My new pastel was eating live mice when she was with her old owner and ive had her for nearly two weeks now btw so i let her settle in. and i want to wean her onto f/t rats. ive offered it to her twice now and im worried shes not gonna take unless i try something. but that something is wat i have no idea of haha. she will strike at it and even hit it but she wont constrict or eat it afterwards. any pointers?
