I currently own a male California 50/50 kingsnake, about 9 months old. This is my first time owning a snake and after doing a bit of research I decided it was best to have him hibernate. I followed proper procedures for hibernation and it went well at first. He's was asleep for over 3 weeks but suddenly this week he woke up. He's been frantic and aggresive and I've tried feeding him but he refuses to eat. What should I do?
