Young pastel throwing up her food

[Kimmie]

So my young pastel, I got from my normal breeder Ed from Nederlands, have started to kill her prey and after a while throwing it up :/ this have gone on for around a month, she shed normal she dont look thin, she dont have RI, before this she ate normal close never said no to a meal.
I must say close all of my snakes are from E.C Reptiles and I never had a problem before.

Anyone have had this with any of their snakes?


Please help
