Try a change of food. If she was eating rats, try mice. If she was eating live, try frozen. Believe it or not, I have a snake that has never eaten F/T (he is probably 4 years old). He was my last F/T hold out. Wouldn't touch warmed up rats or warmed up mice. What turned him was a thawed but still cold mouse. I can't say why but it worked. Sometimes change just spurs them to eat.
