Mine's 11 or so. Shows no signs of slowing down yet. No cat has ever lived a more carefree life than mine. He goes where he wants, sleeps where he wants, always has food, gets his flea & tick treatments regularly. He's still very spry and athletic. He's a happy, healthy cat. When it's his turn to go, I know that he had a good, happy life. Never spent a day in misery. I couldn't bear the thought.
