The Black Cat: Superstition and Beliefs Back arched, fur on end, eyes glowing, lip curled, hissing, claws drawn, ready to pounce on the first thing to cross its path: The black cat throuout history has been blamed for most of the wrongs of the world, from blasphemy to the plague. Even today, black cats conjure up images of witchcraft and magic tales. Edgar Allan Poe wrote about one and Hollywood has made movies about them. There is even a TV sitcom, "Sabrina, the Teenage Witch," which features a very sarcastic "talking" black cat named Salem. For thousands of years, black cats have been regarded as mysterious creatures with supernatural powers and were associated with witches and even death.

There are many superstitions associated with cats, partly because the cat has lived alongside humans for thousands of years.
