How long does the pregnancy last in cats? How does it flow?
Each of us has a favorite among the “brothers” of our smaller – animals. And each has its own: one – dogs, another – rabbits, the third – cats, and so many can be enumerated. We do not just love them, we adore them, not only do they become members of our family and we are ready to do a lot for them, if not everything. Talk about cats today. Now it has become fashionable to sterilize cats, but all followers of this, and if your cat is not sterilized, the question may arise: so, how long does a cat’s pregnancy last, and how will it proceed? That’s exactly what we are trying to light.
Veterinarians and special literature on the question of pregnancy in cats answer: it lasts about nine weeks. As in all the rules, there are also exceptions: if the pregnancy proceeds normally, the cat can bear its offspring from fifty-six to seventy-five days. Why does this happen, and how will this pregnancy go with your beloved pet? Let’s try to figure it out.
Terms of pregnancy
Gestational age can be different, and it depends on many factors: a short-haired or long-haired cat, the number of kittens that a cat carries and many other reasons.
Veterinarians have noticed that cats with long hair (although not always) bear their offspring longer, their pregnancy can last up to seventy-five days. This is not scientifically proven, but this is not uncommon. Shorthair cats can give birth from fifty eight to sixty five days. But the Siamese and Abyssinian cats walk with kittens the longest.
As we used to say, the term of delivery may depend on the number of offspring. So it happens: the more kittens in cats (for example, more than five), the less she goes pregnant. But childbirth, which takes place before fifty-six days, even if a cat has a lot of kittens (from seven to twelve), will already be pathological. And mostly premature offspring can often die.
However, prolonged pregnancy happens with a small number of offspring. This can contribute to the stress that the cat experienced in the last days of pregnancy, unhealthy diet and a lot of different things. But the delay of labor for a week is quite acceptable and acceptable, such a delay in the birth of kittens will not affect. With a longer delay, veterinary intervention will be necessary to save the offspring. And the owner of an animal can know and keep control over pregnancy when he knows the date of mating. Conception occurs on the second day after mating, and this will be the beginning of your beloved cat’s pregnancy.
What is a cat pregnancy calendar
The pregnancy duration of a cat is divided into three phases.
After mating, fertilized zygotes (eggs) are implanted (attached) to the wall of the cat’s uterus and in the first week the fertilized cells will be in the amount of dust particles, the diameter of which will be three-tenths of a millimeter. Like any egg cell with an embryo, it looks like a small empty vial, inside which there is a bundle. The vial will then turn into a placenta, and the nodule will develop like an embryo.
– Interesting information: scientists have proven that, depending on the future
the sex of the kitten, the place of attachment of the egg is predetermined.
The development of each kitten occurs in the “chorion”, the so-called cocoon. Each cocoon is surrounded by its placenta, through which the fetus is nourished. The placenta itself is covered with villi as the growth rate of the fetus.
– Interesting information: the villi of the placenta is tightly twisted, and if their
straighten from one placenta, then its area can be up to five square
meters When weaving the villi of different placentas (rarely happens), they will be born
kittens are false hermaphrodites.
And only by the sixteenth day of pregnancy the kitten’s fetus will reach in the amount of about ten millimeters. At this time, the development of the head and brain buds occurs. Closer to the eighteenth day, the legs will begin to develop. By the twenty-first day of pregnancy of a cat, the germ of the auditory canal of the fetus is formed, the pigments of the future eye are born, and the development of the internal organs of the kitten begins. It is at this time that you can see signs of pregnancy: bright pink and enlarged nipples of the mammary glands become.
During this period of pregnancy, the embryo is already like a fetus and is being made by a small-small kitten. What happens to it: first, the upper lip begins to form in the embryo, the second, behind it, the earlobes and fingers on the paws, the third, the development of the skeleton, muscles, and genital and internal organs continues. And the hormonal system develops.
At the end of this trimester, the muzzle is formed: mouth, nose, cheeks and chin. The teeth are formed (in the deep part of the jaw), the bones are saturated with calcium. Proper placement of internal organs occurs, the head increases in size, then the eyelids appear, and small triangles of the ears.
