they're alot cheaper than crickets when you breed your own, they don't die off like crickets, they don't smell like crickets, they aren't noisy like crickets, and they're alot healthier for your animals. I don't know about the other animals (yet), but my sav goes nuts over hissers, and we used to get lobster roaches for the beardie we had years ago as treats. I'll know soon as I just ordered a colony and should be here tommarow, once they start reproducing well we'll be cutting crickets out of the deal all together. I imagine they'll love em though.
