I can relate to cat hair and fur balls too! I don't mind at all if my pets are sick because I luvs them and they're my kitts. I can pick out the fur, or clean up the mess in the litter box. But if it were children or people getting sick....
. I'd woof my cookies.
My twin sinister is hilarious. She can't stand the sight of a furball. And it's just fur, and maybe some food, or grass, and um, tummy juices. But all natural and identifiable. Unlike human stuff. Ewww. I even hate it when I get sick.
Anything found in food from a restaurant.. blehhhhh! Can't. Swallow. Any. More. Particularly a hair or a bug.
