Note: The pictures on this page are not meant to be true representatives of the animal’s color. Because of differences in monitors (CRT/LCD) and how the monitor is adjusted, the colors may be different. Seeing in person is always best.
ENGLISH IRISH - White equilateral triangle on chest with front feet white and back feet
white to half their length. The triangle on chest to be of good size, clear and devoid of
brindling, not to extend in a streak down the belly but occupying all the space between the front

IRISH - Irish rats may be shown in any recognized color. The top color is to be judged as to the
respective color. Distinctive markings are the white underside, with four white feet and a white tail
tip. The under marking should be a pure clean white, of moderate size and as even in shape as possible,
not extending onto the legs, sides, or chest. The white feet should resemble the stops on a Dutch
rabbit. The tail should be colored for most of its length, with a white tip of no more than one-fourth
of its total length.

BERKSHIRE - Berkshire rats may be shown in any recognized color. The top color is to be judged as
to the recognized color. Distinctive markings are the colored top with a completely white belly and white feet and tail, with a small white spot between the ears. There should be an even line between the top and

ESSEX - To be recognized in any standard color, remembering that the effect of the gene responsible is to lighten the top color. The darkest area is along the spine, becoming less intense down the sides of the animal. The gradual fading of color continues onto the belly which is off white, with no spotting of darker color. When viewed from above, the fading effect should be symmetrical, having no clear demarcation. The fading effect also to be seen on the legs so that the feet are also off white. There should be no obvious patches of contrasting color. Pied tails not to be penalized. A head spot is essential; this must be well defined, centrally placed on the forehead and symmetrical. Genetics: Unproven lethal dominant gene on H locus tentatively named Hro * (N.F.R.S.; accepted 4-30-05)

VARIEGATED - Variegated rats to be shown in any recognized color and are similar to Hooded
rats but instead of a spine marking, will have patches and flecks of color on the back side. The
head and shoulders to be solid like those of a Hooded rat with a white spot/star on the
forehead which should be centrally placed, round or oval in shape, and no bigger than the rat’s
eye. The variegation (patches and flecks of color) to evenly cover the rest of the white body from
the shoulders to the tail including the sides and tail. Underside (including belly, chest, and throat)
to be white, devoid of creamy tinge or staining. (Rev. 8-19-06)
