How old is she? Once my females mature if I'm not planning on breeding them then I put them on a two week schedule. If they refuse I offer weekly until they eat again, then I don't offer another rat for two weeks. Many of them self-regulate to eating every 3-4 weeks.
You could also offer a smaller rat at each feeding, especially since you feed live and your snake is refusing meals, as otherwise the rat could eventually grow larger than your snake should eat.
Or do what I did and get a boa to dispose of any leftovers.![]()
