Blue-gray cats have lived in France for centuries, appearing in sixteenth-century writing, and the Chartreux is the breed that grew from them. After nearly disappearing following World War I, it was rebuilt in the 1920s from natural colonies of blue cats, and it remains uncommon. Every Chartreux is blue, with a dense, woolly, water-resistant coat, gold to copper eyes, a sturdy muscular body on fairly short legs and a tapered muzzle that seems to smile.
Many Chartreux are calm, gentle and quietly devoted, often following one favorite person from room to room. They tend to communicate with soft chirps rather than meows, and some barely make a sound. Most play in short bursts and enjoy hunting toys. Adopters should expect slow maturity, seasonal shedding of the thick coat, and a cat that gains weight easily without play and measured meals.
