The Savannah cat is a tall, slim, long-legged cat and its final size may also depend on how close that particular offspring is to the first generation crosses – the early generations being quite large. Male Savannah cats tend to be larger than females. Because of the random factors in the Savannah cat breed's hybrid genetics, there can be significant variation in size, even in one litter. The overall look of an individual Savannah cat depends greatly on generation. They are usually spotted but can also come in classic or marble patterns, snow coloration and blue or other diluted colors. The ears are tall, deeply-cupped rounded and erect (the backs of the ears have a central light band bordered by black, dark grey or brown, giving an eye-like effect), they have a wide nose and hooded eyes. Their short tails have black rings, with a solid black tip and their eyes may be green, brown or gold.
