Vampire Association with Bats is very recent, in most of the Old World Vampirism was associated with Owls which is why the Latin word for Owl is also for Vampire, Strix, which is where you get Strigoi/Strigoaica/Strigoica, Strigun, and various other names for Vampires in Europe, Also Werewolves were historically either a vampire or witch in wolf form, and a witch was a living vampire.
