Asked how many takes pregnancy in cats in the literature is given a precise answer: "The average length of pregnancy in cats is nine weeks." But this is only conditional numbers (and nine months in humans). In the normal course of pregnancy cat bears offspring from fifty-eight to seventy-two days. What determines the different stages of pregnancy, and how it takes place? Let's face it.
Different stages of pregnancy
Firstly, there is a perception that short-haired and long-haired cats are different stages of pregnancy. Although scientific evidence to this fact is not found, it is the place to be. For example, it is noted that usually (but not always), long-haired cats Kittens hatching longer. They have a gestation period of sixty-three to seventy-two days. Shorthair expect the appearance of offspring born from fifty-eight to sixty-eight days. A Siamese and Abyssinian cats (allegedly!) Hatching kittens longer than usual.
Gestational cats depends on the number of hatched and kittens. Most often large litters can become a cause of a shorter duration of pregnancy. And if the cat bears more than five kittens, then she gives birth to them before the average date. However, even the birth of a very large litter (eight to twelve kittens), which began before the bottom strap pregnancy (less than 58 days) are considered pathology. And such premature kittens often do not survive.
Cause prolonged pregnancy can and a small number of pups per litter, and stress on a pregnant cat in the last period of gestation kittens. At the same time delay childbirth for one week it is permissible and does not affect the health of newborns. However, a long delay requires human intervention, otherwise it may result in failure. But in any case, to control the timing of pregnancy can host only when he knows the exact date of mating and therefore conception, which takes place a day or two after pairing. It is a "point of reference" in pregnancy.

Interesting! If placental villi one to straighten, their area is five square meters. If during this period will intertwine placental villi opposite-sex kittens, then the light will be false hermaphrodites.
By the fifteenth day of pregnancy, the embryo reaches a size of two to ten millimeters. He becomes visible head, and there are the beginnings of the brain. By the eighteenth day of legs begin to form. Prior to the twenty-first day of pregnancy formed the beginnings of the auditory canals, the future appears pigmentation eyes, begin to develop internal organs. It was at this time becomes a first outward signs of pregnancy: a cat and turn pink nipples grow.

First, the embryo is formed by the upper lip, ear lobes and fingers. Continue to develop the skeleton, muscles, and internal reproductive organs. Formed spinal cord, jaw, tongue, palate. Hormonal system begins to develop.
By the end of the second trimester of the muzzle is formed: there are cheeks, chin, nose and mouth. Bones begin to suck the calcium and the teeth are formed (in the back of the jaw).

The last stage of pregnancy the cat. At the beginning of this period, the fruit grows to eight centimeters. The skin becomes thicker and gathers in folds, increasing the ears, and elongated tail. For forty-fourth day appears silky fur, and four days later it acquires the color. At this time, the fetus grows has to twelve centimeters.
On the fifty-eighth day of the formation of the fetus is considered complete, and all the remaining days precede birth. For twelve hours (or even days) before delivery cats rectal temperature drops to thirty-seven and a half degrees, and the prenatal period can last up to one and a half days.
Post Scriptum

However, successfully proceeding pregnancy in cats can not last longer than seventy-two days, and less than fifty-eight. On average, a cat bears posterity two months. And what is interesting!
