Badger (Shown in Berkshire / Badger Class)

As much of the underside of the rat as possible to be white, including belly, chest,
throat and underside of the legs, the white not to extend up the sides of the body.
Back feet to be white to the ankle, forelegs to be white to the elbow. Tail to be
white to half its length. The body colour shall conform to a recognised colour variety.
The white area shall be pure and devoid of any colour or staining. The defining
feature of this variety is the blaze. This is to be a wedge shaped symmetrical blaze
of white starting at the nose and extending up the face to the forehead. The blaze
to cover the whisker bed and taper to a fine point midway between the eyes and the
ears. Markings not to extend onto the cheeks or the eyes. Genetics: many possible |

Irish

White equilateral triangle on chest with front feet white and back feet white to
half their length. The triangle to be of good size, clear cut and devoid of brindling,
not to extend in a streak down the belly but to occupy all the space between the
front legs. The body colour shall conform to a recognised colour variety. Genetics: Hh or Hhi + other marked genes |

Hooded
|
The hood shall be unbroken, covering the head, throat, chest and shoulders, except
in the case of light coloured hooded varieties where a pale coloured throat and
chest is permissible. The hood shall be continuous with the saddle spinal stripe
which should extend down the spine to the tail, with as much of the tail as possible
being coloured. The saddle width shall be a quarter to half an inch in length (nearer
one quarter) - it must be as even as possible and unbroken. The edges of the hood
and saddle shall be clear cut and devoid of brindling. The white area shall be pure
and devoid of any yellowish tinge or staining. Genetics: hh or hml |

Variegated
|
The head and shoulders to be of a distinct colour with a white spot or blaze on
the forehead. Where a spot is present this should be centrally placed on the forehead,
round or oval in shape and no bigger than the rat's eye. Blazes are a wedge shaped
symmetrical blaze of white starting at the nose and extending up the face to the
forehead. The blaze to cover the whisker bed and taper to a fine point midway between
the eyes and the ears. Markings not to extend onto the cheeks or the eyes. The rest
of the upper portion (back, sides and tail) of the rat's body to be white, evenly
marked with patches and flecks of distinct colour, the colour to conform to a recognised
colour variety. Underside (including belly, chest and throat) to be white, devoid
of creamy tinge or staining. Genetics: hhe or hehe |

Capped
|
The colour not to extend past the ears and to follow the line of the lower jaw bone,
it should not extend under the chin. A white blaze or spot on the face, and the

Essex (Blazed Essex also shown in Essex Class)
|
To be recognised in any standard colour, remembering that the effect of the gene
responsible is to lighten the top colour. The darkest area is along the spine, becoming
less intense down the sides of the animal. The gradual fading of colour continues
onto the belly which is off white, with no spotting of darker colour. 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 colour. Pied tails not to be penalised.
A head spot or blaze 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 * |

Chinchilla
|
Top colour grey, caused by the intermingling of black guard hairs over a pearl white
ground. The whole to give a sparkling appearance. Undercolour dark slate blue, intermediate
portion pearl, tips black. All the underside to be white with a clear demarcation
between top colour and belly. Head markings may be present or absent. Where present
either a blaze or a spot to be acceptable. The standard for both is as follows: Head spot. Head spots to be centrally placed on the rat's forehead and no bigger than the rat's eye. Blaze. This is to be a wedge shaped symmetrical blaze of white starting at the nose and extending up the face to the forehead. The blaze to cover the whisker bed and to taper to a fine point midway between the eyes and the ears. Markings not to extend onto the cheeks or the eyes. Forelegs to be white to half their length, back feet white to the ankle (hock or tarsal bone). Tails to be pied. Faults: Drags, yellow or brown tinge to the top colour, skewed or misshapen blazes, uneven or over large head spots. Genetics:Not known but probably caused by the interaction of at least two marked genes, at least one of which is a lethal dominant. |

Roan (Shown in Roan / Striped Roan Class)
|
A strikingly marked bi-colour variety, with roan colouration, symmetry and contrast
being important impressions. Clearly distinct from existing marked varieties. Roans
are born solid coloured, but from the age of about 4-6 weeks they start to exhibit
roaning. This is a steady increase in the amount of white hairs intermingled with the solid colour, starting with the face, sides and tail root on the juvenile, then working its way up to the nape of the neck with the moult. With each moult the rat becomes progressively lighter, the final effect not really complete until the rat is well into adulthood. The roan effect is most pronounced on the face, around the rump and the sides. Pattern: The Roan shall have as symmetrical markings as possible. The underside should be completely white. Head: A wide inverted V shaped blaze, including the whisker bed, coming as close to the eyes as possible without touching the eyes, and coning to a point between the ears. Jaw line and underside of the head must be white. Eye colour to conform to base colour standard. Body: From the head, the colour runs back covering the ears and continues along the body extending down the sides. Belly to be white. Tail: Unmarked tail preferred. Faults: White spots in coloured fur/ coloured spots in white fur. Brindled demarcation line. Lack of white on face and head or a completely white face or head. Genetics: Due to an unproven recessive gene not on the H locus with the amount of colour controlled by modifiers. |

Striped Roan (Shown in Roan / Striped Roan Class)
|
A strikingly marked bi-colour variety with roan colouration, symmetry and contrast
being important impressions. Clearly distinct from existing marked varieties.
Pattern: The striped Roan shall have as symmetrical markings as possible. The chest, belly, sides and all the legs to be completely white. Head: A wide inverted V shaped blaze including the whisker bed, coming as close to the eyes as possible without touching the eyes, and coming to a point between the ears. Jaw line and underside of the head must be white. Eye colour to conform to the standard for the base colour. Body: From the head, the colour runs back covering the ears and continues along the body with no suggestion of a hood, in an unbroken horizontal stripe, symmetrical and as straight as possible. The stripe to be approximately 5cm wide. Demarcation shall be as clear cut and even as possible. Tail: Unmarked preferred. Faults: White spots in coloured fur/coloured spots in white fur. Brindled demarcation line, demarcation line too low. Lack of white on face or a completely white face. Stripe too narrow or broken, any suggestions of a hood. Genetics: Due to an unproven recessive gene not on the H locus with the amount of colour controlled by modifiers. |
