Category II MCO Maine Coon Standard
    The Maine Coon is a natural breed of amiable character that traces its origin to the working cat found on the farms of Northeast America.
General Appearance The Maine Coon 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.
Size Large.
Head Shape Medium in size; square outline. Profile with a gentle concave slope.
Forehead Gently curved.
Cheeks Cheekbones high and prominent.
Face and nose of medium length with a square outline of the muzzle. Distinct transition can be felt between muzzle and cheekbones.
Chin Firm, in vertical alignment with nose and upperlip.
Ears 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 head with a very slight outward tilt. Ears should be placed one ear's width apart. The width extends slightly in older cats. Lower base set just slightly further back than upper base.
Eyes 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.
Neck   Males have a very strong muscled neck.
Body 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 shoulderblade to base of tail. Wide at the base tapering to the tip; with full, flowing hair. The hair on the tail is long and always remains flowing.
Coat Structure All weather coat. Dense. Short on 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. Texture silky. Coat has distinct body, falling smoothly. The undercoat is soft and fine, covered by the coarse smooth outercoat.
Colour All colour varieties are permitted, including all colour varieties with white; except pointed patterns and chocolate and lilac, cinnamon and fawn. Any amount of white is allowed, i.e. a white blaze, white locket, white chest, white on the belly, white on the paws, etc.
