A vampire is not a human. It was a human before, but now, an immortal. So, vampires feed on blood to quench their thirst. It gives them strength, like how food gives us energy. Vampires don't eat food. Human food tastes gross to them. They can feed on either human or animal blood. Human blood is better tasting, but for civilized vampires, they will choose to feed on animal blood. Blood has a nice smell to them. When vampires feed on a lot of blood, they will be able to ignore the scent of blood in the air, and they will have golden eyes. If they're thirsty, they'll have black eyes or red eyes.
