Pillbugs, rollypollies, whatever you want to call 'em, would they work for a leopard frog? There's been a population explosion around here, and most are HUGE! Since they're readily available, numerous, and I read that their shells are made of calcium instead of chitin (sp?), would they be just as good, or better, than crickets? We have a colony in the garden that we feed well, so they're already "gutloaded".
