AFRMA Fancy Rats - Non-Recognized Colors, Markings, & Coats

Some miscellaneous colors and markings of rats that have been produced by AFRMA breeders/seen at AFRMA shows but never standardized. There are many more out there.

See the AFRMA Official Color Standards Rat book for more.

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.

COLORS
AGOUTI POINT SIAMESE - An agouti version of Seal Point Siamese but with agouti points rather than rich dark sepia points. Eye color is red.

Genetics: A– chch

Note: At quick glance they look like a Seal Point Siamese but on close inspection they lack the foot color due to the agouti color. Used with Agouti Burmese breedings. This is a color that will not be standardized.

Silver Rat
MELANISTIC - Color looks like a black agouti. Color is black on the back fading down the sides into the belly into a grayish-tan color with black ticking. The white belly markings on these particular rats were down at the bottom instead of the top or middle like normal markings, unknown if that was a result of the color gene.

Genetics: am?? (melanistic agouti?)

Note: a.k.a. Shadow, Mock Agouti

SIAMESE SABLE - Body color to be a light brown similar to the Burmese gradually and evenly shaded over saddle and hindquarters towards the belly, being darkest at base of tail. Tail color to extend down the length of the tail. Belly color to be light brown. The points (nose, ears, feet, tail, and tail-root), which are a very dark brown, are as for the Seal Point Siamese. Eye color is red or light ruby. Siamese Sable to be shown only in AOCP class.

SPOTTED TABBY/MARBLE
Color is gray with black markings/pattern which consists of a dorsal stripe and spots on the sides and face (most spots run together as adult). Not to be confused with Merle. Other colors possible. The color of the dorsal stripe/spots is the base color, i.e. a Black Spotted Tabby has black stripe/spots and the gene dilutes the body color making a gray background.

Genetics: unknown (dominant gene)

Note: Breeders reporting tooth issues, lighter color teeth, megacolon in some, and failure to thrive in some litters. May have skeletal issues (one had a kinky tail). Not to be standardized with these issues; breeders are working to see if the problems are part of the gene that makes this pattern (Varitint-waddler gene in mice are tri-colored/calico colored but have an inner ear defect that makes them spin in circles/waltzers).

Originated at New England Reptile Distributors (NERD).

Spotted Tabby/Marble Kitten Rats
Spotted Tabby/Marble 14-day-old kittens showing their dorsal stripe and spots on the sides. The spots tend to not be as distinct (more run together) when they have a full coat. There is a Pearl in the middle and a Mink on the R side that were foster kids and a plain Russian Blue Berkshire top R. There is also a very pale colored Spotted Tabby on top. Rats owned and bred by Jozzette Hagemann. Photo ©2016 Karen Robbins.
SILVER CINNAMON - Color is a warm russet brown, with medium slate at the base of the hair. Coat is evenly ticked with chocolate. Belly color to be as agouti, but of a lighter shade. The coat should contain equal numbers of silvered and non-silvered hairs. Each silvered hair to have as much of its length white as possible–a colored tip to be allowed. Silvering to give an overall sparkling appearance. Eye color is black.

Genetics: A– mm

Note: Usually seen in Cinnamon Pearl breedings that then lose all their silvering in adulthood.

Silver Cinnamon Rat
MARTEN - [Black] Body Colour to be similar in shade to an HB lead pencil, some fading to be expected in an adult. Some light heathering to be expected. Fur on the face to be lighter on the whisker bed, over the eyes and behind the ears. Belly colour a slightly paler shade of grey than the top. Foot colour to match top. Eyes pink or black.

[Agouti; called Silver Agouti in N.F.R.S.] To be a mix of mid grey ticking over a pale ivory ground, with no suggestion of blue or brown tones. Ticking to be darkest along the back and to fade down the sides to the pale ivory belly. Fur on the face to be lighter on the whisker bed and around the eyes. Eyes pink or black.

Faults: rusty patches, white toes or patches, darker points on the nose, tail root or feet. (N.F.R.S.)

Genetics: unknown (dominant gene)

Note: Discovered in 2008 by Rene Bastiaans, the Netherlands, from German/laboratory stock, called RED (red-eyed devil); England imported stock in 2010 and gave the name Marten. Color lightens with age. Darker colors show off coloring best, lost on pale colors. Common for marbling on the head. Can be combined with the Black eyes of the Ivory/B.E. Siamese/Burmese colors to make a B.E. Marten.

FROSTED - Frosted rats will have the tips of the hairs white but will not get more white as they age. Not to be confused with silvered, Roan, or Silvermane/d’Argent.

Genetics: unknown (dominant gene)

Note: Frosted came from feeder stock in CA, 2014.

Color similar to Silvermane that originated from pet shop/feeder stock by Derek Berrier/Jessica Jones Cashwell, Kadru’s Clutch, Hampstead, NC, 2012. Silvermane rats are similar to Roan in that they will get more white as they age; however, rather than having silvered and non-silvered hairs, their coat will have the tips that look white. White tips disappear when wet just showing the dark undercoat. Silvermane rats are similar to d’Argent rabbits. Not to be confused with silvered, Roan, or Frosted.
