Well I dropped him off early this morning, and just got the call that the procedure was a success. They also discovered that he had a splitered molar, which was most likely the cause of the majority of discomfort. They removed it, and filed the teeth down that had points. I will be picking him up later today, they said he's awake and bouncing around already. They're going to give me some liquid food to be syringe fed, as well as some antibiotics, and they said everything was looking good. I'll keep you all posted as he recovers. As for hay/lava rock, yes I do keep them available at all times, mostly timothy and some alfalfa changed regularly, as well as filtered water, lava rock and a salt lick. However I let a friend take care of him for a few weeks while I was away, and they said they forgot to feed him hay. It's doubtful that the problem could develop in that short amount of time though. They said it was probably a genetic problem vs a care situation, as most of these cases are (according to them). Let's just hope the problem doesn't return in the near future. Once again, thank you for the kind words and your concern, I'll let you know how things are going later on.
