Just a reccomendation - our sweet kitty is a priss when it comes to his litterbox. If you come in the room he gets miffed - but when he was about a year old he went potty on the bed and Then did it again 3 days later. The vet gave me a Pheromone spray that you spray over the cleaned are and the cat will not smell himself there any more - As I recall it was pricey but - it has lasted quite a while and the problem stopped. Good luck - our boy is a doll except that he is a small boy who goes to the bathroom a lot and cannot stand his littebox to be slightly dirty. - but now he doesn't use the bed.
