Calico cat facts for kids
A calico cat is a domestic cat with a beautiful three-color coat. These cats typically have patches of black, orange (or red), and white fur. In some parts of the world, like outside of North America, these cats are called tricolor or tortoiseshell and white.
It's important not to confuse a calico cat with a tortoiseshell. Tortoiseshell cats usually have two colors, like black and orange, but they don't have the large white patches that calico cats do. Calico cats often have 25% to 75% white fur, along with their bright orange and black spots. Sometimes, their colors might be "diluted," meaning they look softer, like blue-gray instead of black, or cream instead of orange. These are sometimes called calimanco cats. If a calico cat also has tabby stripes within its colored patches, it might be called a caliby or tabico.
The name "calico" comes from a type of colorful printed fabric. When we talk about calico cats, we are only describing their fur pattern, not a specific breed of cat. Many different cat breeds can have calico coloring. Almost all calico cats are female. It's very rare to find a male calico cat, and this usually happens because of a special genetic condition.

The Story of Calico Cats
Where the Name "Calico" Came From
The word "calico" originally referred to a type of fabric that came from the city of Calicut in India. This fabric was known for its colorful, printed designs. When these fabrics were brought to the United States, people started using the word "calico" to describe the bright, mottled patterns. This is how the term came to be used for cats with their unique three-color coats, because their fur looked like the patterned fabric.
A Colorful History

The special three-color pattern of calico cats isn't tied to one specific cat breed or a single historical event. However, scientists have studied how these colorful cats spread around the world. Research suggests that the gene responsible for the orange color in calico cats likely traveled along ancient trade routes. These cats were often found in port cities around the Mediterranean Sea, like those in Greece, France, Spain, and Italy, with their origins possibly tracing back to Egypt.
Maryland's State Cat
Since October 1, 2001, the calico cat has been the official state cat of Maryland, USA. Calico cats were chosen for this honor because their white, black, and orange colors match the colors of Maryland's state bird, the Baltimore oriole, and the state insect, the Baltimore checkerspot butterfly. It's a fun way to celebrate these colorful felines!
The Science Behind Calico Colors
Calico cats are very similar to tortoiseshell cats in their genetics, except that calicos have white patches. Interestingly, the more white a calico cat has, the larger and fewer its patches of orange and black tend to be. This is different from a tortoiseshell cat, which usually has many small patches of color.
Scientists began to seriously study calico cats in the 1940s. Researchers like Murray Barr noticed tiny, dark, drumstick-shaped spots inside the cells of female cats, but not in male cats. These spots became known as Barr bodies. Later, in 1959, a scientist named Susumu Ohno discovered that these Barr bodies were actually X chromosomes. Then, in 1961, Mary Lyon explained a key idea called X-inactivation. She proposed that in female mammals, one of the two X chromosomes in each cell "shuts off" or becomes inactive.
This X-inactivation is why calico cats have their unique patterns! Female cats have two X chromosomes. The genes for orange or black fur are found on these X chromosomes. Because one X chromosome randomly turns off in different cells as the cat develops, some patches of fur will show the orange color, and other patches will show the black color. The white patches are controlled by a different gene.
Why Most Calico Cats Are Female
Calico cats are almost always female because the gene that controls orange or black fur color is located on the X chromosome. Female cats, like human females, normally have two X chromosomes (XX). This means they can carry both the gene for orange fur and the gene for non-orange (black) fur.
Male cats, however, normally have one X and one Y chromosome (XY). Since the Y chromosome doesn't carry the fur color gene, a normal male cat can only have one color gene from its single X chromosome. So, a male cat would typically be either orange or black, but not both.
Very rarely, a male cat can be a calico. This happens in a special genetic condition called XXY, also known as Klinefelter syndrome. In this case, the male cat has an extra X chromosome. This extra X chromosome allows the cat to have both the orange and non-orange color genes, just like a female cat. However, male cats with Klinefelter syndrome often face health challenges and usually cannot have kittens.
The study of calico cats has helped scientists learn a lot about the differences between male and female mammals at a cellular level.
Calico Cats and Good Luck
In many cultures around the world, calico cats are believed to bring good luck. For example, in Germany, they are called "Glückskatze," which means "lucky cat." In the United States, some people even call them money cats.
In Japan, the famous Maneki-neko figures, which are waving cat statues, often show calico cats. These figures are thought to bring good luck and fortune. Japanese sailors used to keep calico cats on their ships, believing the cats would protect them from bad luck and storms at sea.
Calico Cats in Stories
In the late 1800s, a well-known children's poet named Eugene Field wrote a poem called "The Duel." This poem, also known as "The Gingham Dog and the Calico Cat," tells a fun story about these two characters.
