Cats and dogs are the two animals we know most about, but their habits are very different, especially when dogs act very quietly during an inclement period, while cats scream torn apart during an incendiary period, and they sound very perceived and scared。
What the hell is going on here
Cat and dog strategy
In fact, the dog has a certain amount of irritation during an inclement period, for example, in the home, and even the desire to go out and play。
The female has a menstrual period of 1-2 weeks each, which occurs twice a year, 7-10 days after the first onset. Unlike humans, the emergence of human menstruation is the disempowerment of the uterus and the absence of pregnancy. However, dog discharges are slime permeable from utero skin cells, which means that they can mate at this time and are susceptible to pregnancy。
When dogs come to menstruation, their scent is extremely tempting for opposite sex, and when they smell the opposite sex, they come to date it and prepare for the baby。
Cats do not have the same strategy as dogs, and cats do not attract opposite sex by smell, but by shouting. In heat, the female goes out to the field at night and screams to attract the opposite sex around, which seems to us to be a terrible sound, like a horror play, but it sounds like a male cat, and it's called "wedding concerts," and it comes on a date。
Cats are cats. Cats have one thing in common: the male bites the female neck at mating and the female screams at mating。
This is mainly due to a characteristic of cat animals, which do not ovulate before mating, but require a certain amount of stimulus to ovulate。
The male genital cortexes have the same components as human nails, so they are of a certain degree of hardness, strongly irritating the female during mating, and the female sexiest knows pain before ovulation。
The other advantage of a backstabbing is that the sperm that was left behind in the female body can be taken out of the body, thereby increasing the competitiveness of the female sperm and making it easier for the female to bear her children。
This strategy is good, but it costs the female, because the repulsive structure has a certain hardness and the genital organs are so delicate that she can feel pain during mating, and that is why the male bites the female's back neck when he mates, fearing that she will escape. Cats will do the same, and when the mating is complete, the females will go after the cats for pain, which is why we will hear two cats fighting after a while。
Fortunately, cat mating does not take long, with lions, for example, having only 5-20 seconds at a time, but in order to increase the fertility rate of lions, lions mate 20 to 100 times a day. As a result, lions are often followed by lions during periods of conflict。
Dog reproductive strategy
In addition to the different manifestations of the onset, the reproductive strategies of both are different。
Dogs use back-to-back mating, which cannot be stopped during the mating process, and forced intervention can cause injury to both. This position is maintained because the sponge at the end of the male genitalia expands during mating and reverses the cone structure, making male organ cards. In the female body, it takes about 20-30 minutes for the whole process to be separated only after no more ingestion。
Cats mate for a relatively short period of time, for a few seconds, and can end at any time, and do not get hurt even if they interfere。
These two types of mating are excellent and poor, and dogs are mating for a long time, during which they are able to pass as many of their genetic cells as possible to the females, and can take control of the dog's mating time, and because other heterosexuals cannot separate them, the dog's partner is smaller。
The disadvantage, however, is that the length of the mating is too long for them to be attacked by a natural enemy, at a time when the dogs have little capacity to defend themselves and are unable to break up by force, and when they encounter a beast, it must be a rare occurrence。
Cat mating strategies have the advantage of being flexible and ending in a short period of time, but the disadvantage is that multiple matings are required to be successful because of the short time available, the low amount of genetic material injected into the female cat and the difficulty of pregnancy. This is why lions mate 20 to 40 times a day。
Summary
For animals to live on earth, it is necessary to adapt to the earth's environment, whether survival or reproduction strategies, to its ecological position, otherwise it will be naturally extinct。
Cats and dogs have different reproductive strategies, but they are perfectly adapted to the environment, and they are preserved。
