Black Cats found their infamous symbolism in the Middle Ages for being the familiars or companions of witches. Often times these so called witches were simply women who had knowledge of herbs and remedies or who attracted the wrath of a male dominated church. Their black cats were seen as demons in disguise and messengers from Satan. It didn't help the Crusades happened during the middle ages and as the European knights and soldiers were fighting the "infidels" in the middle east, they were venturing into Egypt, a country that revered cats as gods.
As innocent women were tortured and killed out of religious fear or for political reasons for a few hundred years, the black cat became an enduring symbol for feminism, freedom from male domination and Pagan spiritual beliefs. The black cat, shown with an arched back and extended claws, is also a little known symbolism of anarchist values. One of the back stories behind it is that a group of anarchist workers were striking against their employers and losing badly when a stray black cat wandered into their camp. The workers fed and cared for the stray and as the cat gained strength, their strike began to gain ground. They eventually won their strike and adopted the black cat as their mascot.
