A lot of the breeders have far more females than males, so when they say some of their girls are picky its because they have more of them. I would worry more about the males going on long fasts, but I am not an expert.

I got mine the "wrong way", on impulse at a pet shop (well I had wanted one years earlier but was too freaked out over the feeding issues). I think she is female and she wolfs down a f/t mouse regularly with no problem. I have no idea what she was fed before, she is c/h so I would guess live, but she eats like a little pig (no zombie dance needed) and I am grateful.
