Mr. Kitty was found abandoned as a kitten. As soon as he moved into his new home, he found a boy who soon became his best hooman friend for the next 17 years. Today Mr. Kitty is 17 years old, but he always has a heart like a kitten. He has watched his hooman buddy grow from a boy to a man. We hope their friendship lives on for many many more years!
