In 1233 AD, ninth-century Pope Gregory nailed the last nail on the coffin of a black cat, when he declared the black cat an incarnation of the devil. With this statement, Christians tracked down black cats and burned them alive at festivals as punishment for their demonic incarnations. Things were so bad that in the 14th century, cats were nearly extinct in some parts of Europe.
Centuries later, the idea that black cats are associated with ghosts was naturally conceived, leaving black cats seen as witches. According to superstitious people, black cats are believed to be witches in disguise. Others claim that black cats may actually become witches after being a member of the wizarding world for seven years in a row. In the 16th and 17th centuries, anyone who owned a black cat was enough to be considered a witch and sentenced to death.
