That is indeed a fantastic age for a cat. My poor James was hit by a car and had a fractured pelvis when he was 4, the vet did a good job of fixing him up then and he had a nice life until the arthritus set in, in his pelvis, when he was 14. His kidneys had started to go, as they often do in cats at this age, and he was going a bit senile too. So it was kind to say goodbye when he was put to sleep. I wouldn't want him to suffer, and suffer is what he would have done if I didn't grasp the nettle and do one of the hardest things I have ever done and ask the vet for the lethal injection. Fellow ABers helped a great deal, you know who you are and I thank you all.
