Hi, my sons leopard gecko is having trouble with her eyes . They seem to be sunken in a little. And she doesn't want to keep then open. When she does open them her pupil seems to be having trouble adjusting. It goes from big to small to big again like she can not focus her eyes. She had also lost some weight and doesn't want to eat. We live in Maryland so we use coconut fiber as bedding to keep humidity up. Could that be the problem ? Should I switch to paper towels? Or could it be stuck shed? I don't know what to do to help her without making things worse. Any suggestions?
