You have to picture this feline invasion of Scotland from a realistic perspective to fully understand the long-term strategic implications involved in the purge. Getting cats to engage in guerrilla warfare is like herding cats. The whiskered menace will obliterate every available source of food within the week, leading to complete systemic collapse and infighting. Morale will drop, fraggings will spike, and the kitty command structure will fall. Not to mention the strategic advantage yielded by humans tolerating small amounts of water on their feet and this being Scotland. I think the scots have a fair shot at this if they can ration resources.
