Am I a superstitious person?

This is the history of one boy that his father bought a black cat, his neighbors said that it was very bad luck however, the kitten died at 9 years old, and one of his brother was no able to study for health reasons, and the rest of his brothers are truly successful.

Well I really think that this is true because the color of any animal doesn´t have to do with the luck or with the future.

Because people have the necessity of believe in something, or simply because they know any experience about that superstitious.
