In the past, I noticed my ball preferred to hide under the sheets of newspaper substrate rather than his 2 exo-terra hide caves (1 on cooler and 1 on warmer side of the enclosure) just prior his shed. However, for the past 2-3 weeks, he's always looking to hide under the newspaper rather than use the provided hides even though he hasn't gone blue. He's also been refusing feed the past approx. month and I haven't been able to get him to eat yet. The food refusal isn't something that's stressing me too much. I'm just wondering, considering that he seems to prefer hiding under the sheets of newspaper, should I even both keeping his 2 hide caves in the enclosure?
