No registry sets a formal weight. Sources give: TICA 12-16 lb (about 5.4-7.3 kg) for mature cats; GCCF 11-18 lb (about 5-8.2 kg); Purina UK 2.7-9 kg; CFA says males reach about 14 lb (6.4 kg) and are clearly larger than females. The male range here uses TICA's lower bound and Purina's upper bound; the female range uses Purina's lower bound and TICA's upper bound. Males also mature more slowly, taking 3-5 years to fill out.

Coat and looks how to spot one

medium-short, dense, woolly double coat

The coat has a slightly harsh, water-shedding outer layer over a thick, plush undercoat, so it feels woolly and tends to part or 'break' like sheepskin when you run a hand over it. It grows noticeably fuller in winter. Underneath is a sturdy, broad-shouldered, muscular body standing on comparatively slim, fine-boned legs. The head is broad and rounded with full cheeks (heavier jowls in males), narrowing to a small muzzle that gives the face a gentle built-in smile, lit by round copper to gold eyes.13426

Coloursblue-grey only, any shade from pale ash to deep slate, often with a silvery sheen at the tipseyes: yellow, gold, copper or deep orange (deep orange preferred by CFA)134

Personality what they are like

A composed, easy-going cat that likes being near its people without demanding constant attention. It often picks one favourite person while staying friendly with the whole household. Chartreux are thoughtful observers, rarely noisy (some barely meow at all, preferring tiny chirps and body language), and generally get along with children, other pets and older owners. They are gentle and non-aggressive, travel well, and keep a playful streak into adulthood, including dog-like games such as fetching.123465

Daily activity how busy a day looks

Moderate. They play in short, energetic bursts followed by long naps, love hunting-style games with wand toys, and enjoy climbing, though they tend to stay grounded rather than leaping about. Indoor cats benefit from daily interactive play and puzzle-type enrichment, which also helps keep a heavy-set adult in trim shape.6345

Grooming and care the hands-on bits

Comb rather than brush: a wide-toothed metal comb works through the woolly undercoat without flattening it. Weekly combing is usually enough, stepping up to several times a week (or daily) during the heavy spring and autumn moults. Baths are rarely needed. Add routine nail trims, ear checks and tooth brushing.15634

Home where they are happiest

Adapts well to flats and houses and copes with being home alone for part of the day. GCCF advises keeping them indoors or giving outdoor access only through a secure enclosure or cat-proof fencing. Provide sturdy scratching posts and floor-level to mid-height climbing spots.463

Food basics what goes in the bowl

A complete, good-quality cat food with fresh water always available. Portions need watching because this solidly built breed becomes less active with age and can put on weight easily. Some individuals do best with consistent food and gradual changes, so ask your vet when choosing or switching diets.6531

Company who they like around

Affectionate and loyal but not clingy. Happy with company of calm children, other cats and cat-friendly dogs, and bonds closely with one person in particular. Content to spend some hours alone as long as it gets attention and play when people are home.2634

The story where it all began

Blue-grey cats have been part of French life for centuries. The poet Joachim du Bellay wrote about a grey cat in 1558, the name 'Chartreux' shows up in writing by the 1600s, and in the 18th century the naturalist Buffon described the 'cat of Chartreux' as a distinct type. Painter Jean-Baptiste Perronneau included one as a pet in a 1747 portrait, unusual for the time. Where the name comes from is uncertain. A well-known tale links the cats to Carthusian monks, and TICA mentions a wool cloth, 'pile de Chartreux', that may share or have inspired the name. The cats were valued as working ratters on farms and in towns. Organised breeding began in the 1920s, with the Léger sisters among the first to build lines from the free-living blue cats, including those around Belle-Île-en-Mer. The two World Wars reduced the population dramatically, and after 1945 breeders rebuilt it, bringing in some blue British Shorthairs and Persians while keeping the Chartreux type. Helen and John Gamon of La Jolla, California brought the breed to North America in 1970-71, CFA granted championship in 1987, and the UK got its first Chartreux in 2014, with GCCF recognition following in 2015. Remarkably, the modern breed description still closely matches the 18th-century one.231465

Fun facts for the dinner table

  1. 1

    Breeders follow a French tradition where every kitten born in a given year gets a registered name starting with that year's letter, cycling through 20 letters of the alphabet (K, Q, W, X, Y and Z are skipped).1

  2. 2

    General Charles de Gaulle had a Chartreux named Gris-Gris that reportedly trailed him from room to room.2

  3. 3

    The writer Colette made a Chartreux the heroine of her novel 'La Chatte'.2

  4. 4

    Thanks to the shape of the head and narrow muzzle, the Chartreux always seems to be wearing a gentle smile.1

  5. 5

    Some Chartreux have been known to work out how to press radio buttons and open screen-door latches.2

  6. 6

    Their outer coat is somewhat water-repellent, a handy feature for a cat that once earned its keep catching rodents outdoors.3

  7. 7

    A blue Chartreux called 'Ste Cat' served as mascot of the Montreal International Jazz Festival.2

  8. 8

    Chartreux mature slowly and can take three to five years to reach full adult size and build.1
