The Chartreux is a French breed whose blue-gray ancestors turn up in writing as far back as the sixteenth century. It nearly disappeared after World War I and was rebuilt in the 1920s from natural colonies of blue cats. It remains uncommon in the US. Every Chartreux is blue, with a dense, woolly, water-resistant coat, gold to copper eyes and a sturdy, muscular body on fairly short legs. Adults usually weigh 7 to 14 pounds.
Many Chartreux are calm, gentle and quietly devoted, though each cat differs. Expect slow maturity, a cat that gains weight easily without play and measured meals, and a thick coat that sheds in seasonal waves. Regular brushing keeps loose fur under control, which matters in a small apartment.
