Hi we have a male veiled chameleon who is approximately 8-9 months old. For the past several days, almost a week, he has been sitting on the very bottom of the cage not moving, not eating or drinking. He will move if I clean his cage but only slightly. I was worried something was wrong with his legs so I picked him up and put him on top on a branch and he sat there for a bit then went back to the bottom. The cage isn’t too hot or cold, he’s in a large open air ReptiBreeze cage. I’m new to chameleons and have no idea what’s wrong. Any thoughts?
