Another thing to ask is if the store where you buy feeders will euthanize your feeder for you. It means you need to get home and feed it without dilly dallying too much, but if they do euthanize, they know how to do it quickly and painlessly for you. =)

My reptile store will euthanize for you and even, if you like, put feeders in freezer-ready plastic pouches, one feeder per pouch, sealed and everything (not quite sure how they do that, some sort of plastic heat sealer maker thing).
