What’s a cat changed – what kind of animal is a cat

       The pupil of cat’s eyeball is very big, and the contractile ability of pupil’s sphincter is also very strong. Cats in different light, a good adjustment with the pupil. In the morning under the moderate intensity of sunlight, the pupil will form a jujube like appearance. In the strong sunlight at noon, its pupil can shrink very small, like a line. In the dark at night, the pupils can open as round as the full moon. Because the cat’s pupil has good contraction ability, it is very sensitive to light. So the cat’s eyes change three times a day in order to see things clearly when the light is too strong or too weak.

       The pupil of a cat contracts with the intensity of light. During the day, the light is strong, it will hurt the eyes, so the pupil will shrink. In the evening, the cat to go out for food, in order to be able to see at night, will enlarge the pupil, let more light into the eyes. Not only do cats contract their pupils, but many animals do

       To start from the role of the pupil, it is located in front of the lens, is to control the intensity of light into the lens, with the external light intensity and change in size. At night, when the pupil of a cat becomes larger, it receives as much light as possible. However, because of the convergence of lens and ciliary body, that is, convex lens, the light converges in a small range. It is precisely because the pupil is large and the photosensitive cells of human beings in the dark are columnar cells, and the sensitivity is enhanced, it can be seen that the changes are observed.

       As everyone knows, cats catch mice. The night is a time when rats are rampant and cats are busiest. The meat pad under the four feet of a cat is soft and elastic. It is very light when walking. Even if it jumps up and down and runs around, it makes only a slight sound.

       The cat has a pair of big eyes that can change shape several times a day. Sometimes it is big and round, sometimes it is a thin line, sometimes it is like a jujube stone.

       The structure of cat’s eyeball is special. When the light passes through the retina and reaches the iris at the back of the eyeball, it will be reflected to the retina again for imaging. This is why cats can hunt with the help of low light level light at night. The light reflected back from the iris still passes through the retina, which is why the cat’s eyes glow in low light.

       Cats can be said to be many people like animals, cute pet cats can always get people’s love. So when was the cat raised by the ancients?

       In the history of China, there are records about keeping cats for a long time. Cats have the nature of catching mice. Therefore, in the early stage of human society, cats can reduce the harm of rats, which is conducive to agricultural production. At this time, cats are regarded as one of the “eight gods”. Later into the agricultural society, people began to deliberately domesticate cats. On the whole, the main reason why people kept cats during this period was that they caught mice. In the early records, most of them are “civet”. Modern scholars think that civet and cat are a kind of creature.

       In the Warring States period, the record of cat catching mice appeared. In the Han Dynasty, there were more records about beavers, but they still focused on the function of catching rats in this period. In Shuoyuan of the Western Han Dynasty, Liu Xiang also talked about catching rats with beavers. There is a general meaning that the beavers can be bought in the market for only 100 yuan, and they have good ability of catching rats. It can be seen that many people had raised beavers to catch rats at that time.

       Cats have always been used as tools of human production, until the Tang and Song Dynasties, people domesticated cats gradually weakened their function of catching mice, and cats gradually became “pets” accompanying people. It should be noted that in the Tang and Song Dynasties, the appellation of cat and cat coexisted. At that time, cat was also called “Li Nu”. Li Nu was a kind of pet name for cat, which showed that cat was understandable and driven by people. It can be seen that cats are domesticated beavers.

       As pets, cats come into people’s daily life. More and more cats appear in poetry, calligraphy and painting, and even some people specially photograph cats. It can be seen that the partnership between cats and human beings has a long history. Modern “cat slave” refers to people who like cats, which is similar to the ancient “cinu”.

       It seems that the relationship between the landlord and your cat is very deep! This also shows that the fate between you is also very deep, under normal circumstances, you will still have a deep fate in this life or the afterlife, but it is not clear what kind of image she appears. Because most cats eat more meat and fish, they may fall down after death, and may be reborn because of their good deeds in previous lives. So please take good care of the other animals around you, because it’s hard to say that it’s not the birth of the poor cat, because only the sentient beings who are close to you can come to you.

       In addition, to be on the safe side, it is suggested that you read more Mahayana sutras such as the Vajra Sutra or the Bodhisattva Sutra of Mahayana to return to her (that is, after reading, meditate on the hope that this merit cat can get it and thus get a good place to go). I believe it will play an important role in her. Maybe she will be your child (not joking), or she will become a God because of your kindness.

       

       Cats are quick and good at jumping. Eat fish, mice, rabbits, etc. The reason why cats like to eat fish and mice is that cats are nocturnal animals. In order to be able to see things at night, they need a lot of taurine, and the body of rats and fish contains taurine. Therefore, cats eat not only because they like fish and mice, but also because of their own needs.

       The cat can walk on the high wall as if nothing happened, light jump, can not help but be satisfied with its sense of balance. This is mainly due to the cat’s outstanding response nerves and sense of balance. It only needs to slightly change the position and height of its tail to achieve body balance, and then use the strong muscles and strong joints of its hind feet to jump quickly. Even if it falls in the air, it can change its posture in the air and land lightly and accurately. Good at climbing, but not good at falling from the top. Even when falling or jumping from a height, the cat uses its tail to adjust its balance so that its padded limbs land on the ground. Pay attention not to pull off the cat’s tail, which will affect its balance ability, and also easy to cause cat diarrhea, shorten the cat’s life span.

       From the Southern Dynasties to the early Sui Dynasty, domestic cats were introduced into China through the exchanges between the two countries. They took root and sprouted here and became a favorite pet of Chinese people.

       In the classics of pre Qin Dynasty, the book of songs truly mentions “cat”: “Shida Ya Han Yi”: there are bears and bottoms, cats and tigers. Mao’s just saying: cats are like tigers with shallow hair. “

       From the northern and Southern Dynasties to the early Sui Dynasty, the cat was introduced into China from Arabia. Because of its nature of catching mice, the Chinese people realized and fell in love with this small and intelligent animal. It became a God in the eyes of the ancients to eliminate mice and protect granaries.

       According to the book of songs, in the Shang and Zhou dynasties, there was a kind of sacrificial activity to worship eight kinds of deities, called “Bala”, in which cats were worshipped.

       The reason is very simple. It is said in the book of rites that “the ancient gentleman must report it, and the cat will eat the vole for him”.

       After that, the cat that catches mice was respected by people and introduced into human settlements. After a long period of time, the cat on the altar changed into the cat in the secular society, the wild civet cat became the domestic civet slave (the pet name of cat in the ancients), and the meritorious official of rat catching gradually became the pet of people’s family. From then on, there was the cultural history of cat.

       Domestication of domestic cats

       As a docile, intelligent and lively animal, cat has a long history as a family pet, especially in European and American countries.

       At the beginning of the 20th century, a zoologist in the United States first invented cat tree, a product designed to treat the growing depression of domestic cats.

       Its scattered space combination enables the domestic pet cat to have free play space, stimulates the cat’s nature, and the natural hemp rope on the product lets the cat feel the natural breath, and can maintain the physiological habit of grinding claws without destroying the furniture.

       1. Cat, belonging to the cat family, is a more extensive family pet in the world. The ancestors of domestic cats are supposed to be desert cats originated in ancient Egypt, Persian cats in Persia, which have been domesticated by humans for 3500 years (but not completely domesticated like dogs).

       2. In 2009, the journal scientific man once reported that through the comparative analysis of nearly 1000 DNA samples, it was determined that the ancestors of domestic cats today were from the same lineage, all of which were Middle Eastern wildcats. There are many evidences and materials about the history of domestication of cats by human beings. About 4500 years ago, a large number of wild cats were domesticated in ancient Egypt.

       3. The earliest record of domestic cats in China appeared in the Western Han Dynasty. Before that, there was no cat in all kinds of written records, murals, totems and other images. There was once a conjecture in the academic circles that domestic cats entered China through trade with foreign countries in the Western Han Dynasty or a little earlier, which was generally believed to have been brought in by Persian merchants.

       4. However, recently, according to Taiwan media reports, Hu Yaowu, a professor at the Chinese Academy of Sciences, said that as early as 5300 years ago, the residents of Quanhu village in Shaanxi Province would use cats to control rodents. The evidence is that eight bones of two cats have been found in Quanhu village. Using radiocarbon dating, the researchers dated the bones to a 200 year period about 5300 years ago, more than 3000 years earlier than previously thought domestic cats appeared in China.

       5. The size of the bones is about the size of a modern European domestic cat, but smaller than that of a European wildcat, the researchers report. At the same time, the isotopic analysis of bone showed that the ancestors, pigs, mice and cats in Quanhu village ate a lot of millet based food; one of the two cats ate less meat than other cats and ate more millet based food, suggesting that the cat might have eaten human leftovers or be fed by humans.

       6. There is a general assumption in academic circles about the domestication process of cats. It is generally assumed that the food of human habitation attracts rats to steal, and cats are attracted by mice. When people find that cats can catch mice and control rat infestation, they start to try to let cats stay, and finally complete the domestication. Cats gradually become a member of human beings living under the same roof.

       Extended data

       There is no need to say that humans love cats. The popular “cat sucking culture” is the best evidence. It can be said that among all the species we domesticate, cats have a very special emotional status in people’s hearts. However, the relationship between domestic cats and human beings has undergone many complex changes: from a highly functional prevention and treatment of mice to a gradual change to family companionship. Today, domestic cat has become an ecological threat in the eyes of many scholars.

       We often hear from various sources that cats have nine lives. There are many stories and legends around the world that cats have nine lives. In fact, the reputation of cats with nine lives is attributed to their ability to jump and land.

       Although the cat can adjust to minimize damage. But it doesn’t mean you won’t fall to death. If the falling height is too low, the cat has no time to adjust; if it is too high, the impact force is too large, and the cat will still be injured. So sometimes cats die when they jump off the 7th floor, but it’s OK to fall from the 16th floor.

       The earliest record and literature of cats in the world is the book of songs Daya Hanyi in the Western Zhou Dynasty, which says, “there are bears, there are cats and tigers. But the poem juxtaposes cats with bears and tigers, which does not seem to refer to domestic cats.

       In the Warring States period, “Chuang Tzu – autumn water” mentions that “when a horse gallops for thousands of miles in a day, it is better to catch rats than to catch a beaver.”.

       In ancient China, Cibi mostly refers to wild cats. However, if we compare cats with good horses, they probably refer to domestic cats. It was not until the early Western Han Dynasty that it was clearly pointed out in the book of Rites – suburban special animals that “the ancient gentleman must report it, welcome the cat and eat the vole for him.”. It has been affirmed that cats are domestic animals and domesticated.

       Domesticated cats appeared in Egypt about 3000 years ago. They were first domesticated by residents of the upper Nile River to help hunt small animals. Since then, with the development of agriculture in Egypt, food was left over and rat infestation broke out. The matter of keeping cats and killing rats became increasingly prominent. Even laws and regulations were formulated to protect cats. Those who killed cats would be sentenced to death. The cats raised by nobles will be coated with sesame oil after death to achieve the purpose of antisepsis and buried in sarcophagus.

       European domestic cats originated from F. silvestris in Africa, and Asian cats are generally believed to have originated from desert cats in India.

       China is the origin of cihuamao cat. It belongs to the natural cat, because it is a breed that has been eliminated naturally for thousands of years.
