My chameleon had Metabolic Bone Disease when I bought him for very cheap from a local pet store. I have been treating him for several weeks now. He continues to get better and better everyday, but I think one of the biggest problems is that he has a curved back now. His back was never broken, but it appears that the soft bones hardened that way and I don't know what to do. It's possible that he just needs more time to recover. Help me please!?
