Some people will say no they won't starve themselves, I believe otherwise after having my picky white live mouse only eater!! She went 2 months as a hatchling when I first got her because people said wait her out, she'll eat. Well she was loosing weight noticeably so I finally went with live and never looked back. Even now when my supplier of live was out I got all 5 f/t that week, she wanted nothing to do with it, the other 4 ate no problem.
That's why I started breeding my own
