Everyone knows a cat's calling card is its iconic, unmistakable, adorably triangular-shaped ears.
Think about it. When you draw a cat, you add pointy ears so everyone knows it's a cat and definitely not a dog; when you inevitably dress up as a cat for Halloween in college (hey, we've all been there), a pair of kitty ears is all you need for everyone to somehow know exactly what you're trying to be.
The ears truly maketh the cat. But what happens when a cat doesn't have any ears? What maketh the cat then?
