Tuxedo Cats: Pattern, Genetics, and Breed Diversity
Tuxedo cats are a striking coat pattern, not a breed. The pattern features a dark body with white patches on the chest, stomach, paws, and sometimes the chin or face. The white spots come from the white-spotting gene (S gene), which suppresses pigment during embryonic development. The amount of white varies: low-grade spotting gives the classic tuxedo look, while higher-grade spotting produces mostly white cats with dark patches, known as van or harlequin.
The pattern is not sex-linked, so males and females appear in roughly equal numbers. It shows up in many breeds, including American Shorthair, British Shorthair, Maine Coon, Persian, Cornish Rex, Norwegian Forest Cat, Scottish Fold, and mixed-breed cats. The white-spotting gene is widespread across domestic cat populations, with early hotspots in Western Europe and Mediterranean port cities.
Each tuxedo cat is unique. Markings can be symmetrical, splotchy, uneven, or include a white “mustache.” The placement of white patches is partly random, so even kittens from the same litter can look very different.

- White-spotting levels determine whether a cat is a classic tuxedo, van, or harlequin.
- The pattern appears in many breeds and in mixed-breed cats.
- Male and female tuxedo cats occur in roughly equal numbers.
