Mine are hibernated in the fridge. The process of preparing them is easy: about 12-16 days before you plan on hibernating, take them off of feeding. Soak them in warm water every other day up to the day you put them in for hibernation, to make sure they have no food left in their system. I usually hibernate mine for 6-8 weeks.
