Chartreux Cat Breed Information

Chartreux cat is a French feline with uncertain origins but a pleasant demeanor that has made it the unofficial cat of France and a beloved pet abroad. The breed is notable for its solid blue-gray coat with a slightly woolly texture, bright copper or orange eyes, and quiet but friendly nature.



The origin of the Chartreux is very well-established that the breed dates back to the 15th or 16th century. The breed has a religious background. The unique woolly coat of these cats points back to Syrian roots, and it was believed that Crusaders returning from Syria to France brought the ancestor of the breed along.

Once in France, the cats proved themselves to be an excellent means of controlling rodent populations. Many accounts of the Chartreux’s history point to French Carthusian monasteries keeping these cats as a defense against rats and mice.

In the 1920’s, a methodical Chartreux breeding program was started when sisters Christine and Suzanne Leger encountered a colony of blue-gray cats living on a small island off the coast of France. The cats were notable for their striking appearance and unique woolly coat and the Leger sisters began to domesticate and breed them. Thus, resulting a strong, healthy Shorthaired Blue cat with a lovely face and a powerful body. In 1931, the cats were on a display at a cat show in Paris and the modern Chartreux cat became recognizable.

The breed then imported to Britain, not only to be bred as its own breed, but also to enhance the body, coat type and coat color of the British Shorthair.

During World War II, the breed was almost lost but with the help of some dedicated breeders, it has been brought back. Selective crossbreeding with Russian Blue, British Shorthair, and Persian cats ensured that this centuries-old cat didn’t disappear.

After the WWII, the breed grew in popularity in France. While first prized for its hunting prowess, the modern Chartreux became appreciated for its beautiful woolly coat, intelligence, and calm, friendly demeanor. In 1970, John and Helen Gamon brought the first Chartreux cats to the United States. This paved the way for the breed’s full acceptance into the Cat Fancier’s Association (CFA) in 1987.
