in CFA's, simply with a more general name, though the organizations do not mix breed registries. The International Cat Association (TICA) groups the breed into three coat-pattern divisions for judging at cat shows: traditional (with stable, rich colors), sepia ("paler and warmer than the traditional equivalents", and darkening a bit with age), and mink (much lighter than sepia, and developing noticeably with age on the face and extremities). If classified as the Himalayan sub-breed, full point coloration is required, the fourth TICA color division, with a "pale and creamy colored" body even lighter than mink, with intense coloration on the face an extremities. The four TICA categories are essentially a graduated scale of color distribution from evenly colored to mostly colored only at the points. Within each, the coloration may be further classified as solid, tortoiseshell (or "tortie"), tabby, silver or smoke, solid-and-white, tortoiseshell-and-white, tabby-and-white, or silver/smoke-and-white, with various specific colors and modifiers (e.g. chocolate tortoiseshell point, or fawn shaded mink marbled tabby-torbie). TICA-recognized tabby patterns include classic, mackerel, marbled, spotted, and ticked (in two genetic forms), while other patterns include shaded, chinchilla, and two tabbie-tortie variations, golden, and grizzled. Basic colors include white, black, brown, ruddy, bronze, "blue" (grey), chocolate, cinnamon, lilac, fawn, red, cream, with a silver or shaded variant of most. Not counting bi-color (piebald) or parti-color coats, nor combinations that are genetically impossible, there are nearly 1,000 named coat pattern variations in the TICA system for which the Persian/Himalayan qualifies. The Exotic Shorthair sub-breed qualifies for every cat coat variation that TICA recognizes. Eye colors range widely, and may include blue, copper, odd-eyed blue and copper, green, blue-green, and hazel. Various TICA and CFA coat categorizations come with specific eye-color requirements. Health Pet insurance data from Sweden puts the median lifespan of cats from the Persian group (Persians, Chinchilla, Himalayan and Exotic) at just above 12.5 years, while most cats live until they are about 15 years old. 76% of this group lived to 10 years or more and 52% lived to 12.5 years or more. Veterinary clinic data from England shows an average lifespan of 12–17 years, with a median of 14.1. The modern brachycephalic Persian has a large rounded skull and shortened face and nose. This facial conformation makes the breed prone to breathing difficulties, skin and eye problems, and birthing difficulties. Anatomical abnormalities associated with brachycephalic breeds can cause shortness of breath. Malformed
