My cat throws up for attention. It’s one of the most annoying things he does! If he doesn’t get attention or food in the instant he wants it he meows

My cat was using the cupboard door where his food was for the same reason. I more or less ignored him and he gave up. He would try to open door and it would slam shut bc he couldn't get his paw in fast enough to keep it open. The slamming was his signal that he wanted attention or food. He's not starving.
