Velvet is...a little different with hunger. Because all of her nourishment comes from blood, she doesn't actually need to eat food at all. She just does, because it tastes good. So if it doesn't taste good, she just won't eat it.
Until you pass out

"See? This is the problem, right here! I won't drink more that two pints tops from a person, I think I know enough about the circulatory system after seven centuries to avoid hypovolemic shock! This is prejudice!"
