I bought radar a new bed for at home when he doesn't want to sit in the chair with me. He is 11 weeks old and doing fantastic with housetraining. But he peed his bed after being inside for 10 minutes after his potty break. We have 2 male cats that most likely sniffed and walked on his bed today while he was visiting grandma and grandpa. Is he just marking showing the cats they can't be on it? What do I do?
