Hey everyone!! So I got a Ball Python recently and she currently has a medium sized hide, I noticed recently when she goes into it, the whole hide moves up and down with her adjusting. So my question is what size hide should I get for her?? I'm not quite sure on her weight honestly, I would check, but I just fed her. She is about 2ft long roughly and a little over 3 months old!! Any help is appreciated, thanks in advance!
