Ok I so I came home from work and went to check on my Cham and he was sleeping six inches from the bottom all fine and dandy. I opened up his enclosure to spray and I bumped the vine he was in he woke up looked at me went to move and fell a couple inches caught himself puffed up real big then fell again continued to puff up and hiss at me. I left him be for a second he settled down. He started climbing the side as soon as I moved he puffed up again fell on his side from about two inches up stayed on his side and hissed at me. Is this some sort of defense mecenisum, or is something wrong with him?
