My Chameleon will only drink water from a spray bottle. Is that normal? When he is thirsty, he goes to a particular vine and waits for me to open the cage. When I point the spray nozzle towards his closed mouth, he opens his mouth and I spray water into it. Then he walks away. Has any one had this experience? He is healthy, loves meals worms and crickets. He is a Blue-bar Panther, predominately colored red.
