What is an F5 Savannah Cat?

F5 Savannahs are the great-great-great-grandchildren of the African serval, typically representing the fifth generation of hybrid breeding.

By this stage, nearly all F5s are SBT (Stud Book Tradition), meaning their parents, grandparents, and great-grandparents were all Savannahs—no recent outcrosses to other breeds. This makes them true purebred Savannah cats, fully recognized as domestic under TICA guidelines and eligible for the show ring.

F5s retain the exotic beauty of their ancestry—tall, lean, and boldly spotted—but tend to be gentler, more adaptable, and easier to integrate into a typical home environment. They’re known for being athletic, affectionate, social, and deeply bonded to their humans.

How Big Do F5 Savannahs Get?
F5s show some size variation depending on their bloodlines but are generally a bit smaller than F4s. Adult females typically weigh between 8 and 14 pounds; males often fall between 10 and 18 pounds. Some can grow larger, especially from big-bodied lines, but most land solidly in the “tall, leggy domestic” range—impressive, yet manageable.

As with any generation, no breeder can guarantee final size. However, patterns often emerge within established lineages, offering educated guesses based on previous litters.
