The long and slender appearance of the Savannah cat gives the impression that the animal is bigger than they weigh. Size is very dependent on generation and gender. Male F1 cats (Filial 1) are cats of the first generation which are normally the largest. F1 and F2 cats are bigger than subsequent generations because with them the genetic influence of the African serval as an ancestor is much bigger than with later generations.
Male Savannahs are bigger than females. The first generations can weigh 9 kilo or more and F2 and F3 neutered cats can weigh the most, but these are exceptions. Later generations usually weigh between 3 and 13 kilograms. Because different factors influence genes, Savannah cats can vary in size and weight, even in one litter.
The coat of a Savannah depends on the domesticated cat used for cross breeding. Previous generations have a kind of black dots on a lighter coat. The TICA breeding standard describe a brown dotted stripe pattern (cold to warm brown, tinted or gold with black or dark brown dots) and a black smoke (black dotted silver with black dots).
In general, the appearance of individual Savannah strongly depends on the generation, The feral appearance of a Savannah is caused by the presence of many Serval distinguishing features. The most prominent features are the different color patterns, the long body, the width of the animal, the standing ears, the very long legs, the thick swollen nose and the sunken eyes.
The body of the Savannah is long and long-legged when a Savannah stands. His buttocks are often higher than his shoulders. The small head is longer than wide and stands on a long slender neck. A male Savannah usually weighs about ten kilograms, while the females weigh about eight kilograms.
The back of the ears of the Savannah have eye spots. A central light stripe bordered by black, dark gray or brown hairs provide this eye-like effect. The short tail has black rings, with a firm black tip. The eyes are blue when kitten (like other cat species) and can become green, brown, gold or a mixed shade when adult.
