How it works
  • Searches
    Enter a name or part of a name in the text field and press the Search button.
    The search is not case sensitive.
    When a exact match is not found it will try to match using the search string as part of the name.
    Which part of the name depends on the buttons "Starts with", "Ends with" and "Includes".

  • List dead ends
    Enter part of a name in the text field and press the "List dead ends" button.
    The search is not case sensitive.
    For instance with "Starts with" selected and Casa Gatos in the text field all dead ends starting with Casa Gatos will be listed.

  • Wildcards
    ?
    To match any character on a specific location in the seach string use ?.
    a?i will match aai, abi, aci, etc. ?ose will match bose, rose, nose......
    *
    To match any number of characters use *
    b*o will match bambino and bio or brothers porto folio
     
  • Genotypes
    Fx RB Foundation
    Historical identifier showing how the breed was developed. RB Foundation refers to the original crosses used to develop the Russian Blue in the late 1800s and early 1900s as well as the post-World War II outcrosses used to maintain the genetic viability of the breed. Fx indicates how many generations the cat is from the original foundation cat where x = the number of generations back.
    Muscovy
    Some breeders have crossed to domestic shorthairs to introduce different colors. The standards for the majority of associations worldwide state blue only; a few recognize different colors as experimental; and a handful recognize them for championship competition. In this database the term Muscovy is used as the genotype descriptor for these cats to record their background. Muscovy was chosen as a genotype name as it is a region of Russia, MUS is used in the EMS field as it is close to the RUS breed code.
    FxM
    Records the historical genotype of the cat. M indicates a color other than blue in the pedigree and Fx indicates the number of generations back the non-blue cat occurs where x = the number of generations.
    Nebelung
    Some breeders have chosen to use the Russian Blue as an outcross for developing a longhair blue cat known as the Nebelung. Some of the newer registries allow the shorthaired offspring of these cats to be registered as Russian Blues even though they may carry the longhair gene--some of these registries use VAR to indicate the shorthaired blue carries the longhair gene. In some registries, these shorthaired blue offspring are registered as Nebelungs because they could carry the longhair gene. In this database cats that have a longhair behind them are designated with a genotype of Nebelung. Cats that are known longhair carriers are identified with a genotype of Nebelung as well even though we may not know how far back the LH gene entered the gene pool. Some registries may have a cat registered as a Russian Blue even though its pedigree indicates it has a Nebelung (or Longhair) genotype--the cats are recorded here by their genotype.
    FxN
    Records the historical genotype of the cat. N indicates a longhair or longhair carrier appears in the pedigree and Fx indicates the number of generations back the longhair cat occurs where x = the number of generations.
    Eastern European cats
    The Russian Blue was historically important in the Eastern European countries however during the Communist era there was little to no breeding of pedigreed cats. Today the interest in the cat fancy is in full swing including the long-beloved Russian Blue. In some cases, blue domestic shorthairs have been used to help develop the breed in these countries. We are tracking the influx of these cats for historical and health reasons. Some of them have introduced the longhair gene accidentally and this database classifies them as Nebelungs. Whenever new cats are introduced to a stable gene pool there is the potential to introduce recessive deleterious genes so we track these cats in case a problem develops later on. To date, we have not identified any health problems associated with these cats.
    FxE
    Records the historical genotype of the Eastern European cats where E stands for Eastern Europe and FxE indicates the number of generations back that the Eastern European cat was introduced where x = the number of generations.
    Outcross Combinations
    For completeness we have recorded combined genotypes. FxME, FxNE, FxMN, and FxMNE record the historical genotype of cats with ancestry includes cats which are not considered part of the traditional Russian Blue breed pool. Fxyy indicates the number of generations back that the non-standard cat was introduced where x = the number of generations and yy = the combination of new genes that have been introduced..
