I am a sympathetic person, if someone is in pain, I feel that pain. This translates into me being a sympathetic vomiter. I can't help it, it runs in my family. When I was little I remember my mom was sick in bed with a cold and I saw a bowl of vomit beside her bed. That sent me blowing chunks immediately, and then- sympathetic mom, barfed all over herself. Seriously it was barf everywhere. And removing the barfed on clothes, you can bet that made everyone dry heave (we were all barfed out at that point thankfully).
Hopefully you have a strong stomach to watch BWE.tv's list of the top 11 cat barf videos of all time.
