Yin and Yang: black and white seals that look so perfect that they seem to be one

Some people believe that if a black cat crosses their path, it's unlucky. Whereas the white cat is lucky. Others say that everything is quite the opposite. In any case, black and white cats are presented as something opposite to each other, not only in color, but also according to the prejudices that feed human fears. 

We don't believe in all this. Therefore, we present a selection of wonderful black and white cats who, it seems, cannot live without each other. Like yin and yang, together they look so perfect, as if they are parts of one whole.
