I recently got a variant of Fischers chameleon. Everything is going smoothly except my new friend keeps waking up earlier and earlier. I leave ambient light from outside in the room and leave his lamps on during the day to create the best day night cycle I can. The only problem is he will get up earlier and earlier every day. The first night I had him he got up at 4am and now he is getting up at 2am. This wouldn’t be an issue but he scratches at his screen until I turn the lights on for him to spare his claws. So I guess my question is why is he doing this and whats the best course of action to getting him an appropriate sleep cycle?
