Dilute calico describes a coat, not a breed: a white cat with patches of soft blue-gray and cream, the pastel version of the classic black, orange and white calico. The softer shades come from two copies of a recessive dilution gene, and the amount of white ranges from a little on the paws and chest to most of the body. Because the orange color gene sits on the X chromosome, nearly all dilute calicos are female.
Most dilute calicos you'll meet are domestic shorthairs or longhairs, though the pattern turns up in many breeds. Color says little about personality, so shy, bold, cuddly and independent cats all wear it. A cat's age and background say far more about how she will settle in. Longhaired cats need more brushing, especially in humid weather.
