I have recently experienced a lot of problems with my oldest, three year old, neutered male. He is literally peeing on our kitchen counters. He does this even when a freshly cleaned litter box is available. I'm not sure if this is a territorial issue, like he is urine marking, or if he is just seeking attention? Any solutions?
One important detail is that I've decided to keep him indoors only now. I'm thinking that he may be feeling frustrated or cooped up now that he can not go outside. Could this be causing him to act out?
