F1 generation Savannahs are very difficult to produce, due to the significant difference in gestation periods between the serval and a domestic cat (75 days for a serval and 65 days for a domestic cat) and incompatibilities between the two species' sex chromosomes. Pregnancies are often absorbed or aborted, or kittens are born prematurely.
Gestation lasts for 72–78 days. [9] Most births occur between December and May. Litters consist of one to three kittens, and one or two is more common. [10] The kittens are born blind and helpless, weighing about 65 to 95 g (2.3 to 3.4 oz), and develop rather slowly compared to the domestic cat.
Some species, such as cats, cows and domestic pigs, are polyestrous, meaning that they can go into heat several times per year. Seasonally polyestrous animals or seasonal breeders have more than one estrous cycle during a specific time of the year and can be divided into short-day and long-day breeders:
List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry it can predict established traits (phenotypes) of the offspring of particular crosses. In medical genetics, cat models are occasionally used to discover the function of homologous human disease genes. The domesticated cat and its closest wild ...
A pair of sibling kittens from the same litter at 11 weeks old. Kitten playing in a Tokyo pet shop. A feline litter usually consists of two to five kittens, [ 3 ] but litters with one to more than ten are known. [ 4 ] Kittens are typically born after a gestation lasting between 64 and 67 days, with an average length of 66 days. [ 3 ]
By 1948, she was one of three breeders independently crossing the Persian and Siamese to create the Himalayan cat. [3] Separate US-based breeding efforts had begun around 1950, [2] and a breeder known to sources simply as Mrs. Goforth received breed recognition from the Cat Fanciers' Association (CFA) near the end of 1957 for the Himalayan.
