it could be the switch .. a female of mine was on live i switched her to f/t she took a couple then she was refusing .. she didnt eat for 2 weeks then i said f it gave her live and it was on .. try dropping a live in there .. sometimes its just the snake being stubborn but shes been my only one that acts like that when i got her i feed her live .. now when i get new hatchs i go right to f/t and straight to rat pups and its been working
