Chartreux: This is a friendly, intelligent, self-confident and affectionate breed, but not intrusively so. Chartreux cats tend to be quiet-voiced and typically do not annoy their owners with constant meowing or crying. They are quite observant and have been known to operate radio buttons and open screen door latches with their faces and paws. Chartreuxs are playful well into their adult years. They are gentle and good with children and other animals.
