Black Cat

A black cat is a domestic cat with black fur. It is not a particular breed of cat and may be mixed or a specific breed. The Bombay, known for its sleek black fur, is an example of a black cat. The all-black pigmentation is slightly more prevalent in male cats than female cats. Their high melanin pigment content causes black cats to have yellow (golden) eyes (irises). Black cats can also "rust" in sunlight, the coat turning a lighter brownish shade.  Source
