The Chartreux is an old French breed whose blue-gray ancestors turn up in sixteenth-century writing. It nearly disappeared after World War I and was rebuilt in the 1920s from natural colonies of blue cats. Every Chartreux is blue, with a dense, woolly, water-resistant coat, gold to copper eyes and a sturdy body on fairly short legs. The tapered muzzle gives it a faint smile.
Many are gentle, quietly devoted and inclined to follow a favorite person from room to room. Most speak in soft chirps and play in short bursts, especially with hunting toys. They mature slowly, shed more heavily in spring and fall, and gain weight easily without play and measured meals. In Houston, that heavy undercoat and the heat are worth planning for, but each cat's own personality matters more than the breed description.
