My Susie is 19 years old and while she still eats well and has no potty problems, she often wanders a short distance away from her bed and stands stareing at a wall and HOWLS. Once she realizes I or my husband is in the room she stops and goes back to her bed. We have other felines who basically ignore her, although the kittens like to lay on her bed near her. Susie is deaf and has been for years, I am wondering if that is adding to her confusion. Any ideas? She is so old and doesn't appear to have any problems or be in any pain, and going to the vet would probably be so upsetting to her, I do not want to go unless she really needs to.
