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.
