It means that you and a black cat are traveling on perpendicular paths.
What Does Black Cat Crossing Your Path Mean?
A black cat crossing your path is a superstition that bad luck will happen to you, like walking under a ladder or opening an umbrella inside a house. If you are driving when a black cat crosses your path then supposedly marking an X on your windshield will block the bad luck. If you are walking, then you are supposed to turn around in circles 3 times, this way you have changed the path you were on and the bad luck will not get to you. BUT!!! Owning a black cat and having one live in your house is supposed to be GOOD luck! It depends if you are superstitious or not. ;)
