My kitty (he is one) will pee right ouside the litter box, but never in the litter box. It is super clean and never dirty. As soon as our other kitty does anything in it, I clean it in hopes that he will use it, but it never works. I have washed it down and used different litters and scoops. Nothing is working. He never pees on carpets or mats or furniture, just right outside the box. . . .inches away. . .occassionally while looking right at me!! Any thoughts from anyone?
