I have two cats. At night I now keep my bedroom door shut. I never did this in the past so I know it's new for them, but it haa been a few months now. I am getting woken up several times at night now by them scratching and pushing on the door. It is mainly one over the other and he always runs to his good bowl. I don't give him any so that he thinks he can do this whenever he wants food, but it has been several weeks and no change. I have tried tape on the door, citrus spray, etc. any thoughts?
