What are the Halloween animals?

Most animals (such as bats, cats [usually black cats], wolves, Spiders, rats, crows and ravens, etc.) are associated with Halloween because they are either nocturnal, dark in color and therefore associated with death, or associated with legends and monsters (bats = vampires, black cats = the familiars of witches or even witches themselves, wolves = werewolves, and spiders are just plain creepy. Also, crows and ravens are associated with death.)
