So here is the deal. I have a veiled chameleon he is a very aggressive towards me. Whenever I put my hand in his cage He will hiss and puff up at me. Whenever he has is I pull my hand out immediately hoping that will help. I know he does not want to be handled so I want to find a way that can build his trust up with me. I've had him for over a year he has not been like this until about three or four months ago. If anybody can help or give me some information that might be useful please tell me.
