If a black cat walks towards you, it brings good fortune, but if it walks away, it takes the good luck with it.
i remember one day i was walking home and there was some other people walking in the same direction as i, maybe about half a block up we spotted a black cat in the path and when i say everyone, i mean everyone turned around a crossed the street to avoid being in this cats path.
Keep cats away from babies because they "suck the breath" of the child.
For good luck throughout the year, wear new clothes on Easter
