you don't have to have your leos go through hibernation since they're captive... but i guess if they already started, you can feed well gutloaded meal worms, silk worms, and super worms. also, you can give a treat of ONE wax worm a week (helps them get some fat back, but they're addicting). if your leos are ADULTS, then one pinky mouse can be given once a month... i think it's because they're high in fat. also, make sure you're getting your pinkies from someone good because pinkies can sometimes cause some bacterial build up or internal parasites. you can feed these live because leos love to hunt and attack their prey.
