Answer: A calico cat isn’t a specific type of breed — in fact, they can be any domestic cat breed with a tri-color coat; typically black, orange, and white. Variations including cream, blue-black, brown, and reddish-orange can also be found in calico cat coats. The various patterns of the calico patches are almost as ubiquitous as snowflakes. You'll never see two exactly alike. Calicos are almost all female, and the rare male is always sterile. The calico is Maryland's state cat, chosen because its white, black, and orange coloring is similar to that of the Baltimore oriole.
