Understanding Savannah generations can be very complicated. Understanding percentages of generations can be even more confusing. Savannahs are the most expensive cat breed in the world It is extremely difficulty to produce, due to the significant difference in gestation periods between the serval and a domestic cat (75 days for a serval and 65 days for a domestic cat), and sex chromosomes. Many breeders have tried and failed producing F1 generation Savannahs. Many pregnancies are often absorbed or aborted, or kittens are born prematurely. Servals can be very picky in choosing mates, and often will not mate with a domestic cat. Many breeders raise the Serval in their homes, around their females to increase the chances of successful future breedings.
Here is a basic breakdown of generations and serval percentages:
F1 Serval Father and female breeding up to 75% in some cases 87.5% serval Always an “A”
F2 Domestic or cross male and F1 generation female, 25% to 37.5% serval can be an “A” or “B”
F3 F2 generation female and domestic or cross male 12.5% Serval can be an “A” “B” or “C”
F4 Domestic or cross male and F3 female- first generation considered “SBT” stud book traditional or “purebred”
F5 Savannah or male and F4 female
F6 Savannah or Male and F5 female
* Savannah males are typically sterile until the F5 generation. Their value greatly increases due to this being the first generation of Savannah males that can reproduce.*
SV x SV Savannah to Savannah breeding (SV is the TICA code for the Savannah breed)
SBT TICA standard as a purebred and “stud book traditional”
A means one parent is a Savannah and the other is an outcross.
B both parents are Savannahs with one of them being an A.
C designation is when both parents are Savannahs and one of them is a B
A x (any SV) = B
B x (B,C,SBT) = C
C x (C, SBT) = SBT TICA considers SBT pure breed
SBT x SBT= SBT
