How did cats get whiskers?

Cats are born with their whiskers. They would probably be kind of "blind" without them. The whiskers on the side of their heads are the width of their body. The whiskers on top of their head are how tall they are. They use them to see if they can fit through spaces or not. They are essential to cats, so never try to cut your cat's whiskers. This can harm them and make it way more difficult for them to tell how big a space is. This could result in them getting stuck or even hurt.
