They don't bite, I don't think they are able. They don't fly, no wings. They eat carrots an crushed cat food. My adults cost me $15 each and if I do sell any babies I'll probably do $5 a piece because 15 is for crazy roachie lovers who are willing to pay that much, there aren't many of us. They do climb and run, except for Reqiem who as a broken foot. If they are hand raised they are less likely to make hissing noises or to run from people.
