Some miscellaneous colors, markings, and coats of rats that have been produced by AFRMA breeders/seen at AFRMA shows but never standardized. There are many more out there. See Fancy Rat Genes for possible genetics.
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.
|VELVET - Coat 30, color 20
The coat to be soft, short, and plush similar to Rex rabbits. Russian Blue came from these rats; Blue-Beige, Silver Blue, Russian Fawn, Russian Silver, Russian Platinum came from Russian Blue; these colors have ticking/heathering and a different feel to their coats. Eye color to match base color.
[Accepted into Unstandardized July 18, 2009; removed from Accepted Proposed Unstd. December 1, 2012, and moved to Non-Recognized due to lack of entries.]
Genetics: unknown (bred as a recessive)
Note: Developed by Karla Barber from
very pale bluish beigerats shipped from the East Coast in 1987; coat doesn’t develop until adult; coat has minimal guard hairs so Agouti colors look like a different color than what they are.

|HARLEY - Has a sparse, fine, wispy coat with no undercoat that falls out easily. Reported that most lines have health/breeding issues so not likely to be standardized in AFRMA. If interested in breeding this variety, choose a line without any issues.
Genetics: unknown (recessive gene)
Note: Found in pet shop Sept. 1, 2002, by Debbi J. Needham, Odd Fellows Rattery (OFR), WA. Has a shiny coat like Satins.
Note from biologist Nicole Housel (11-14-20): Harley lacks the undercoat that normal furred rats typically have which can lead to an impression of a longer coat, even though the actual length is normal. They can have
singedlooking whiskers which further supports Harley is in fact not a long haired type. Whiskers are modified hairs and affected by hair coat genes the same way the rest of the coat is. The look of whiskers will be different due to the different structure, but they are still affected. Think of how Rex whiskers are curled... That being said, if Harley is a long-coated variety, then the whiskers should also be longer than normal. If the whiskers are in fact shorter, or otherwise same length (let’s assume shortening is due to breakage), then that supports that Harley itself is a normal or even short-length coat type. The singed look, along with shortening and crimping suggests the whiskers are actually more delicate than normal and prone to breakage. This goes along with Harley coats: they tend to be sparse, easily broken, and dry. Harley seems to make a more delicate fur type than normal fur mutations, which possibly goes along with some effect in the integumentary system in general (not just fur) since their skin also tends to be dry. Perhaps the mutation affects the sebaceous glands, not just the hairs.
