Hello. I've had a few concerns with my new Cham, Munch lately. It began with sleeping during the day, but we resolved that by keeping his nightlight off. He's been losing his balance lately and has fallen just a few times. Also, when a cricket comes by he gaps his mouth open, then closes it. Other than that he's a normal Cham. He eats well and has no other issues or red flags. We have a two week warranty on him, so if he needs to be brought to the veterinarian, it's on the house. Just please let me know if he needs veterinary attention. Thanks!
