A popular belief in the western hemisphere holds that black cats are unlucky. This superstition is not universally held, however. In Asia and the U.K., a black cat is generally considered lucky. The exception, is that in most of the U.K., it is unlucky to cross paths with a black cat. As there are exceptions to every rule, including exceptions to exceptions. In Yorkshire, England, it may be lucky to own a black cat, but it is unlucky have one cross your path. (I wonder how one handles the latter if she lives with black cats.) Superstitions, like genetics, can be a very confusing subject, indeed.
