My mom's one cat, Ashley, lived to be 23. She was healthy up to the end except for a tumor that developed on her skull. Other than that, she had no diabetes problems, no thyroid issues, nothing! She was spunky and funny, and raced around the house like a mad woman! She had been a stray, but we took her in when she was about 2-4 years old. Ashley was an indoor only kitty.

My cat when I had from when I was 5 years old was named Corvette. She was an indoor/outdoor kitty as we lived on a farm. Corvette passed away at the age of 21. That is a grand old age for a farm cat!
