My cat has a bad habit of drinking out of water glasses. So I never drink out of a glass that has been left unattended, knowing that she has probably taken a sip from it. Well I thought I was taking a sip of my fresh water (the glass i had just gotten)....but i accidentally drank from one that had been sitting there about 3 days and I'm sure she had drank out of it. I took a big gulp and it tasted funny. What do I do?
