I have two cats that always got along. Recently one if my cars was attacked by a dog and we had to amputate one of his hind legs. Since then, my cats have begun completely ingnoring each other. This isn't the problem. The problem is my female cat has refused to use the litter box. She's chosen to use a corner of the living room, no matter how many times we clean it. My now handicapped cat pees on bathroom rugs, clothes in laundry baskets, etc. even though the cat box is clean. My husband is at the point he wants to get rid of both of them. I don't know what to do, but this can't keep happening. My male (handicapped) cat I've had for ten years and spend a lot of money saving him after his attack. My female cat I rescued from a shelter about 5 years. Help me please?
