So my panther chameleon has this habit of becoming hyper about two hours before his lights turn off. He climbs all over his cage, mostly on the ceiling. I first thought that he wanted out to explore, but when I open the cage door, he retreats to the back for a bit and comes back, but never climbing out. He just comes really close. He is my first chameleon, so I'm not entirely familiar with their behavior yet. Can someone explain this to me?
