Hello about 4 days ago my Ball Python went from his normal cheery inquisitive self, to always hiding in his hide, or just outside. If i go to pick him up while he's outside his hide he balls up really tight and hisses. I can't tell if he is starting to shed or not so I was wondering if there was anything that would cause a literal overnight change in behavior.
