I usually buy around 2-3 dozen at a time. I have 13 mouths to feed. I just keep them in the original bag the pet store puts them in. I add a couple of empty cardboard toilet rolls so they have something to hide and crawl on. Usually add a few pieces of good quality dog food and a slice of carrot for mositure. This keeps a high percentage alive for 3-5 days. Usually they are gone by then anyway because everybody likes to eat you know.
