She isn't going to die if her husbandry is right and she's healthy.
But stop offering food more than once a week. Offer once a week. If she takes, great. If she doesn't, take it out and try again a week later. Offering more than that just stresses them out and makes them less likely to eat. The striking your seeing now is defensive - ie: you're annoying her with the rodent and she just wants it out of her face. that's NOT going to make her want to eat.
