Okay I know this sounds like it could be easily solved by a google search but I cant find anything that could actually help me. Recently my cat has started to spray in the house, he mostly does it underneath objects, under the recliner chairs, if I leave a drawer on my dresser open and stuff like that. It's not medical as he literally just got over a mild urinary problem (Mild infection mostly just needed more liquid) He has two litter boxes cleaned daily, multiple pheromone diffusers, and he is played and fed the same time everyday. Its just this week he has started spraying but for about the entire time Ive had him he has done the spray stance (back arched tail wiggling) but nothing came out and I didnt think anything about it. I dont think it is stress because he never looks stressed out when he does it he is just strolling under a chair then does it. Not sure if it is territorial as he never does it near windows. He also in general appears to mark stuff a lot with his cheeks, like marking a chair everytime he passes it but I dont know if thats related. He also is not an outdoor cat but he is allowed in the backyard if someone is sitting with him, could he be smelling stray cats outside then coming in to spray? Any advice on why he is doing this and how to stop it?
