There will be lots of fluffy white cats to throw up fur balls to the bad guys when they attack. Even their furs could be distracting enough for the bad guys. The bad guys would even start to sneeze as there are too many furs falling down.
Other type of cats should be the Siamese cats as they are fierce. When they look at you in the eye, it means war. As cats have sharp teeth and claws, that would be the next best thing to attack the bad guys.
