Today I noticed my cham exhibiting some strange behavior. He was sitting on one of his branches and he had puffed himself all out and had his chin pushed way out and was rocking back and forth. Then he would do something like a shiver. He then opened his mouth in a yawn and then just kind of walked away. His temps are fine (mid 80's ambient to mid 90's basking), so I'm not sure what the whole shivering thing was. Any ideas would be great.
