I saw pics of it eating rat pups. It ate okay. I did some searching on the forum and pulled up this thread:

I know that Eugene Bissett had a female (I can't recalled what he called his, not derma though - but same thing) and she died this past fall. He talked about her on Reptile Radio a few times, and he did say that her skin tore easily when feeding so he had to be careful of prey size, and had to feed her pre-killed.

I believe I remember the original owner of the male derma did breed him and produced a clutch (or more) of normal appearing babies and was at one point offering them for sale as het derma. My memory isn't what it used to be, so I may have my facts a bit off, but that's what I recall from a year or two ago.
Again not sure how either Eugene's or the original male died, but I'm very interested to know- or if anyone ever tried to breed those hets together.
