Mice do not come in breeds (different shapes and sizes) like in other species, but in Varieties (different coat types). At present, mice are shown in seven Varieties, according to their coat type, namely:
STANDARD – Short, sleek coat.
SATIN – Short, sleek coat, with a lustrous sheen.
LONG HAIR – Long, fine, thick, silky hair.
LONG HAIR SATIN – Long, fine, thick, silky hair with a Satin sheen.
FRIZZIE – Very dense, tightly waved or frizzed hair over entire body. Curly whiskers.
FRIZZIE SATIN – Tightly waved or frizzed hair with a Satin sheen. Curly whiskers.
HAIRLESS – Pink, thin, bright, translucent skin, free of scars or pimples. No hair.


Within each Variety, mice are grouped into five Sections by color and body markings.


Entire body consists of the same uniform color. They are: Beige, Black, Blue, Champagne, Chocolate, Coffee, Cream, Dove, Fawn, Gold, Ivory, Lilac, Orange, Red, Silver, White.


Both have the top color in any recognized color, with a contrasting underside: a rich golden-red tan in the TAN, a near white in the FOX. There is a clear and distinct line between the top and bottom color, running in a straight line along sides, chest and jaws.


There are nine groups within this Section, named according to the pattern of their markings, in any of the recognized colors:
Banded have a white band circling their body at their middle.
Broken Marked have as many colored spots or patches as possible, irregularly placed on a white background.
Broken Merle are Merle mice with white patches added.
Dutch have markings like the Dutch rabbit.
Even Marked have a uniform pattern, with clear cut and balanced spots or patches on a white background.
Hereford has a white face.
Rump White has a white rump marking.
Spotted Tans can be any of the Marked group, but those spots running into the belly area to be a rich, golden-red tan.
Variegated have small and numerous color splashes on a white background, distributed over the entire body, free from any solid, clear-cut markings.
