I have a 19 1/2 year old male Mane Coon Cat. He is in great health, I think. His last blood work was May 05' and everything was fine. I little heart murmer. Now my problem is his tail. He has a tail that stands tall and looks like a question mark. Sometimes he would put it down by now I see for the last 3 days or so that it isn't up at all. He has been walking slow for a while but still jumps on and off my bed. Do you think this is an indication of anything or am I just looking too closely at my cat? I am so worried about his age that I watch everything he does. What do you think?
