So 6 months ago my 5 year old male cat had a blocked bladder and after a few days in the hospital with a cathedar is home now. And has been feeling better. Occasionally peeing on his cat bed or on my shoes. I went on vacation last week and when i returned he came on the bed crying at 5 am well I was not ready to get up so I played with him for a few and tried to go back to sleep, next thing i know there is a warm liquid running down my arm, I look up and he is standing at the top of my pillow peeing on me. Two nights later after washing all the blankets and pillows he does it again. I'm locking him out tonight, is he mad at me for going away what? He doesn't have any of the other symptoms he did before. I'm going to lock him in the bathroom tonight does he need another trip to the vet?
