We went to the vet yesterday, hoping for surgical fix. No luck finding that, but the vet taped it and made a "splint" out of tape -- he's doing pretty well today. I took photos of the finished tape job yesterday, will post later. (Still recovering from flu, sorry).
Anyway, I think there's still hope for the little guy. Vet said to try leaving it for five days. He's actually getting around surprisingly well on it.
Fingers crossed.
