I've actually kept crickets (as well as other insects) several times. If you can get a small terrarium with a live plant they do even better. It's not too expensive either. A small travel one from your local pet store is fine, and it gives them more room to play, and seems to help them live a longer. Just be careful with a set up that has dirt that any snacks you give don't mold, it can over take the terrarium and the cricket
