I have a 21 year old cat, he's been to the vets twice in his life, still has all his own teeth and is still the king of his territory, he also keeps 2 young dogs in line here at home. I do fear that he's starting to lose it though as this year he hasn't bought me any squirrels as a present, it used to be 1a week!. Cats are cool but I'm more a dog person in all honesty.
