The F3 generation has a serval great grandparent, and is at least 12.5% Serval. Serval ("Leptailurus serval") occurs widely in the crater. In Africa, predators include leopard, serval, caracal, ratel and large owl species. The serval and caracal also prey on this species. A servical is the cross between a male serval and a female caracal. It is a close relative of both the caracal and the serval. The serval also has melanistic forms in certain areas of East Africa. Savannah cats are known, but fertility is questionable at those percentage Serval levels. F2 Savannahs can be as high as 75% serval. A Savannah's exotic look is often due to the presence of many distinguishing serval characteristics. Savannahs are always A, since the father is a nondomestic outcross (the serval father). It is a cross between a serval and a domestic cat. Presumably, this is due to the higher serval percentage in C and SBT cats. The serval ("Leptailurus serval") is a wild cat native to Africa.
