F7s are priced at $1000-1200 as pets.
All the kittens in the last F7 litter have been sold, and have gone to their new homes. Check back in a few months to see if we are expecting another F7 litter.
(Note: some breeders market kittens based on the % serval in a kitten, however the actual % of serval genes in a cat is a theoretical estimate, it is impossible to accurately calculate this number due to the way genes and chromosomes are inherited. This is especially true in later generation kittens that have multiple generations of savannahs behind them; it is impossible to even guess the % serval because the serval & domestic genes get recombined & reassorted at every generation (thoroughly mixing the genes up).
