The NARR does not maintain rat standards.  Check the standards of your preferred club for descriptions of the color or marking.  For colors/markings, the NARR does not limit registration to those listed below, however, colors/markings must be acknowledged (standardized or unstandardized) by at least one recognized rat organization. Currently, those organizations recognized by NARR are Rat Society of America (RSA), American Fancy Rat & Mouse Association (AFRMA), RatsPacNW, and National Fancy Rat Society (NFRS). If you know of and use another recognized organizations for your standards, please submit this information to info at ratregistry dot org. A list of current standards from the above organizations is available upon request.

For descriptive purposes marked Siamese rats should be registered with the pattern listed.  ie... Seal Point Siamese Hooded Dumbo rather than Seal Point Triamese.  Using the marking gives far more background on the breeding of the rat. If you are registering a rat that does not fall into a standard or provisional that is accepted by a recognized organization, please register your rat with the closest marking, noting it as a mismark. ie... Black Cap Stripe Rex would be registered as Black Hooded (mismarked) Rex. For colors or color patterns not recognized by an organization, use the genotype to determine color or color combinations rather than phenotype. For clarification or questions, contact your preferred organization to find how your rat best fits the standards, or suggest a new standard.
