20 years is a good old age, mine is coming on for 12 years and is more like a dog than a cat. All my mates absolutely love him because he's so friendly and sure of himself, never lashes out at anyone and allows kids to pull and poke him without getting the least bit upset, in fact he prefers being patted rather than stroked the wierd creature. I often wonder what i'll do when the time comes and it breaks my heart when I think about as I know i'll be in absolute bits but I know if he lasts 20 years i'll be more than made up.
