i knew a jack russell once who had one eye ( he came back one night with it missing and his face a shredded mess) and a huge scar running down his chest from a car accident,he was the most ugly aggressive dog ive ever come across,if it moved however big it was he wanted to kill it ,anyway on the farm were he lived was a large population of feral cats and he would kill them on sight ,even a large tom he would savage to death and come back home with rips in his ears and great lumps of skin shredded of his face and back looking like hed been put through a mincer ,as for the law concerning cats i
