The Chartreux is an old French breed whose blue-gray ancestors turn up in writing from the sixteenth century. 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, muscular body on fairly short legs.
Many are calm, gentle and quietly devoted, often following a favorite person from room to room and chirping softly instead of meowing. That steadiness works well in a shared building, though the thick coat sheds more in spring and fall. Chartreux play in short bursts and gain weight easily, so measured meals and daily play with a wand toy matter. Like any cat, each one has its own personality.
