Back in February I bought 2 baby ball pythons from a reptile expo, the female I bought shed about three weeks after I got her. Since then neither of them have shed, the temp is right and the humditiy and both eat once a week does anyone have any suggestions on what more I can do? They both eat rat pups and the female will be 1 on 9/30 and the male on 11/18, I'm getting very worried about the lack of sheding.
