Calico is a color, not a breed of cat, but it happens to be one of the most popular colors for cat coats, with more than 140,000 people searching for the term on Petfinder.com. People love the mix of white, black and orange that makes up this unique coat.
They can be long- or shorthaired, but they are almost always female, as the color is gender-linked. Male calicos are rare (one in 3,000, according to a study by the College of Veterinary Medicine, University of Missouri) and sterile.
