Dilute calico is a coat pattern, not a breed: white with soft patches of blue-gray and cream, the pastel version of the classic black, orange and white calico. Two copies of a recessive dilution gene soften the colors, and the amount of white ranges from a little on the paws to most of the body. Nearly all calicos are female, since the orange color gene sits on the X chromosome.
Most dilute calicos you'll meet are domestic shorthairs or longhairs, though the pattern also turns up in Persians, Maine Coons and other breeds. Color says little about personality, so a dilute calico may be cuddly, reserved or bold. Coat length sets the grooming routine, and the cat's age and background shape how quickly it settles in far more than color does.
