Funny-Face has the strangest way of getting a drink- I have his dishes elevated to his chest level because he is 18 years old and just isn’t as flexible as he was when he was younger, but anyway, he has to circle his water bowl at least four times, then he will stick his face over the bowl and howl like his best friend just died.  He cannot get a drink of water without circling and howling first.  He does have CRF and I am wondering if this is somehow related to that. I check his mouth and throat for sores, but don’t see any.  He also howls at nothing.  I’ve caught him standing between my nightstand and bed, howling at the wall.  I can get him to stop by walking into the room where he is and ask him “whats up?” Then he chirps at me and follows me around.  Is howling in weird places for no reason a sign for senility in cats?  He isn’t very alert either...I can sneak up behind him without him knowing I’m there.
