Persian and Exotic Shorthair cats with extreme flat faces suffer from chronic respiratory and ocular problems that raise fundamental welfare concerns about selective breeding practices.
Brachycephalic cats live with chronic respiratory compromise that worsens with stress, heat, and exertion. Many cannot breathe comfortably while eating, drinking, or playing. The appealing 'flattened face' aesthetic that drives demand directly causes the welfare harm. Veterinary associations including the BVA and AVMA have published positions against extreme brachycephaly. Prospective cat owners who choose moderate-faced individuals make a welfare-positive decision that reduces demand for harmful breeding.
