Not everyone knows about this animal. But once you know, Savannah cats are not easy for you to be a person who understands them, but must bring as many surprises as possible.
The Savannah cat is a crossbreed cat. It is the result of crossbreeding between a prairie lynx and a domestic cat. In 2001 the International Cat Association (TICA) recognized the Savannah Cat as a new, registered, and registered cat breed.
Since its inception, Savannah cats have shown themselves to be healthier and more agile than other cats. There are many different hybrids, but TICA had to admit that the Savannah cat was the champion cat in May 2012.
The most recognizable feature of a Savannah cat is its prominent long and pointed ears. They are tall and slender. Parts of their body, such as legs, tail, neck, are slim and small. Besides, Savannah cats’ eyes are sharp and have a “boomerang” shape. Slanted eyes are covered with little eyebrows that help protect them from the blinding sun. In particular, on the small and long face of that cat, the only attraction and makes a unique difference is the dark-colored rashes running from the corner of the eye, along with the wings of the nose, down to the mustache. Combined with spotted or striped fur, the Savannah cats look like real cheetahs.
Reproduction Characteristics Of Savannah Cat
Savannah cats can be very picky about their mates, and although they usually do not mate with domestic cats, they must do so by nature to give birth to a small Savannah cat. There are still schools when Savannah cats mate. They are the next Savannah cats.
Savannah F1 inherits the most prominent features of the first Savannah cat. And from this generation, breeding in this breed is quite tricky. Because they are hybrids, meanwhile, there is a distinct difference between the period of pregnancy of domestic cats and Savannah cats (15 days difference). In addition, sex chromosomes or genetic genes are also a factor to consider.
Being a crossbreed cat, therefore, the Savannah cat exhibits some sterility in reproduction. That trait represents male Savannah cats. They are sterile until generation F5 or more, although females can reproduce from the F1 generation.
Why Are Male Savannah Cats Sterile?
The male Savannah cats are sterile until they are one of the specific Fs. As noted, the F4 males are still fertile but very rare. Only about 50% of Savannah males can reproduce with certainty. And by the time of the F6, they were used for breeding programs.
So, why are male savannah cats sterile? The male cats are the regulators of sexual intercourse. Therefore, their genes may be affected by heterogametic (non-homogeneous sex chromosomes). That leads to a lack of recombination on the chromosomes. While the females still have recombinants, they can even reproduce from the F1 generation.
However, in 2011, researchers and breeders realized the possibility of changing infertility in the F5 generation males. They take into account the genetic and chromosome traits found in cats of both Savannah parents (one of them may be the F1 generation of a hybrid between a Savannah cat and a domestic cat). It also is in SBT cats (You can read and understand it in the reference source at the end of the article).
