Our four month old veiled chameleon who is relatively new into our care is eating dirt! We got him a ficus tree to be on when he is outside the enclosure and he has a new habit of climbing down the trunk to the pot where he shoots his tongue out and eats some dirt. He does it then tries to do it again but by the second attempt I usually have a hand blocking his view. He has also tried to eat dead leaves from the bonsai that we let him play on. He currently eats about 10 crickets a day along with some organic kale which he seems to love. Is this reason to worry or is he just exploring?
