Dilute calico describes a coat, not a breed: white with patches of blue-gray and cream, the pastel cousin of the black, orange and white calico. The softer shades come from a recessive dilution gene, and the amount of white ranges from a few spots to most of the body. Nearly all are female, since the orange color gene sits on the X chromosome.
Most are domestic shorthairs or longhairs, though the pattern turns up in Persians, Maine Coons and British Shorthairs too. Color says little about personality, so a dilute calico might be bold, shy, chatty or aloof. In a city where many people rent and spend long stretches in apartments, a cat's age, coat length and comfort with routine tell you more about fit than color does.
