I can't keep any herps with longevity. But when I was bashing on a house to remove rotten portions, a little hibernating alligator lizard rolled out. He was lucky I didn't smash him flat. I couldn't let him go, because he did not regain responsiveness while I was there. A skunk or raccoon would have eaten him the first night. So now I semi-willingly have a display lizard. I am not trying to tame him because I don't know his species' reaction to such an invaded lifestyle.
He is a 4 1/2 inch SVL adult now (not getting any bigger) and eats crickets. He is an unknown to me species from the hot western slopes of the Sierras. He is way smaller than any alligator lizard I've ever seen. He seems to be doing great. I can't see a way I can ever release him without putting him in severe danger of being eaten right away.
