I've been feeding Lilly two mice a week, b/c the only place you can get mice or rats here is petco, and for rats, all they have is fully grown medium and large rats. =/ She won't eat f/t and other wise I would have to go to the next decent sized town...at least an hour away. It's not really possible to keep the mice that long to fatten them up, but it doesn't actually hurt to feed two mice a feeding does it? I know it's not ideal, but it's not harmful, right?
