So the gut busted? Aslong as she got the rat down I don't think there should be a problem. And if she regurges, all it'll do is empty out her stomach acids so she'll have to replenish her acids. Basically if she regurges, I'd just clean the mess, and give her till next week to eat. Or if you want to feed her soon, I'd give her a day or two to replenish the acids first.
