3 Surprising Scientific Facts About Orange Cats for Ginger Cat Appreciation Day

September 1 is Ginger Cat Appreciation Day! Here are three scientific facts to further appreciate about ginger cats. Science has uncovered surprising answers about their orange coats and whether their reputation for being especially friendly holds up.

Most Ginger Cats Are Male

If you have a ginger cat at home, there’s a good chance he’s male.

The genetic trait for orange fur is carried on the X chromosome. A male cat has only one X chromosome. Inheriting the orange trait from his mother is enough to give him orange fur. A female needs to inherit the trait from both parents to have a fully orange coat.

In 2025, researchers at Stanford University traced the color to a small piece of missing DNA near a gene called ARHGAP36. The deletion changes the gene’s activity in pigment cells and gives cats their orange coloring.

All Ginger Cats Display Tabby Patterns

Tabby patterns appear across various cat breeds, including Maine Coons, American Shorthairs, and Persians. Every orange cat displays some form of the pattern. Ginger cats may have narrow stripes, broad swirls, spots, or a ticked coat with less obvious markings.

A genetic variant called nonagouti can hide the tabby pattern in cats with non-orange fur and make their coats appear solid. Scientists found that orange cats show tabby markings even with a nonagouti variant.

People Perceive Ginger Cats as Friendlier

Researcher Mikel Delgado found that people were more likely to associate orange cats with friendliness.

Delgado and his colleagues examined how people perceived cats of different coat colors. The researchers surveyed people about the personality traits they associated with each coat color rather than observing the cats’ behavior. 

The results showed that people viewed orange cats as friendlier, but the study did not determine whether orange cats actually behave that way.
