also fat cats can't clean themselves and odds are if she's obese her animals are also obese so that's just an extra layer of possible feces to be aware of.  i had a 400lb coworker who was always a bag of snot sneezing all over everything and just being in his presence used to make me sick CONSTANTLY.  she could have dripped snot in the brownies!!!! UGH.  I hope you feel better and i hope she gets fired soon
