F1, F2 … What do all these numbers and letters mean?
F: Filial generation
This refers to how many generations removed a cat is from its African Serval ancestry. An F1 Savannah Cat is a first generation offspring and has a Serval parent (usually a Serval father and a domestic mom). An F2 is a second generation offspring with a Serval grandparent, an F3 is a third generation offspring with a Serval great grandparent, and so on.
Savannah generation filial numbers also have a letter showing the generation of Savannah + Savannah breeding.
A: one parent is a Savannah, the other parent is an outcross (for example, the Serval).
B: both parents are Savannahs; at least one parent is an A, and at least one grandparent on either side is an outcross.
C: both parents are B or better; at least one parent is a B, and at least one grandparent is an A.
SBT: Stud Book Tradition. The kitten has Savannah parents for at least three generations, and is considered a pure-bred Savannah Cat.
When breeding, the next generation of kittens will always follow the earlier generation parent. The letter designator will also follow the earliest letter. So, an A registered cat bred to a B registered cat will produce B registered kittens. Or an F1 bred to an F5 will produce F2 kittens. Thus, an F1A queen bred to F5B stud will produce F2B kittens. As another example, an F7C queen bred to the same F5B stud will produce F6C kittens. These letters may mean a lot to us breeders, but generally is of little importance when the kitten/cat is going to a pet home. The felial (F) numbers do, however, make a difference in the overall traits and personality of their kittens.
Savannahs are in the Championship class with TICA (The International Cat Association) starting Spring 2012, and with the CCA (Canadian Cat Association) starting Fall 2012, so only SBT level cats may be entered in shows. SBT starts at the F4 generation and usually ends at F7.
The Savannah is still a progressing breed and Savannah breeders are working hard to make the perfect standard. View a copy of the current Savannah Breed Standard by clicking here
