The self rat, genetically H/H, is also referred to as non-spotted (Roy Robinson, The Genetics of the Norway Rat). It is considered a marking but is actually a lack of (white) markings. A rat can be labeled a "self," however, it is the default marking, so when a rat is called, for example, a "black," it is understood that the black rat has no white markings or is a "black self." Rats in the registry won't be labeled as self. It is understood that they are not marked if there is no marking listed.

Self is recognized in all clubs that show rats. Common faults include white hairs on the body and/or white on the feet or toes. These may or may not be disqualifying faults depending on the club you are showing your rats with. For the purposes of NARR, if you are registering a self rat that has some fault (white feet), you can register this rat is a mismarked self if you prefer.
