Kitten Snot

Nice thread title eh?

My little girl has this annoying problem. the constantly has a black line on each side of her nose. It's kittenboogers. It doesn't affect her, but it drives me crazy. I have to wipe it away a couple times per day. She lets me but i know it has to hurt because it's all crusty.

Is there something I'm feeding her etc that could be causing this?

my cat has that to but he has been sneezing for 2 weeks now we took him to the vet cause his nose is bleeding to
he has a respiratory infection

use a damp towel
