Marie The Calico Visited Us In Natomas

See lots of dogs and an occasional cat at

We were at our Sacramento clinic in the Natomas area when we found this rare opportunity to photograph a cat with no risk of escape. Marie is a Calico which includes three colors. The 3 colors that make the typical calico coloring are black and orange-brown on white. We often refer to ‘Calico’ as a breed but it is actually a color. The body type is consistent and the hair coat is usually short. The genetics of calico color are sex-linked (ya gotta be a double-X in order for the complicated genetics of the various colors to interact) so calicos are females. Because males have only one X chromosome (and one Y) the interaction between colors does not happen and often the brothers of calico females are just orange or orange tabby but that is not a sex-linked color so there are also female orange tabbies. Is that simple? – Geoffrey Antipa
