Nice Rats, Nasty Rats: Maybe It's All in the Genes

I wouldn't mind having a tame silver fox at home, but no way would I ever want to raise rats and mice in my menagerie. Not even those cute guinea pigs - one look at those little furballs and my white rag hunter, Niko, will go charging into places he usually dares not tread on. It doesn't help that I sometimes get this urge to put my three-colored must-be-a-Manx-with-that-tail Tasuki on the hunt to test how much domesticity has repressed the killer's instinct in her.
