I have an 11 month old male veiled chameleon. He used to eat crickets right out of my hand but in the last few weeks he has slowly stopped eating and drinking. The last 2 weeks he has gotten worse still. He became a little sluggish and started falling. The local pet store owner suggested using calcium drops and also giving him water with the dropper. He appeared to start doing better but in the last few days got worse. His color is bright and he is more active but he will no longer open his mouth for even water. He moves around but won't open his eyes. He has no interest in any type of food or water. Any suggestions?
