I have a leopard tortoise that is about 6 months old. She has a little bathing area and the right heat and everything in her tank but just the last 2 days her head seems a little dry and lighter colored on one side. Can I use a little oil free natual baby lotion or something else for pets specifically that would hydrate and help her heal or be better off? Its not peeling or anytihng, just a little dry. Is that normal btw?
