If you saw my recent article about Cat Whiskers, then you know that whiskers play an important role in the lives of cats. 

However, cats are not the only animals with whiskers and as a matter of fact most mammals have them. 

That is, most mammals have them except for humans. 

I know, my grandpa always called his facial hair whiskers too, but those are just hairs, not true whiskers. 

Check out this SciShow video to learn more about the role of whiskers in the animal kingdom and find out why humans don't have them.
