My cat is peeing on my bed whenever I am gone overnight. I spend all day with her when I am not at school or work (mon-sat) and I spend sun at my boyfriends house. And everytime I get back on monday she has peed. It is most likely due to stress- she is confined to the downstairs with one other cat due to her aggression with the others. I got her fish to watch and entertain her while i am gone but she is still peeing. I have put so much time and money into keeping her happy but I have run out of ideas. What do I do (she is my baby- getting rid of her is not an option)?
