This anomaly can also cause Klinefelter’s Syndrome, a health issue that may result in some health problems for calico males. Only one in 10,000 male calicos are born fertile because of this rare XXY configuration.
Meet Sherman, one in 3,000. A stray male calico who showed up at the Humane Society Silicon Valley! While these cats present as male, they are calico because of the double X chromosome. Good luck finding one! There's less than a 0.1% chance of a calico cat being born male. Approximately one in 3,000 calicos are male.įor a male cat to have calico colors, it must have an extra X chromosome, making it XXY.

Calico actually refers to a cat’s coat color and fur pattern. To get down to brass tacks, “calico” is not a breed of cat. (Okay, even I cringed at that pun.)
