She wasn't doing so hot eating-wise when I got her. I ended up contacting the breeder and altering my husbandry to where she was at before the move, and it still didn't happen for me. It ended up being that she'll only take live mice. I'm thinking it's a winter trend (kind of her version of going off feed), because the breeders mentioned that she tends to do this during the cooler months. Best of luck with your Pastel though! Once you get them going, they don't look back!
