What Does The F Rating Mean For Savannah Cats?

If you’re thinking about getting a Savannah cat, then you probably want to know that the cat will make a good pet. The F rating is the most important part of any breeding program for these cats.

SAVANNAH CAT 101 / Everything You Need To KNOW
Savannah cats are classified using an “F” rating system, which indicates the number of generations removed from their wild ancestors.
The “F” rating ranges from F1 to F7, with F1 being the closest to the wild serval and F7 being the furthest.
F1 Savannah cats have a higher percentage of serval heritage and exhibit more wild characteristics.
The higher the “F” number, the more domesticated and closer to a typical house cat Savannah cats become.
F1 and F2 Savannah cats require more specialized care and experience due to their higher percentage of wild genes.
F3 and beyond Savannah cats are generally more suitable for first-time owners and families.
The F-rating system helps prospective owners understand the temperament and characteristics of Savannah cats based on their generational status.

These Are The Basic Ratings Used In Breedings

The F rating is a way of gauging how inbred a Savannah cat is. The higher the number, the closer that particular Savannah cat’s lineage is to other Savannah cats and wild servals. 

An F5 or higher may have health issues and can be prone to temperament problems. This means that if you’re looking to purchase one of these cats, it’s important to research where they came from and make sure they have been bred responsibly.

F1 means that the cat is a first generation Savannah cat. F1 cats have been bred from a domestic cat and a Serval, which are wild African animals. 

F1 Savannah cats are very rare, and expensive. They are not recommended for families with children as they can be very aggressive towards other pets, particularly dogs and rabbits.

F2 Savannahs are the result of breeding two F1s together. Because the F2 is technically just a hybrid, it does not have any special health risks beyond those of purebred cats. The F2 generation usually has more wild traits than the first generation and are generally larger in size than their domestic parents.

F3 cats are the third generation of Savannah kittens bred from F1 parents. As you can probably tell by now, F3 Savannah cats are a lot different than their wild ancestors and have almost no physical resemblance to them.

The F3 generation is often referred to as the “middle ground” of domestic Savannah cats because they are bred to be more domestic than F1 and F2 cats, but still retain some wild traits. While this means that your pet will likely be more tame than a purebred cat or dog, it also means that they may not be as friendly towards people or other pets as other breeds might be.

F3 kittens tend to be larger in size than both their wild counterparts and first generation Savannahs (F1). 

However, unlike second generation Savannahs (F2), they tend not to be quite as large or muscular compared to purebred pets of similar size like Maine Coon cats or Cocker Spaniels for example.

F4 Savannah cats are bred from two F1s, which means they have one purebred (F1) parent and one semi-domestic (F2) parent. 

The F4 Savannah cat is considered to be the most stable of the Savannah breeds, and are less likely to have health problems than F5 cats.

The F rating is not as commonly seen as the other ratings. It means that a cat is a hybrid, and not purebred. This means that it is not a crossbreed, but it isn’t necessarily the same thing as being bred in captivity or by humans. 

A Savannah F5 cat could have been born in the wild or have been bred by another Savannah owner, for example.

The F rating does not mean that your cat isn’t healthy or inferior to other Savannah cats—it just means he’s not 100% purebred from his parents’ side (most of us aren’t either).

F6 And Later Generations

F6 and later generations are not considered Savannah Cats. They are not eligible for registration, showing, or breeding with other F6 and later generation cats.

F6 and later generations cannot be registered as Savannah Cats because they do not meet the minimum of 75% African Serval ancestry that is required by the International Cat Association (TICA).
