The size looks and behavior of Savannah pretty much depends on the generation of Savannah and the percentage of the African Serval blood. Therefore they are classified into generations. According to what generation the cat represents, they are marked by letter F (Filial) and numbers and letters A, B, C indicating the origin of breeding.
They are marked:
F1 – has no less than 50% of serval’s blood or one of the parents is a Serval;
F2 – has no less than 25% of serval’s blood or one of the grandfathers is a Serval;
F3 – has no less than 12.5% of serval’s blood, great-grandfather is Serval;
F4 – has no less than 6.25% of serval’s blood, great-great-grandfather is Serval;
F5 – has no less than 3.12% of serval’s blood, great-great-great-grandfather is Serval;
Letter A means one of the parents is not Savannah. B – grandparent. C – great-grandparent.
Cats, whose parents are Savannahs by three generations or more are marked SBT (stud book traditional) and can participate in exhibitions and compete with other cats.
F1 Savannah is the biggest cat. It can weigh up to 8-13kg and its height can be up to 42-55cm.
F2 Savannah weighs about 6-10kg, height – 35-45cm.
