Why Are Black Cats Unlucky?

Black cats are considered unlucky in some cultures because of superstitious beliefs that have been passed down over time. These beliefs were especially prevalent in Europe and the Americas between the 14th and 18th centuries, when black cats were often implicated in witchcraft activities during witch hunts and trials. The association of black cats with witches (and bad luck) may stem from Western demonology, in which they were often depicted as familiars of witches. These familiars were believed to be low-ranking demons given to witches by the devil, and black cats—along with toads, dogs, and certain insects—were thought to be a common form these demons would take.

In many Western cultures, black cats signify bad luck much like Friday the 13th and certain warned-against activities do. Just as walking under a ladder is considered unlucky, crossing paths with a black cat is also thought to be a harbinger of bad luck.

However, not all cultures consider black cats to be unlucky. In Japan, for example, they are considered an omen of good fortune. In fact, there is no scientific evidence that says black cats cannot make loving and deserving pets.
