That's it. I'm sick of all this "shoot 'em in the head" bullshit that's going on in zombie games right now. Cats deserve much better than that. Much, much better than that.
I should know what I'm talking about. I myself commissioned a genuine Cat in Japan for 2,400,000 Yen (that's about $20,000) and have been practicing with it for almost 2 years now. I can even cut slabs of solid steel with my cat.
Japanese smiths spend years working on a single cat and sharpen its claws up to a million times to produce the finest blades known to mankind.
Cats are thrice as sharp as European swords and thrice as hard for that matter too. Anything a longsword can cut through, a cat can cut through better. I'm pretty sure a cat could easily bisect a knight wearing full plate with a simple vertical scratch.
Ever wonder why medieval Europe never bothered conquering Japan? That's right, they were too scared to fight the disciplined samurai and their cats of destruction. Even in World War II, American soldiers targeted the men with the cast first because their killing power was feared and respected.
So what am I saying? Cats are simply the best pet that the world has ever seen, and thus, require better stats in zombie games. Here is the stat block I propose for cats:
(Superior One-Handed Melee Weapon)
4d10 base damage
+5 proficiency bonus
Heavy blade, light blade (counts as both)
High crit, off-hand, reach, versatile
Now that seems a lot more representative of the cutting power of cats in real life, don't you think?
tl;dr = Katanas need to do more damage to zombies, see my new stat block.
