Black cats have been overlooked, hated, feared and even loathed by many. They are symbols of a bad omen or bad luck in many western cultures. For this reason, Black cats are offten surrenderd or placed in shelters, where they are the least adopted type of cat. More black cats die in shelters every year than any other type of cat. 

But Black cats are not bad luck. In many cultures, black cats are also symbols of good luck. The times of the middle ages are over, so people should stop obsessing over this conspiracy theory that harms thousands of cats each year.
