The vet visit went well. The Veterinarian stated he looked healthy and wasn't concerned about his at times dark appearance. He stated that the chameleon was likely cold and that I should attempt to heat the cage a little more. He recommended we change the bulb or add an insulator to the cage. The fecal test did reveal pinworms and we received medication for that. I bought a temp gun and will keep a log of temps to see where we're trending.
