A superstition is a widely held but unjustified belief in supernatural causation leading to certain consequences of an action or event, or a practice based on such a belief.Over the years many people have been very superstitious about the black cat. The reason for that is they say when a black cat crosses a road and you go through wherever it crosses it is believed to be an omen of bad luck or death. The fears about black cats are throughout Europe over time and a lot of killings of black cats took place. Although certain areas of Europe, places in the UK, had some positive black cat superstitions, the black cat was often mistreated and did wrong. Fortunately for the black cat, there have also been good black cat superstitions where people admire or even worship the feline.
