Yeah, I am wondering if he got his mouth caught in the inside edge somehow. That would explain why he couldn't get out (he had plenty of room otherwise), and why his mouth got infected (probably ripped it up trying to free himself, couldn't eat, and then got an infection). I might try to contact TTA to replace him, as I would rather go that route than inbreed (which would probably throw me only albinos, and I like variety). The trick with TTA, of course, is finding a way to contact him, LOL!
