What do the Numbers and Letters Mean?

What do the Numbers Mean? (F1, F2, F3........)

Savannahs are the offspring of a Serval paired with a Domestic Cat (preferably a Savannah as that is the only TICA Permissible cross to produce Savannahs now that the breed has reached Championship status). The result of this pairing is an F1 based on the Hybrid Filial Generation, and is roughly 50+% Serval. If the F1 is bred back to a Domestic Cat, the result is an F2 which is theoretically 25+% Serval. An F2 bred to a Domestic Cat produces an F3 which is about 12+% Serval. Next generation would be an F4, with approximately 6+% Serval. After that would be an F5 at roughly 3+% Serval. This continues on down the line, the filial generation advancing by one every pairing. Once at the SBT level the Serval percentage stays roughly the same regardless of the Filial Generation since only Savannahs have been paired.

What do the Letters Mean? (A, B, C or SBT)

• If only one parent is a Savannah, this results in an "A" registered cat. (Including F1's since one parent is a Serval)
• If both parents are Savannahs, this results in a "B" registered cat.
• If both parents AND grandparents are Savannahs, the result is a "C" registered cat.
• Once parents, grandparents and great-grandparents are Savannah the result is an SBT (Stud Book Traditional). This is the first generation considered a purebred Savannah, and is the first generation eligible for Championship Competition with TICA. The earliest generation this can be achieved is F4 (but that does NOT mean ALL F4's are SBT).
