Research overview: brachycephaly and welfare in flat-faced cat breeds

Selective breeding for a flat, shortened face in Persians and related breeds produces brachycephaly, and this overview surveys its welfare consequences. It examines how extreme facial conformation is associated with breathing difficulties, dental crowding, eye problems including tear overflow and ulceration, birthing complications and skin-fold issues, paralleling concerns documented in brachycephalic dogs. The survey discusses studies quantifying these health problems, the trade-off between aesthetic breed standards and animal welfare, and calls to moderate extreme conformation. It connects feline brachycephaly to broader debates about breeding for appearance at the expense of health, presenting the flat-faced cat as a case where human preference for a particular look has created predictable, breed-linked welfare burdens, and noting growing attention to reforming standards to prioritize the wellbeing of these popular breeds.
