cats with a spotted or parti-colored coat that is predominantly white, with patches of two other colors (often, the two other colors are orange tabby and black).Because genetic determination of some coat colors in cats is linked to the X chromosome, calicoes are nearly always female. Because of the genetics involved, calico males are rare, and generally have impaired vitality and are almost always sterile.
Cats of this coloration are believed to bring good luck in the folklore of many cultures. In the United States, these are sometimes referred to as money cats. The Japanese Maneki Neko figurine is almost always a calico cat. A cat of the calico coloration is also the state cat of Maryland in the United States.
