cats

Let's say an average Scottish military member is a level 2 warrior with +1 in each physical ability score, Weapon Focus, 2 ranks in Perception, and leather armor.

13 HP, 13 AC, +3 to hit, 1d10 damage, +5 Perception.

50% chance to hit a cat, same 95% kill. Only now the cat has to make 14 hits, and each is only a 60% chance to hit. The cat's advantage is still 3 attacks per round.

I'm running a quick Python script to simulate this, rolling proper damage. Survey says a cat has ~1.3% chance to kill a soldier. Since all the cat's damage output is nonlethal, we can assume it heals between fights. Bump that down to 1.2% after factoring in a 10% chance that the soldier sees the cat coming and shoots it from afar.

That means an average soldier should be able to kill ~83 cats before going down. Scotland doesn't stand a chance.
