My babies have never tried to bite me. Thanks for the good tip on distracting an ig, it helps me with my hatchling(who I got 3 days ago and seems to be more neurotic than the average hatchling).
My older baby ig, Khain is unusually sweet and intelligent. He's only been at my house a week, but is calm and will let anyone hold him but my ex(who ironically bought him for me as a christmas present) It took me only 3 or 4 times for me to teach him not to whip his tail at me. I said "NO!" in a loud, stern voice and gave him the iguana stink eye while I covered his tail with my hand. Then, I would go back talking to him in a soft voice and give him a treat 5 mins later. One unusual thing Khain does is most baby iguanas will freak out when you try to extricate them from their cage. Not him, he will let me scoop him right up. He will sit right on my shoulder or chest the whole time hes out, loves to be petted and will nap with me. Then, he will freak out on me(when I try putting him back in his cage) and try his best to make me keep him out of his cage, even by throwing his limbs out to make himself wider than the opening or jumping on top my head!
