The other day when I hand fed my Cham, he ate the cricket right out of my hand, but today I tried to hand feed a mealworm, he puffed up, hissed at me, and tried to bite me, anyone have a guess at what's going on?
Were you wearing something bright that he may not have liked? They can be funny with colours! My friend visited a while ago and she was wearing a chameleon t shirt and Tommy showed his dislike and puffed up at her!
