The NARR does not maintain rat standards.
Check the standards of your preferred
club for descriptions/genetics of colors or markings to determine the best
way to register your rat. For colors and markings,
the NARR does not
limit registration to those listed below. These are only examples. However, colors
and markings must be
acknowledged (standardized or provisional) by at least one recognized rat
organization. This is done in an effort to maintain uniform terms for
genetically known mutations and the combinations of them. Currently, those organizations
(and their standard terms) recognized by NARR are
Fancy Rat & Mouse Association (AFRMA),
Fancy Rat Society (NFRS),
Society of America (RSA),
and United Rat Standards Affiliation (URSA). If you know of and use another recognized
organization 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.
On occasion, you may come across a
genetic combination that is not a standard in one of these
organizations. If this is the case, there are two options for
If any organization decides to use
alternative terms for showing purposes, this is of no concern with NARR.
Registration will still occur with the preexisting nomenclature based on
genotype. Show terminology is up to each organization.
Example. Blue Beige = Russian Blue + Beige, but an organization may show the rat as Russian Beige, which is the same genetically.
For descriptive purposes, marked Siamese rats should be registered with the pattern. 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 Split Capped Rex would be registered as either Black Capped (mismarked) Rex or Black Blazed Capped Rex depending on the particular rat.
For clarification or questions, contact your preferred organization to find how your rat best fits the standards, or suggest a new standard or term.
