If she'll take it I would try moving up a prey size. I'm keeping all my corns and my youngest king on the Munson plan and so far I've found that it works extremely well! I still have a couple of picky eaters but for the most part they will still eat just not off of the hemos, I just leave the mouse on a lid or something outside of their hide overnight and 9 times out of 10 they'll eat it. A couple of them are almost ready to move up to fuzzies . Let us know how it goes!
