4 week old kittens bald patch by whisker please help!

Two of my kittens have a bald patch just on one side of their mouth by their whisker (both kittens have it in same exact spot) it gets slightly scabby and looks a little pink. They aren't scratching or anything. They are still nursing so I don't think it is a food allergy. I figured I would ask here before I took them to the vet. Thanks in advance for your replies!

With a little luck its their mom biting off their whiskers.   It happens sometimes. Its not dangerous.    Otherwise, I dont know.

But its good and wise you are letting your vet look at it.

Good luck!
