"Whenever the cat of the house is black, the lasses of lovers will have no lack"

I just don't understand why (Supersticious) People are saying or thinking that Black cats bring accidents.Let me tell you guys something: That's so not true, a cat is a cat and it will always stay like that.If it is green or yellow or blue or red, it will always stay a cat.A black cat has a magical radiation (black is the color of magic).But why so overweening? that poor little thing just needs some love.Believing in superstition bring bad luck.
