there is a superstition in English that it is bad luck for a black cat to cross your path so most people fear the black cat. I personally like black cats and my nickname is the black cat (la gata negra). so as I am like the black cat, I don't have anyone to fear or any bad luck to receive from anyone or anything crossing MY path. so I would like the translation to be
"The black cat does not fear anyone that crosses its' path
