This is my buddy, Jungle Jack. He's definitely getting on in years—best guess is 18-19—but he's still doing fine for his age. Chronic kidney failure, chronic asthma, and not really anything else wrong with him.
He's the sweetest, cuddliest, snuggliest, friendliest cat I've ever met. I don't know what I'll do when he's gone, but it seems at present that it'll be a while (a year or so?) before I have to worry about that.
