I did have the same thing happen to my '08 female a while back. She didn't eat for about a month and then just started eating again. If she is anywhere around the weight of my '08s then she is probably around 1000g which means she could go many months without eating and be perfectly fine. Also, if she is around 1000g she should be eating small rats, not adult mice.
Not necessarily, mine is terrified of small rats. So I feed her weanlings.
