Lately my Ball has been super lazy. She'll typically be all over the place at night, moving around, checking everything out and all.

(3/4 of her Vivarium sides are covered so she shouldn't be feeling anxious or trying to find somewhere to hide, considering I already have a hide for her.)

However lately, she's not been moving around, only to slither from laying next to her water bowl, then back to her hide to curl up again. She's only about a year old or so, I'm not entirely sure, but I'm worried maybe my husbandry isn't as good as it can be? Her temps do get colder at night, and I always try to keep her humidity between 50-70 percent while I try and build her a new enclousure myself. Or maybe it's close to shed time? I heard that can cause inactivity.
