PUT THE BLAME ON THE BLACK CAT

This black cat likes to loiter in my porch.  Some people say that black cats are unlucky but then there are two black cats that hang out in my house and the neighbours' houses.
Well, first of all. I don't think that they bring bad luck as the people in my neighbourhood are okay.  So to those out there who blame the black cat for their misfortune, it is really unjust.
