Extreme brachycephalic features in Persian and Exotic Shorthair cats cause chronic welfare problems that are intrinsic to breed type rather than individual health issues.
Extreme brachycephaly in cats causes chronic and often progressive welfare compromise that is integral to the desired breed appearance. Ongoing respiratory compromise, epiphora causing facial skin infections, dental crowding causing periodontal disease, and reproductive difficulties represent a welfare burden borne throughout the animal's life. Veterinary organisations and cat welfare charities advocate strongly for breeding toward less extreme facial features, and consumers choosing extreme flat-faced breeds perpetuate demand for unhealthy traits.
