You'll get over it... I was SO grossed out I wanted to throw up when my perfect little angel Pixie did that for the first time.... She doesn't normally eat poo. In fact, she won't even go NEAR her own. I have to pick it up off her pad before she'll walk on it again... I don't know what it is about kitty "products" though. Poo, hairballs, vomit, whatever. She'll eat it.
It's still gross, but now I don't freak as much. I just pick her up, grab her toothbrush and give her a good brushing. About an hour after that she's back to licking my face.
