About the breed
The Chartreux, known in France simply as chartreux, is one of the oldest natural cat breeds, originating in France. It is recognized by its dense, blue-grey woolly coat, copper-to-gold eyes, and a broad face that gives the impression of a permanent faint smile. It is a calm, quiet, and devoted cat that spent centuries as part of the French countryside, came close to extinction twice during the 20th century, and was saved by a handful of dedicated breeders. Today the Chartreux is recognized by all major cat associations, including the CFA and the French registry LOOF.
Origins in France
Traces of blue-grey cats in France go back to the 16th century - French poet Joachim du Bellay described his grey cat Belaud in 1558, suggesting solid grey cats were already common in France at the time. In the 18th century, naturalists Linnaeus and Buffon described the breed as the French blue cat and even gave it the Latin name Felis catus coeruleus. The first known use of the name 'chartreux' for blue cats appears in Savary's Universal Dictionary of Commerce from 1723, which states the cat was named after the Carthusian monks who supposedly owned the first specimens of the breed.
The monk legend and the real story behind the name
The story that the breed was bred by monks of the Grande Chartreuse monastery in the French Alps is popular among cat lovers but poorly documented. In 1972, the monastery's prior, at researchers' request, searched the archives and confirmed there was no record of any deliberate breeding of this or any other cat breed there. Historian Jean Simonnet proposed a more likely explanation: the name probably derives from 'pile des Chartreux,' a prized 18th-century Spanish wool known for its dense, curly texture resembling the cat's coat. Naming an animal after a well-known material was common practice in the livestock breeding of the era, which is why the CFA today treats the monk legend as historically unconfirmed.
A breed that nearly disappeared
The Chartreux came close to extinction twice. World War I sharply reduced the population, and after World War II only a small number of animals survived from France's natural colonies. A colony of cats at a hospital on the island of Belle-Île off the Brittany coast played a key role in reviving the breed, where the Léger sisters began deliberate breeding. After the war, because of the small remaining gene pool, breeders occasionally crossed surviving cats with British Shorthairs and Persians. In 1970 the international federation FIFe briefly merged the Chartreux with the British Blue under one standard, but French breeders won separate recognition for the Chartreux as its own breed in 1977.
Appearance: blue-grey coat and copper eyes
The Chartreux has a medium-length, slightly woolly coat with a dense undercoat and a water-resistant topcoat that, in older cats, tends to 'break' at the neck and flanks much like sheep's wool. Coat colour ranges from ash grey to slate blue, without patterns or markings. The eyes are round and expressive, ranging from copper to gold, with a clear, brilliant orange being most prized. The body is stocky and muscular, with broad shoulders, a deep chest, and comparatively short legs, while the round head with full cheeks and a narrow muzzle gives the cat its trademark faint 'smile.'
A quiet, devoted temperament
Chartreux cats are known for being unusually quiet - many barely meow at all, communicating instead with soft, high-pitched chirping sounds. Rather than vocalizing, they rely on expressive eyes and body language, which has earned them a reputation as 'silent hunters.' They are calm, even-tempered, and deeply devoted to their family, though initially reserved with strangers. They are generally patient and adaptable with children and other pets, though they need more time to adjust to dogs. They stay playful throughout their lives and enjoy following their people around the house without being demanding.
Coat care
Despite its density, the Chartreux coat is not demanding to maintain - weekly brushing is enough to remove dead hair and keep the coat glossy. During spring and autumn coat changes, when the cat sheds its undercoat, brushing several times a week is recommended. Because it is a stocky, muscular cat prone to weight gain, it is important to monitor food intake and encourage regular activity. Dental care also matters, as the breed has been noted to be prone to tartar build-up and gum inflammation.
Health and life expectancy
The Chartreux is generally a healthy, robust breed with a life expectancy of 12 to 15 years. Part of the population has been reported to carry a hereditary predisposition to patellar luxation (a dislocating kneecap), which is why responsible breeders recommend a knee check as early as the time of spay or neuter. Because the cat matures slowly - not reaching its full physique until three to five years of age - and tends toward weight gain, a balanced diet and regular veterinary check-ups are important throughout its life.
Temperament
A calm, even-tempered, quiet cat that is deeply attached to its family but initially reserved with strangers. It rarely meows, preferring soft chirps or body language instead. It stays playful throughout its life and enjoys following its people around the house.
Suitable for
Well suited to families with children, households with other pets, apartment dwellers, and first-time owners looking for a calm, unobtrusive cat.
Living environment
The Chartreux adapts very well to apartment living, since it is calm, quiet, and does not need much space as long as it has room to climb and play. It also thrives in a house with a garden, where it can explore under supervision.
Grooming
Weekly brushing is enough for the coat, more often during seasonal shedding. Since the breed tends toward weight gain, controlled feeding and regular activity are needed. Regular dental care is also recommended, as the breed has a noted tendency toward tartar buildup.
