The Chartreux cat breed is large and muscular with short fine boned limbs, big paws, and very fast reflexes. They are known for their gray, water resistant, short hair double coats and gold or copper colored eyes. Chartreux cats are also known for their "smile". Due to the structure of their heads and their long, tapered muzzle, they often appear to be smiling. Chartreux cats are exceptional hunters and were highly prized by farmers.
