The Savannah is an amalgam domestic cat breed. It is a cross between the serval and a domestic cat.
Savannahs are considered one of the larger breeds of domesticated cats. The savannah's tall and slim build gives the appearance of greater size than their actual weight. Size is very dependent on generation and sex, with F1 hybrid male cats usually being the largest. F1 hybrid and F2 hybrids are usually the largest, due to the stronger genetic influence of the African Serval ancestor.
A female F1 Savannah Cat named "Scarlett's Magic," measuring 43.43 centimeters or 17.1 inches from shoulder to toe, is the tallest cat in the world, according to the Guinness Book of World Records. Male Savannahs tend to be larger than females. It is possible for early generation Savannahs to weigh up to 20lbs or more, with the higher weight usually attributed to the F2 or F3 neutered males, though this is not the norm. Later generation Savannahs are usually between 10 to 15lbs. Because of the random factors in Savannah hybrid genetics, there can be significant variation in size, even in one litter.
Savannah’s prices range from $5,000 to $50,000, but the record-breaking elegant herself is not for sale.
