I have a six month old panther Chameleon and I am trying to figure out this "eye popping" thing he does. He rubs his eye on one of the vines in his cage and then "pops" or bulges his eye. He doesn't do it alot but it freaks me out when he does it. It seems like each time he does it that he sheds in the next day or so. But I am not sure if this is just coincidence or what. He is very healthy and it doesn't look like it hurts him or anything. Does anyone know anything about this?
