A Savannah cat is a cross between a domestic cat and the serval, a medium-sized, large-eared wild African cat. The unusual cross became popular among breeders at the end of the 1990s.

  The first known Savannah was born April 7, 1986 when a female a Siamese (domestic cat) gave birth to a kitten sired by an African Serval. This F1 (first generation hybrid cross) was the first on record. This unusual female kitten had both domestic and Serval like traits. Both the kitten and breed were ( named "Savannah").

  Patrick Kelly heard about Savannah and decided he wanted to try to develop a new breed. He persuaded a breeder, Joyce Sroufe, to join him in his efforts. In 1996, Patrick Kelley and Joyce Sroufe wrote the original version of the Savannah breed standard and presented it to the board of The International Cat Association. TICA accepted the Savannah for registration in 2001. In May 2012, TICA accepted it as a championship breed. 
  Generation  Numbers and Letters?

“F” designations in Savannah Cats tells us how many generations removed from the African Serval ancestry. ​
F1 = Serval is the Father/Mother of the kitten (62.5% serval)
F2 = Serval is the Grand father/mother of the kitten (25% serval)
F3=Serval is the Great Grand Father/mother of the kitten (2.5% Serval) etc..

  A, B, C, SBT
 "A" One of the parents of the kitten is NOT a Savannah (savannah and serval)
"B" Both parents of the kitten are Savannahs (savannah A and savannah male)
"C" Parents and grand parents are Savannahs (savannah B and savannah male)
"SBT" Parents, grand parents and great grand parents are Savannahs (savannah C and savannah male)

Male savannahs are sterile at least an F4 and only a few F4 fertile males exist. About 50% of the F5 males are fertile, there for many use an F6 male for their breeding programs.

 SBT is the only generation that can be shown... 3 generations of Savannah to Savannah pairing.

  The cats are commonly compared to dogs in their loyalty, and they will follow their owners around the house like a canine. They can also be trained to walk on a leash and to fetch.

  Some Savannahs are reported to be very social and friendly with new people and other cats and dogs, while others may run and hide or revert to hissing and growling when seeing a stranger. Exposure to other people and pets is most likely the key factor in sociability as Savannah kittens grow up.  An often-noted trait of the Savannah is its jumping ability. They are known to jump on top of doors, refrigerators and high cabinets. Some Savannahs can leap about 8 feet (2.5 m) high from a standing position. Savannahs are very inquisitive. They often learn how to open doors and cupboards, and anyone buying a Savannah will likely need to take special precautions to prevent the cat from getting into trouble.

  Many Savannah cats do not fear water, and will play or even immerse themselves in water. Some owners even shower with their Savannah cats. Presenting a water bowl to a Savannah may also prove a challenge, as some will promptly begin to "bat" all the water out of the bowl until it is empty, using their front paws.

  Another quirk Savannahs have is to fluff out the base of their tails in a greeting gesture. This is not to be confused with the fluffing of fur along the back and full length of the tail in fear. Savannahs will also often flick or wag their tails in excitement or pleasure.

  Vocally, Savannahs may either chirp like their serval fathers, meow like their domestic mothers, both chirp and meow, or sometimes produce sounds which are a mixture of the two. Chirping is observed more often in earlier generations. Savannahs may also "hiss"—a serval-like hiss quite different from a domestic cat's hiss, sounding more like a very loud snake. It can be alarming to humans not acquainted to such a sound coming from a cat.

  Probably the most influential factor is early socialization. Kittens socialized with human contact from birth and human interaction each day reinforces kitten and cat human interaction behavior that lasts throughout the cats life span. Kittens within litters will tend to have varied social skills with some that like human interaction and others that fear it. If kittens that fear humans never grow past that fear they will tend to exhibit a more shy behavior and are likely to hide when strangers are present. Kittens that look forward to human visits and likely to engage in play with humans tend to grow to cats that are more welcoming of strangers and less frightened of new environments. These cats tend to become the life of the party versus a cat that will find a hiding place until the party is over. Human cat socialization should be practiced each day with positive reinforcement for a kitten to grow into a well rounded social Savannah cat. Kittens that go for long periods of time without human interaction and only interact with their mothers or siblings usually do not develop a strong bond with humans and tend to be less trusting of humans. These kittens tend to be shy and are likely to hide when unknown people are present.
