Black is the color of cat that is commonly associated with witches. This association can be traced back to ancient times when cats were worshiped as sacred creatures in some cultures while others believed they were evil and associated with dark magic and witchcraft. In medieval Europe, cats were often associated with female witches and accused of being their familiar spirits. The black cat, in particular, was seen as a symbol of bad luck and often depicted as an accomplice to witchcraft, especially during the infamous witch hunts of the 16th and 17th centuries. Despite its negative connotations, black cats remain popular pets and are believed by some to bring good luck.
