About Black Cat Appreciation Day
In most Western cultures, black cats have typically been looked upon as a symbol of evil omens, specifically being suspected of being the familiars of witches, or actually shape-shifting witches themselves.
Most of Europe considers the black cat a symbol of bad luck, particularly if one walks across the path in front of a person, which is believed to be an omen of misfortune and death. In Germany, some believe that black cats crossing a person's path from right to left, is a bad omen, but from left to right, the cat will bring good luck.
Though the name of the man who chose August 17th is not recorded, it is said that he thought to celebrate this day for black cats as his sister died on the same day after the death of her black cat just before two months. He marked this day to honor her sister and her bond with her cat.
