My beloved Maine Coon cat has started pooping around my house with increasing frequency. She is three years old and this has just become a problem in the past few weeks. Prior to this, she would occasionally poop around the house but this is happening a few times weekly. We have not changed the brand of litter and her box is cleaned regularly. Yesterday, I found poop on my bedroom floor and it was obvious that she urinated as well. I cleaned the wood but I know that cat urine is a pervasive smell so I am worried that this will become a habit with her. She does not do it in the same places consistently. I don't want to turn her into an outdoor cat but I am completely frustrated. Any suggestions?
