IMO I would feed a variety of things... and even try experimenting a bit! They seem to like food that is "on its way" which makes it a good candidate for old refrigerator goodies...lol! I would forget about the calcium supplements etc and just allow access to ample oak mulch... not fresh, not rotten, not dry, not really wet... a happy medium

Also, oak leaves make good cover for them as well. They can actually live off oak mulch as a staple, it is exellent for the development of their exoskeleton. Some people say that it doesnt matter, but I would suggest washing any veggies well to get rid of pesticides, after all they were designed to kill the bugs
LOL - in experimenting, I found my millies seem to enjoy rabbitt pellets that had been soaked in water... go figure!
You will love the little, er big guys, they make awesome pets! :thumbsup:
