Felines are omnipotent, they are nature's top predators, most members can stand at the top of the food chain, from the overlord African lions in the African savannah, to the king tigers in the jungles, and of course, the cute powder-sucking cats around humans.
They are the only felines that have evolved to become human pets, cats and dogs are the most common human pets, and the number of pet cats and dogs in China has been counted by relevant institutions before nearly 100 million, of which pet cats rank second, with more than 40 million.
People who have raised them should be very clear that there is a clear difference between cats and dogs, dogs are more loyal and docile, while cats are relatively cold, even if they do not give a good face to their owners sometimes, so pet cats are often jokingly called "cat masters". Dog scientists analyze their domestication process and believe that cats can become human pets should be a two-way selection process, it is they who actively want to become human pets, we are just a passive acceptance party.

Cats should be the closest cats to humans, because their presence can also allow us to better understand other cats. Cats are agile and capable of hunting, and their two favorite small animals are mice and fish. Biologically taxonomized as a member of the cat family - cat subfamily - cat genus, divided into night cats and domestic cats, it is distributed worldwide.
Cats like to be nocturnal because their large eyes are good enough at night, and during the day at home sleepy eyes are always resting. Their personality is slightly high and cold, and sometimes the owner calls it, it does not hear it. And sometimes it will take the initiative to lie next to us and purr and sleep, and it is this unique personality that tightly grasps our hearts.
Australia should be the only region in the world where there is no wild cat species, but because of this, domestic cats have been able to flood this unique part of Australia. Australia is truly a special place, with its own unique species, and often so weak in the face of alien invasions. Typical examples such as the European hare flood in Australia, the maximum number can reach nearly 10 billion.
We never thought that the excessive number of cats can cause serious effects, and what bad thoughts can cats have? According to statistics, hundreds of millions of birds are eaten by cats every year in Australia, and many bird species are sharply reduced in number and are in danger of extinction. The life of cats is relatively long, especially the living environment conditions of domestic cats are relatively good, generally can live for about 10-15 years.

Cat breeding season does not have a fixed period, they belong to the seasonal multiple estrus species, for male cats, after maturity in estrus it will appear "enuresis" behavior, it will arch the body to lift the tail, and finally spray urine on the upright object, of course, the purpose is to attract the arrival of the female cat, in this period it is not used to staying at home, but often run out.
The estrus of the female cat is even more special, they will make a long call, it sounds a bit miserable, in the countryside generally called this phenomenon "called the straw". This call can attract male cats in estrus, while female cats in estrus at home will be spoiled, their forelimbs lying on the ground, their butts cocked in mid-air, and their hind legs look cute like bicycles.
Cats in this period are a bit irritable and reluctant to eat, especially at night when they have to go out, the whole time cycle can last about 20 days, after which the cat will return to normal.
< h1 class="pgc-h-arrow-right" why is mating so painful > cats? </h1>
In fact, like most felines, cats can lay eggs during estrus, but spawning must be stimulated, because cats are stimulating spawners. Therefore, their reproductive organs are more unique, the cat's little Tintin is like a small wolf's tooth stick, and the female cat is extremely harmful during the mating process.
In fact, in the process of evolution, such a peculiar organ as a male cat also has a certain role, so that in addition to stimulating the female cat to ovulate, it can also remove the reproductive cells of other individuals and ensure that their offspring reproduce as much as possible. This is a common feature formed by many species in evolution, all of which are self-interested, of course, this is also the essence of biological evolution.
In fact, it can be seen that the female cat rolls over and attacks the male cat after mating is the reason. Because this mating process is very painful for the female cat, if the male cat does not run in time after mating, it will be attacked by the female cat. But survival and reproduction are the most essential pursuits of all species, so this process is inevitable, and the same is true of the female cat, which expects to give birth to her own offspring, but after suffering it will take revenge on the male cat, and if it runs slowly, it will be attacked. While the female cat rolls after mating, scientists believe it may be beneficial to produce more offspring.

In fact, most cats are like this, they use this way to eradicate dissidents, but also can perform stimulating ovulation, which is positive for the development and evolution of the population.
