Savannahs have been allowed to show at TICA shows for several years in the Advanced New Breed (ANB) class, as long as they were at least a "C" cat (F3C, F4C, F5C....etc). As of May 1, 2012, Savannahs are now competing in all classes along with all other breeds of cats. Savannahs that are eligible to show must be at least an F4SBT, meaning they have a minimum of four generations of Savannahs as parents, grandparents and great-grandparents. Savannahs that are not eligible for show may be permitted to attend for "Exhibition Only". This can include F1-F3 cats, and Savannahs that don't have the proper color or pattern allowed for showing (the blue, cinnamon, chocolate, pointed (siamese coloring) and marble patterns) and non-permissible colored cats that are at least F4 can compete in the Household Pet (HHP) class or in the New Traits class. Now that Savannahs are showing as any other domestic breed they are doing very well! There are already several cats that have reached Champion status and beyond....
I believe most breeders of F1's have waiting lists. I assume by "hint of wild"----you are referring to a Savannah that most resembles a serval? We try to educate people not to use the word "wild" or "exotic" when referring to Savannahs, as that has lead to bans on ownership in some states and countries; and thinking that Savannahs are always huge is a myth we also try to dispel. Most Savannahs are the same size and weight as other domestic cats; the long legs, tall ears and lean body mass tends to make them appear larger than other cats. There are a few F1 female and F2 male Savannahs that are quite large, however. Generally, seeing what the parents or past litters from the same pairing will give a good indication of what a kitten may look like, and kittens can and do change appearance from babyhood to becoming an adult
If you can, attend a TICA show near you! It's a good place to meet breeders and see the cats:
