) & people cannot believe my house doesn't smell. Hello!! Cats don't smell. They are very clean unless they are ill & can't clean themselves. It is the dirty litter box their owners don't keep clean that stinks up the house, and then the cats will start going on the dirty clothes (or wherever) you never pick up because their litter box is dirty. Pardon my highjacking, but man this is something that really gets to me.
