That's a long-lived kitty! :) My cousin had one that got up to 12-16, I think. Mine lived to about 10.
One of my backpacking friends had a female cat that lived to 26 years.
You may not have been here when I posted about my kitty at mom's house. Got her in 1987, and she was already 6 months old. Who knows how old she will live to be. She is my "old lady" who can't be bothered with the young-uns (i.e. the other two cats at mom's house). When I went to visit her about a month ago, she was all forlorn and neglected looking. She had quit grooming herself, has a clubbed foot that prolly happened while jumping down from a tree and healed badly, and is blind out of one eye. I joke about her name, "B.C." cuz it is such a versatile name for her. Originally, she was named, Black Red Oak Baby Cat. I shortened it to Baby Cat, and then to B.C. It has stood for Beautiful Cat, black cat, baby cat, best cat, bad cat, blind cat, and most recently, bolemic cat. Yes, Bolemic Cat. She is nothing but skin and bones these days either because of her urping up all the time. Anyway, all that said, I went over there a couple-or-three weeks ago and took with me a wire brush, some cat-bath washcloths, and a new toy for her. You wouldn't believe what a difference brushing her made. She is a new cat. She has resumed grooming, she plays with her toy, and looks 100% better. Not sure I can do anything about her urping up all the time. Never heard of a pet having an eating disorder before, but I suppose it happens.
