The Chartreux is a French breed with a plush, water-resistant blue coat, gold to copper eyes and a sturdy, muscular build on fairly short legs. It nearly disappeared after World War I and was rebuilt in the 1920s from natural colonies of blue cats, which is part of why it's still uncommon in the US.
In a Minneapolis home, that dense coat matters most during seasonal sheds, when regular brushing keeps fur off the furniture. Chartreux are often calm, quiet and devoted, though each cat has its own personality. They mature slowly, over several years, and gain weight easily without play and measured meals, so a steady routine helps. Many are comfortable alone during a workday but still like company in the evening.
