Have you tried to get her to eat two small instead of one?

A small live meal followed by a small dead meal?

I'd strongly recommend converting to dead regardless. It's just a good thing to do.

Also, here's some research

Frozen is the way to go.I put my rats in a bowl on top the heat lamp and get the rat up to about 95 degrees and its worked great.Tried at room temp and they wouldnt take but the warmer temp works good.I just switched 3 adults over to frozen at the 95 degree temp that wouldnt eat frozen prior to the hot meal.Hope this helps.

One more thing I forgot.I also use a pair of tongs to drag rat around if they dont take it just laying in the cage.Happy New Year!!!!!!!

Thanks, Louie! I'll try that, for sure. I know the mice were warmer than room temperature, but I guess I didn't think to guage what they were actually at :)

This is what I do when I feed my more difficult animals: Get the food item really hot! I thaw them out in the hottest water that comes out of the tap and then just prior to feeding I dump the old water and refill with HOT water. Dry off the food item really well with a paper towel. Then I basically toss up the substrate in the snake's encluse and make a lot of noise to get their attention. Drag the food item around on the substrate and do the "dead mouse/rat dance" until they take it.

I second almost all of what dark said," a lot of noise to get their attention" can also just as easily be a lot of vibration that freaks them out so they won't eat. Converting a stubborn feeder can be a real test of a keepers patience but it is definetly safer in the long run
