If a black cat crosses your path, bad luck will come to you, and it can also be an omen of death. In another version, it is believed that if a black cat walks toward you, it will bring you good luck and if it walks away from you, it takes good luck away.
In ancient Egypt, all cats, including black ones, were highly regarded and well protected from death and injury. It is customary in England and Ireland that black cats bring good luck.
During the Middle Ages, black cats were seen as evil demons and companions to witches and that they should be destroyed. Because they were seen as demons, it was believed that a black cat crossing your path would block your connection to God and the entrance to heaven. The paranoia surrounding this superstition caused the destruction of a lot of black cats, as well as the killing or severe punishment of anyone who took care of them.
