Our cat history is..
Betty, 1st cat, moggy, now 19 and a half &still going strong
Karina, white chinchilla Persian, 17, lost to mouth cancer (just before we took over the world)
Lola, tortoiseshell , 5, liver cancer, 2weeks after big deer hound x greyhound lost to same thing
Marley, big black cat, 4, went out never came back, miss him
I think anything last 18 is amazing, Betty is a bit senile these days, I'm sure she's decided she's a dog, but hey, dogs are good
