Info on the breed:

Black smokes are pure black.  You can tell that your cat is a black smoke if you peel back the hair and the skin is white.  The roots of the hairs are gray and then get blacker and blacker as it the hair extends upwards.  The end of the hair should be black.  Black Smokes have black pads, and green or yellow eyes.   Black Smokes are short haired cats and require little grooming.
