I have a green iguana not very old...but very mean. I can't handle him at all and he freaks out any time any one goes near his cage. I don't know what to do. I do not want to get rid of him because he is mean. I just wouldn't know what to do with a 6-7ft animal that is horribly mean. Any suggestions on how to get him/her to calm down? Or maybe why so mean?
