The Chartreux is a rare breed of cat from France, and is recognised by a number of registries around the world. The Chartreux is large and muscular (called cobby) with relatively short, fine-boned limbs, and very fast reflexes. They are known for their blue (silver-grey) water-resistant short hair double coats which are often slightly thick in texture (often showing "breaks" like a sheepskin) and orange or copper-coloured eyes. Chartreux cats are also known for their "smile"; due to the structure of their heads and their tapered muzzles, they often appear to be smiling. Chartreux are exceptional hunters and are highly prized by farmers.
