Although most people know that the vast majority of calico cats are female, they don't always know that calico refers to a color pattern, not a breed of cat.

What Is a Calico Cat? Calico cats are popular choices for cat lovers because of their gorgeous coats. But, unlike a Siamese or Persian cat, calico is not a feline breed. A calico can be a Persian, Maine coon, Manx, or several other breeds. For a cat to be labeled calico, their coat must contain three colors—black, white, and orange. These three colors appear on the coat in patches, often with white in the highest concentration. Calico cats are named for their coat color that resembles calico cloth, which was once imported from England to India.

Calico cats are often mistaken for tortoiseshell cats, and the terms can be used interchangeably in some regions. Tortoiseshells differ from calicos in that the colors are mixed or blended, with no white, while calicos have distinct patches with a large amount of white. Calicos can also have dilute coats, with fawn, cream, chocolate, and gray patches, rather than the traditional bright white, orange, and black.

What Breeds of Cats Can Be Calico? Since we've established that calico is a color pattern, not a breed, does that mean that any cat can be calico? Many breeds can produce calico cats, but not all. Why Are So Many Calico Cats Female? It's a fact that 99.9 percent of all calico cats are female because of the unique chromosomal makeup that determines the color variations in their coats.

The chromosomes (X and Y) determine whether a cat will be male or female. Each cat has a pair of sex chromosomes with the possible combinations of XX (female) and XY (male). The X chromosome also carries the coding gene for the black and orange colors in a calico's coat. Female calico cats have two X chromosomes, and therefore have two chromosomes with color code. Only if the cat gets one orange-coded X and one black-coded X, she will be calico, expressing both black and orange coloration.

For example, a cat receives an X chromosome from her mother that codes for black fur and an X chromosome from her father that codes for orange fur. While it only takes one X chromosome to make the fur a certain color, females are special with two X chromosomes. During development, one X chromosome will override the other, allowing either black or orange to be the dominant color.

Unfortunately, since male calico cats are born because of a genetic anomaly, they are often much less healthy than their female counterparts. Male calicos often have reduced bone mineral content, increasing the risk for broken bones; cognitive and mental developmental issues, which can lead to behavioral problems; and increased body fat, which can cause joint pain, heart disease, and diabetes. It's possible for male calicos to live long and healthy lives, but these special kitties require dedicated caretakers.

This particular color development occurs in each individual cell, shutting down one X chromosome while allowing the other to be active. With varying dominant X chromosomes, a cat's colors will also vary, which gives calico cats the orange and black colors. But, where do the white patches come from?

To make things even more complicated, calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. They'll only express either black or orange, but not both.

How Do Male Calico Cats Occur? There is one exception to the females-only calico rule: A genetic anomaly called Klinefelter's Syndrome. Klinefelter's Syndrome occurs when a male inherits an extra X chromosome from either his father or mother, making his genetic makeup XXY. About one in every 3,000 calico cats is born a male, meaning there's less than a 0.1 percent chance of a calico cat being born a male. These unicorn cats are almost always sterile, so they cannot be used to breed more calico patterns.

If you're looking to welcome a calico kitty into your life, chances are she'll be a female. But, you may get lucky and find a unicorn cat—a male calico. Whatever your feline friend's color, you're sure to enjoy your new cat's company.
