    Fun fact: while almost all calico cats (tricolor coat) are female, around 1 in 3,000 are males with an extra X chromosome, a condition known as Klinefelter syndrome. As a result, they are almost always sterile. About 1 in 10,000 male calicos are fertile.

    Also, around 80% of orange cats are male.

        Orange and calico are just some of the possible colorings of a cat’s fur and don’t determine its breed (although some breeds are known for having distinctive colors and patterns).
