A black cat is a felid whose fur is uniformly black.
It is not a particular breed of cat and may be mixed or of a specific breed. The all-black pigmentation is equally prevalent in both male and female cats. The black color is of obvious benefit to a cat hunting at night. In Western history, black cats have often been looked upon as a symbol of evil omens: in other cultures they are considered to be good omens.
