Only one out of every 3,000 calico cats is male, according to a study by the College of Veterinary Medicine at the University of Missouri. Why is a male calico cat rare?

Just like humans, cats have two sex chromosomes that determine gender. Female cats have only X chromosomes while male cats have both X and Y chromosomes. A calico or tortoiseshell must have two X chromosomes which means the kitty is going to be female 99.99% of time.

The calico pattern exists in male cats is because the cat has an extra X-chromosome: two X, one Y (male). In humans, this condition is known as Klinefelter Syndrome.

Frank is not the only male calico that has been reported.
