Theoretical reproduction rate of cats

       It can be born for more than ten years, but don’t let it regenerate when it is too old, because the physical fitness of the baby will be bad if it is too old. In addition, when the big cat is old, it is easy to produce, and the lack of productivity will cause dystocia. I have seen a teenage old cat giving birth to a baby, but it almost died. I suggest that it should not be allowed to give birth

       When the male cat grows to 7-8 months old, the gonad begins to mature, and the male cat has the ability to breed offspring;

       When the female cat is about 6-8 months old, the follicles on the ovary begin to develop and ovulate, and the phenomenon of oestrus appears.

       The appropriate age for mating is usually sexual maturity, and then half a year later to reproduce offspring. Premature mating not only affects the body of female cats, but also produces fewer offspring, smaller individuals, weak physique, low survival rate, and even miscarriage, premature delivery, dystocia or abortion, and may directly affect the subsequent estrus interval, the success rate of mating and the number of litter, which is not worth the loss.

       It is helpful for the realization of eugenics and breeding to choose the right mating time for cats, which is good for cats themselves and future kittens.

       Extended data:

       Signs of estrus in cats:

       Through observing the behavior, we can find out whether it is in the estrus period. Although the female cat in estrus is not bleeding like the dog, it is obviously different from the usual, so the owner can easily find out. First, fidgety, no appetite. In the master’s feet to rub to rub, but also made the male cat upset call, in the room a small amount of urination.

       While walking, he rubbed his buttocks on the floor. He squatted and sat with his tail up. He bowed his waist and made a low voice. He put on a posture of being a man. Male cats, on the other hand, are oestrus by the smell and call of the oestrus female. The urine stinks more than usual, barks restlessly, and rushes out. In the cat world, it must be the female cat who chooses the male cat.

       If the male cat that he doesn’t like comes up, the female cat will make an angry cry and lie down on the ground to make it unable to succeed. Immature male cats will not pay attention to them even if they are close to them. If you don’t want to make the cat pregnant, sterilize it as soon as possible. The period from winter to early summer is the estrus period of the cat.

       5-10 days each time. If not, oestrus again after 2 or 3 weeks. If it is not allowed for a long time, hormonal imbalance will shorten the interval between estrus, and it will continue to oestrus. So if you don’t want to breed a cat, you should sterilize it as soon as possible.

       The cat is usually in 6-8 months of estrus, estrus can be sexual intercourse, and then give birth to kittens BB.

       But if you don’t know how big it is, and you want to know when it’s in heat, it’s very simple. One day, you find your cat girl barking late at night. The sound is very different from usual. When you see you, you will come to your feet, roll around on the ground, lie on the ground and raise the PP at you. At this time, you just need to raise its tail and put your finger on the root of its tail bar If you touch it, the whole body trembles, then it is estrus! At this point, you can choose to have it with another cat, or to have it sterilized.

       When a cat is about two months old, it is almost ready to give birth to kittens. As the saying goes, “three cats and four dogs” means that cats are generally born three months old and dogs are generally four months pregnant. However, our cats are generally born in more than two months.

       This is the statistics of theoretical data. It is the basic situation. There will be some differences between different species of cats, cats living in different regions, and even cats of different individuals. It is only for reference.

       The female cat has reached sexual maturity at 6 months old, while the male cat does not mature until 10 months old. The estrus cycle of female cat “spring call” is 2 weeks, 2-4 days each time. ***In the beginning, the female cat may be unkind to the male cat. As a kind of pursuit ceremony, the female cat will refuse the male cat’s first courtship. The female cat rolls on the ground to attract the male’s attention, indicating that she is ready for the fight. ***The process must be repeated several times in 2-3 days to ensure that the female cat is pregnant.

       ***After success, the female cat will not enter the estrus period again, and the earliest sign of pregnancy appears – – the hair around * * turns red and the hair around * * is slightly backward. At 3 to 4 weeks of pregnancy, it can be confirmed by gently touching the abdomen. A healthy pregnant cat does not need any special care in addition to feeding more nutritious and balanced food. Its appetite will increase and its weight will gradually increase.

       The gestation period is about 65 days, or about 9 weeks, from the date of * *. In the last three weeks before birth, the fetus grows rapidly. Kittens born earlier than 58 days usually do not survive and those born after 70 days are larger than normal. The number of kittens in a litter varies from 2 to 6. Special attention should be paid to the last week of a cat’s pregnancy, to make sure it is used to the “delivery room” for it, and not to let it go out or hide itself. Signs of impending delivery include refusal to eat or vomiting.

       Most cats don’t need any help in childbirth, try not to disturb the cat in production, but pay close attention to its condition. A few hours before delivery, the thermometer can measure that the cat’s temperature will drop by one degree. Some major medical supplies can be prepared in case of emergency. Most kittens are born at night, and normally the first is born within 15 to 30 minutes. The kittens born one after another are in danger of being eaten by the female. During and after the production process, the female cat can be given some food and water.

       New born cats are totally dependent on their mothers. For inexperienced females, attention should be paid to keeping kittens warm. The female cat needs to eat at least three meals a day, and the amount is more than usual. If the kitten is restless and incessantly yelling, it may be that the mother’s milk is not enough, and should be checked by a veterinarian. Should not catch kittens to play, there is no need to disturb the mother cat and her kittens.

       In addition to taking care of her children, a newly born female cat can also support 1-2 “orphans”. She will not notice that she has extra mouths. If there is a new female cat, then two females can raise the kitten together. It is feasible to feed “orphan” cats artificially. Start to feed the cat milk substitute every 2 hours. Pay attention to keep it clean and don’t let it catch cold.

       Newborn kittens can’t open their eyes and turn their ears backward. They can’t see or hear. They can’t open their eyes until they are 7 days old. The 3-week-old kittens are free to walk around, so you can give them some solid food. 4-week-old kittens should be trained to use bedpan once they start eating solid food. Put the bedpan in a quiet place and put the kitten on the bedpan after each feeding. Kittens 8-9 weeks old should be vaccinated.

       Cats are in estrus. When it comes to oestrus, there is no need for the owner to worry about it. The female cat will send out a smell to attract the male cat. The male cat will also run away from home to look for the female cat, or squat on the wall of the yard with the female cat for one night, commonly known as “calling for spring”. Then, after a while, the female cat will have a big belly and will give birth to a kitten in one or two months. Please feed more delicious food during this period.

       This is the statistics of theoretical data. It is the basic situation. There will be some differences between different breeds of cats, cats living in different areas, and even cats of different individuals, for reference.

       When the male cat grows to 7 months old, the individual matures. ***It has the ability to breed offspring. When the female cats were about 6 months old, they showed estrus. In estrus, the ovaries of female cats can mature more than one at a time. The mature ones can only be excreted after passing through the same male. The average sexual cycle of female cats is 22 days from the first sexual maturity to the next. A sexual cycle, including estrus and interestrus. In addition to periodic estrus, there are estrus after birth, estrus after weaning and oestrus again after the death of postnatal kittens. It is difficult to conceive after weaning. Only the postnatal kittens die of oestrus and become pregnant.

       When the cat is mature, it can reproduce all year round. The best mating age was 12 months for male cats and 10-12 months for females. If the development is normal and the physique is strong, it can be about two months ahead of time. It is better for female cats to give birth to two children a year. Most cats in the North give birth to one child a year, with the largest number of 5-6 cubs per litter.

       Both male and female cats enter estrus at the age of 6 and 7 months. At this time, although the cat has reproductive capacity, its body has not yet matured, and its bones, muscles and viscera are still growing and developing. Therefore, it is absolutely forbidden to mate at this time. If mated at the right time, it is harmful to the health of both male and female cats and their offspring. It will not only affect the growth and development of male and female cats, but also cause their offspring to grow slowly, be small and have many diseases. The excellent characteristics of this breed may be degraded. Because cats can live up to 15-17 years, which is equivalent to 90 years of human in physiology, but the breeding period is 7-8 years. After that, both male and female cats’ physiological function declined obviously. Female cats even did not oestrus, and male cats lost mating ability. Controlling the number of female cats giving birth can increase the service life of female cats. The female cat can estrus all year round. The gestation period is 63 days and the lactation period is 60 days. It is better for female cats to give birth in spring and autumn. It is better to give birth to two litters a year. In this way, the health of female cats and the quality of kittens can be guaranteed.

       The life span of mice was 1 to 3 years.

       Mother house mouse: the concept of growing for 40 days.

       Mother house mouse: mature growth and 3 months, 21 days pregnant. For the first child 56, add one per litter until a child reaches 15 to 16, reduce one tire per tire, and stop breeding until one is born 5 to 6. Mouse a year pregnant 8 tires, as the saying goes: a man and a woman, 350 a year.

       Mice: mice, mature early, strong fecundity, life span of 1 to 3 years. The newborn is hairless, flesh red, with his eyes open and ears glued to his skin. Zhou crawling, eyes open at the beginning of 12 days.

       Mice, cats and dogs belong to mammals. Mice are pests in people’s eyes, so they are often hunted. Mice can bear 6-7 babies per child and reproduce 4-5 times a year. They belong to animals with high birth rate and high reproduction rate. However, rats have no protection ability for their offspring and cannot feed their offspring. Therefore, their survival rate is very low. However, cats and dogs are beneficial to human beings and are helped by people Even though they have fewer children in one birth and a low birth rate, they have the ability to protect their offspring, so their survival rate is high.

       1£º Mice, it can be pregnant three to eight births a year, each fetus can produce four to eight mice, the largest one can give birth to 14. According to this calculation, a female mouse should have at least 12 mice per year, and the maximum number can be 64. If there are ten females in a family, according to the median value of production, 380 fetuses will be born in a year. If the survival rate is 80% (which is a conservative number), the family will add 304 mice in a year

       2£º Cats, cats can reproduce three births a year, at least three per fetus, and when more than seven or eight. It is conservatively estimated that a female cat will have 100 children in her life. When the cat’s 100th daughter was born, her first eldest daughter gave birth to at least 90 grandchildren. If the first child had three daughters, it would be 270 grandchildren. And these grandchildren can produce thousands of great grandchildren

       3£º Dogs, in general, will have their first estrus at 6 to 10 months, and individual breeds (such as large dogs and giant dogs) will be delayed. It’s not suitable for the first time because the dog’s body has not yet passed its growth period and is still under age. Generally speaking, from the first estrus, the female dog can be estrus every six months, that is, twice a year.
