Weird thing...

[CasparChameleon]

When your cham gets angry they puff up, right? Caspar was the same way until a week ago. He started doing this weird thing when he gets angry, he sucks in until his ribs jut out... it's super freaky. I looked up stuff about this and some people say it's normal? I just took that for an answer until I noticed yesterday that he sucks in on his right side and puffs up on his left. Can anyone help me find a reason for this?

Update: He keeps opening his mouth like he's hissing, but he's not...

He could be too warm, sometimes chameleons will open their mouth if the temperature is too hot.

When he sucks it in is get getting taller. Mine will suck it in like that to flatten himself making him look bigger from the side. Mine will also open his mouth when I get to close without hissing, he is making him self ready to bite.
