The Chartreux is a medium-sized French cat with a plush, blue-gray coat that is dense, woolly and water-resistant. Its eyes run from gold to copper, and its body is sturdy and muscular on fairly fine-boned legs. Most adults weigh 7 to 14 pounds, with males noticeably bigger, and many take three to five years to fully mature.
Daily care is simple but steady. Brush weekly, and more often during the heavy sheds in spring and fall. Feed measured meals and schedule play, because this cat puts on weight easily. A Chartreux is happiest indoors with a routine and a person nearby. Because blue shorthairs can look alike, a cat's personality and comfort level tell you more about fit than its label does.
