so i just got my chameleon and i love him. super fun to have around. but i noticed him yawn a few times today. then he left his mouth open for about 8 seconds or so. i thought he was over heating so i turned his heat bulb off for a little while. is this from it being to hot? or is it him starting his shedding process? i do see signs of him starting to shed. rubbing on the plants and wood.
