If you have a lot of snakes, live prey is just too expensive, unless you breed your own. F/T is safer and cheaper. Im sure Ill still buy live for a picky eater here and there, but I am full on convert to F/T. Saturday is mass feed day for all snakes, and everyone is getting F/T. Those who won't eat F/T rats will get F/T ASFs. I am sooooo over spending $3+ on a dumb a** rat.
