All cats shown at exhibitions arranged after FIFEs rules are judged by the FIFE breed standard for Maine Coons described beneath.
The breed is large framed with a square outline of the head, large ears, broad chest, solid bone structure, a long, hard muscled, rectangular body and a long flowing tail. Good muscle tone and density give the cat the appearance of power and robustness.
Shape: medium in size; square outline. Profile with a gentle concave slope
Forehead: gently curved
Cheeks: cheekbones high and prominent
Face/Nose/Muzzle: face and nose of medium length with a square outline of the muzzle. The distinct transition can be felt between muzzle and cheekbones.
Chin: firm, in vertical alignment with nose and upper lip
Shape – large, wide at the base, moderately pointed. Lynx-tufts are desirable, tufts of hair in the ears extend beyond outer edges of ears.
Placement – Set high on the head with a very slight outward tilt. Ears should be placed one ear’s width apart, the width extends slightly in older cats. The lower base set just slightly further back than the upper base.
Shape – Large and widely set, slightly oval, but not almond shaped. Appear round when wide open, set slightly slanted towards the outer base of the ear.
Colour – Any colour is permitted, there is no relationship between eye- and coat colour. Clear eye colour is desirable.
males have a very strong muscled neck
Structure – the body should be long, substantial bone structure, hard muscled, powerful, broad chested large framed. All parts of the body in proportion to create a rectangular appearance.
Legs – substantial, medium length to form a rectangle with the body.
Paws – large, round and well tufted between the toes
Tail – at least as long as the body from shoulder blade to the base of the tail. Wide at the base tapering to the tip, with full, flowing hair. The hair on the tail is long and always remains flowing.
Structure – all weather coat, dense. Short on a head, shoulders and legs, becoming gradually longer down the back and sides, with long, full shaggy baggy trousers on the hind legs and belly fur. A frill is expected silky texture. The coat has a distinct body, falling smoothly. The undercoat is soft and fine, covered by the coarse smooth outer coat.
Colour – all colour varieties are permitted, including all color varieties with white; except pointed patterns and chocolate, lilac, cinnamon, and fawn. Any amount of white is allowed, i.e a white blaze, white locket, white on the belly, white on the paws etc.
The maine coon should always be in good balance, condition and proportion.
