In the cat world fur color is a gender-specific trait related to chromosomes. Calico coats are associated with female cats and for good reason only one out of every 3000 Calicos are male according to a genetic study by a researcher team at the University of Missouris College of Veterinary Medicine.
Calico cats are tri-color and have mostly white with patches of black and orangered.
Do male calico cats die when they are born. Male calico cats do not die when they are born but they often do not live as long as the females and live with several health concerns.

The cats with the XXY chromosome pattern are infertile and these cats do have a lot of health problems. That doesnt mean they always die right after birth. In both cases the result is a male cat who can inherit the trait for a true calico coat.
Among humans this genetic arrangement is called Klinefelter syndrome. A male calico usually cannot sire offspring because the genetics described above almost always guarantees that he will be sterile. This gene cannot be passed on to a male offspring hence why its very rare that calico cats are male.
