So since last October my wife and I have had a problem with one of our cats peeing on our spare bed. We have three cats and just recently found out that it is our dominant alpha three year old male Liam. The first time we found it, it was a HUGE stain and since then it has been infrequent and much smaller. He still goes in his litter box all the time. I have not found any other stains he seems to only like peeing on the bed, and never in the same spot on the bed. We use Zero Odor which completely removes the smell and the stain each time, but he keeps peeing on the bed. He is a very relaxed laid back cat with a lot of affection to give and he can be hyper at times. We got him with his brother Finn and most of the time they get along but sometimes they fight. We recently got our third cat Luna when she was 4 months old, and Liam and Luna get along well and play every day. I should mention that he started peeing before we got Luna. I haven't seen any blood and it is really infrequent, about once a month or once every two months but it's becoming a pain in the neck! Can anyone help?
