In the Middle Ages, cats were not very popular because of their association with witchcraft and black magic. Superstitions about cats, some of them current today, date back to this period. Fisherman’s wives believed keeping a black cat in your home meant your husband would always return from the sea. In the 9th century, King Henry I of Saxony decreed that the fine for killing a cat should be sixty bushels of corn.
There are still people who believe that the cat is a reincarnation of the devil and regard it as bad luck.
