Today i noticed my Mali under his hiding spot doing something that I've never seen before. He was throbing his throat like a toad (which he does do alot) BUT he was also holding his mouth open really wide. He did this three times in fives mintues. He didn't act aggressive or as if he was doing this at me and he wasn't head bobbing. Really, I'm not sure if this is a guy or a girl, I guy I think so maybe this is a mating thing. He's about 2 y/o. Other than that I can't think of anything. Nothing has changed, he is eating normal (today he ate a few crickets...his monthly treat) temps are the same, behavior is otherwise normal. Sooo, any ideas? please!
