They suck blood, have ghoulish faces, live in dark caves and hollow trees, only come out at night ... and never transform into mysterious, seductive, well-dressed strangers with Transylvanian accents. But if you can look past all that, vampire bats have a certain charm.
Their diet is mostly blood, but they typically prefer to feed on cattle, goats or even birds. Human bites are rare — and entirely harmless. You'll hardly feel a thing.
