How do the vampire get blood?

Vampires are legendary creatures and do not exist in the real world. Vampire BATS, however, are smaller than a teacup and their only diet is blood. Their usual victims are sleeping cattle and horses. Vampire bats do not "suck" blood from their victims but, after puncturing the skin, actually lap up the flowing blood with their tongues. The bats' saliva prevents the blood from clotting. These tiny bats never remove enough blood to harm their victims but the bites can cause infections and disease if not treated by a doctor.
