Understanding Savannah Cat Generations and Size Variations

The size of a full-grown Savannah cat primarily depends on its generation, denoted by "F" numbers. The lower the number, the more serval DNA the cat has, resulting in larger sizes.

F1 Savannah Cats: The Giants of the Breed

F1 Savannahs are the largest, with males typically weighing 17-25 pounds and standing 16-18 inches at the shoulder. These impressive cats can measure up to 24 inches from chest to rump, with some exceptional individuals reaching 30 pounds.

Mid-Generation Savannahs (F2-F3)

F2 males usually weigh between 13-16 pounds and stand around 14-15 inches tall. F3 Savannahs maintain significant size, with males weighing 14-20 pounds and reaching heights of 14-17 inches.

Later Generations (F4 and Beyond)

F4 and subsequent generations typically weigh between 10-18 pounds, comparable to large domestic breeds. These cats maintain the breed's distinctive appearance while being more similar in size to traditional house cats.

Savannah cats experience rapid growth during their first year of life. By three months, they can weigh between 2.8-9.7 pounds, depending on their generation. Most reach their full size by 18 months, though some may continue developing until age three.
