I have a male veiled chameleon. I am honestly not sure how old he is but I am guessing around 1 year. I will post a picture so maybe someone will know. He always wants to eat. I feed him around 10 crickets and 10 mealworms everyday. After its gone he will stare a hole through me and then go into his hunting mode. Usually I will put a couple extra crickets in and i wont even be out of his terrarium before he already starts snagging the crickets up. I don't want to over feed him because im sure that could be harmful too.
