In case anyone also has a mouse eater: I got some mouse bedding at my local reptile store, put it in a small container and placed it in her tub. I waited a couple minutes and went back to check if she was sticking her head out of the hide, waiting to ambush a rodent. From there, I dropped a live small rat into the tub, she immediately took it and ate it. She also took a f/t weaned rat, so using live wasn't necessary. Next week it's on to a medium.
