A detailed history of cats

Domestic cats, also known as cats, are small cats. The famous Latin literature is Felis silvestris catus or Felis silvestris domesticus, but sometimes it is also classified as Felis domesticus or Felis catus in species. Felis catus is a common species name at present. Cats have been domesticated by humans for 3500 years (but not completely domesticated like dogs). The ancient Egyptians kept cats to catch mice and other rodents and prevent them from eating their own food. Nowadays, cats have become a very widespread pet in families all over the world. In English, male cats are called "Tom" (in cartoon purebred cats, owners will let cats breed what they think is "perfect" (see selective breeding), but because purebred cats are mostly inbreeding, their health is generally worse than that of mixed-race cats. Only 1% cats are pure blood, and the other 99% cats are mixed-race, commonly known as long-haired cats and short-haired cats. Non-thoroughbred cats are called "Moggy" in Britain; They are called "alley-cat" in America, even if they are not wild cats or stray cats (alley means narrow alley in America); It is called "mix" in Taiwan Province Province. Dead cats weigh between 2.5 and 7 kilograms (5.5 to 16 pounds), and a few will exceed 10 kilograms (22 pounds). At present, it is known that overfeeding will reach 23 kg (50 kg), so this unhealthy behavior for cats must be avoided. Cats can live 15 to 20 years under feeding conditions, and the longest known cat lives for 36 years. Domestic cats can live longer if they are not allowed to go out, or if they are ovariectomized or castrated (to avoid attacks and accidents). Wild cats in modern cities usually only live for two years, or even less. Cats have fat pads under their toes, so they walk quietly. Cats, like grassland dwellers, can adapt to the climate with large temperature difference, but the time is not long. They can adapt to dense fog, snowfall, rainfall and other weather, but compared with other species, Norwegian forest cats and Maine raccoons are more adaptable to these environments. When the environment is humid, cats try to keep their body temperature at 39 degrees Celsius (102 degrees Fahrenheit). Most cats don't like to stay in the water, the only exception is the Turkish cat. The ancestors of wild cats and domestic cats are thought to come from grasslands, and their daily behaviors are very similar. Cats like to rest in a warm and sunny environment. The cat's excrement is dry, and they bury it in the sand. Cats can also stay still for a long time, especially when observing prey or preparing for an attack. The ancestors of wild cats in North Africa may also be related to domestic cats. Domestic cats must have a sandbox filled with cat litter, similar to human toilets. In fact, it is best to have a sandbox for keeping cats indoors or outdoors, but some domestic cats can directly use human toilets-of course, toilets need to be modified-which is also the result of long-term adaptation to human life. You can also prepare a cat scratch board for your cat. Predation is the same size. Domestic cats are the top carnivores in the world. They can prey on thousands of animals, while big cats can only prey on less than 100 animals. However, due to the small size of domestic cats, the only threat is probably the infectious diseases (or rare rabies) attached to bites. Historically, it is difficult for local species to adapt to exotic species like cats, so the introduction of cats will pose a great threat to the ecosystem. In some cases, cats are responsible for helping or causing the extinction of local species. Cats, like other big cats, ambush first and then prey quickly; Bite the neck of the prey with a violent impact or with its sharp canine teeth, bite off its spinal cord and trachea, and kill the prey. Cats are considered as ideal carnivores. They have excellent cracked teeth and digestive tract, premolars and molars on both sides of the gums, and can cut meat as efficiently as scissors. When dogs evolved this mechanism, cats have made considerable progress. Unlike other carnivores, cats hardly eat any plants. For example, bears or dogs usually supplement foods such as fruits, roots and honey, but cats specialize in meat. Cats can't adapt to vegetarianism because it is difficult for them to digest and absorb plant components to synthesize essential amino acids. For domestic dogs, some plants are usually mixed with meat when feeding, and even some dogs will become vegetarians completely. In terms of food size, cats eat less and eat more. Cats like to prey on mice and sometimes eat frogs, snakes and so on. Cats also have a nickname: picky eaters. This is because they have sensitive olfactory organs, are quite sensitive to special foods and can resist inappropriate foods. When a cat wrinkles its mouth, lowers its chin and licks food with its tongue, it means it is smelling food. Dogs and horses do the same thing. What does this cat eat? With the changes of the times and the living environment of urbanites, the food for cats is no longer "cat fish for rice". Instead, there are all kinds of prepackaged foods. The formula of these cat foods is tailored to the nutritional needs of cats? It can not only provide the nutrition that cats need, but also has diversified tastes, including pigs, cows, chickens, seafood, liver, sheep and so on. Convenient and hygienic, it is very popular with cat owners. Prepackaged foods is mainly divided into the following three categories: (1) canned food (2) soft and wet food (3) dry food * No matter what kind of cat food your cat eats, the cat owner must provide enough water for the cat to drink. Cats' "Toilet" Cats naturally like to collect their own excrement, so the cat basin is an ideal "convenient" place. As long as the cat owner chooses the right litter and cleans the cat's excrement frequently, it can provide a clean and tidy environment for the cat and the owner. The power of cats-Sleeping cats sleep 16 hours a day on average. Cats sleep in two states: deep sleep and non-deep sleep. 30% of the time is deep sleep, 70% of the time is easy to wake up, and the two States alternate. Cats like to sleep in warm places. They also like people's body temperature. They often lie curled up next to their owners. Cat's Claw Grinding Behavior For cats, claws are the most important weapon, and they are also tools for climbing trees, hunting and dividing pots. Therefore, the behavior of grinding claws can be regarded as the instinct of cats. If the cat is not allowed to grind its claws moderately, the long claws will grow into the meat pad, which is very painful. In addition, the behavior of grinding claws can make cats eliminate tension, stabilize their emotions and maintain their health. Therefore, the cat owner should provide a place suitable for grinding claws, otherwise your beloved furniture may become the object of cat grinding claws. "Cat" animals are divided into "leopard", "cat" and "cheetah" (a few taxonomists suggest that clouded leopard be listed as a separate genus), and there are 25 kinds of cats. 1. "Leopard" includes lion, tiger, leopard, leopard and snow leopard. And the Northeast Tiger, a subspecies of the tiger in Leopard, are the largest cats. 2. "Cats" include domestic cats, leopard cats, Shi Hu, pumas, etc. Pumas, also known as mountain lions, are the largest cats. Although the appearance of "cats" is very different, they are quite similar in anatomy. For example, tigers and lions are very different in appearance, but it is difficult for ordinary people to see the difference without the bones of hair and meat. There is a simple way to distinguish between "leopard" and "cat" in "cat". Leopard cats can make a shocking rough roar, while cat cats can purr or meow because of the different bones in their throats. There is only one kind of "cheetah", which is a specialized cat. It is the sprint champion of all animals, and its instantaneous acceleration is faster than that of Porsche sports cars. In order to increase the grip when running, it became the only cat whose paw did not retract, just like people wearing spikes. About 10,000 years ago, this animal was still common in Asia, Africa, Europe and North America. At the end of the last ice age, due to the rapid climate change, many mammals gradually disappeared, and cheetahs almost survived, which made them genetically close to today. All cats have spots on their fur during evolution. Experts have studied that the spots of their ancestors may be simple black spots like cheetahs, and later they may evolve into spots like leopards or leopards. The tiger stretched the spots into strips. Although lions or cougars have no spots, their young children all have spots left by their ancestors and disappear when they grow up. A. Classification of cats according to their living environment: cats that have been domesticated by human beings, but will not be too dependent on human beings and remain. Wildcat: It is the ancestor of domestic cats, living in desert, mountains and other wild environments. Cats appeared as early as12 million years ago. B. Pure-bred cats bred by breed: refers to cat breeds that have been carefully bred for several years and generations, and their breeding procedures are strictly controlled to avoid breed degradation. The genetic characteristics of this cat are very stable. Kittens and their parents' cats have similar characteristics, and each cat has a pedigree record, including gender, breed, body characteristics and ancestors. Hybrid cat: refers to a breed that is not controlled by human beings and breeds by itself. The genetic characteristics of this cat are very unstable, and the kittens in the same litter often have different coat colors. C. Long-haired cats such as Maine cats, Lagardor cats, Himalayan cats, Persian cats and Somali cats are classified according to the length of their coats. Siamese cats, American shorthair cats, Japanese shorttail cats, Russian blue cats, foreign shorthair cats, Abyssinia cats, Scottish flat-eared cats and other shorthair cats. Basically, cats are not animals that need to live in groups, and they don't need people to take care of them all day. In fact, it can be said that almost all cats pretend to be lonely. There is no leader in their world. Because of their high degree of autonomy, they are naturally unwilling to obey the orders of a third party. Generally speaking, cats are absolutely not allowed to be deprived of their sex, but they are not really so ruthless; Of course, it can feel the kindness of its owner and then repay it with affection and respect. Therefore, for people who love cats, this sometimes indifferent and sometimes almost spoiled temperament is what attracts them. Cats became pets later, probably as early as ancient Egypt; Generally speaking, a stone statue of a cat often stands next to the stone statue of Pharaoh.

There are even mummies of cats, which means that cats have been raised since then. When cats became family pets and became popular, it was around the eighteenth and nineteenth centuries. Therefore, the natural wild instinct has not been completely domesticated. Cats have well-developed sensory organs, are agile and can make a keen response to the surrounding environment, so they have a strong instinct to hunt. Cats have a keen sense of smell like dogs; However, unlike dogs, cats chase prey by smell, but try to find the path of prey first and then ambush it. Motivation is not necessarily because of hunger, sometimes it is a sport or even a game. Therefore, for domestic cats, mice, birds, geckos, cockroaches and so on. , is a common, terrible, moving creature in the home, may be the object they chase or catch prey, or even the gift they bring to their owners for credit. Don't be afraid. Cats are naturally adventurous, so they also have strong curiosity and interest in the world around them. It may be looking for a warm place to doze off, or just want to see what this thing is. What's more, it may be looking for prey to catch, trying to train its hunting skills or becoming the object of the game. Anyway, cats are not boring.

When a cat wrinkles its mouth, lowers its chin and licks food with its tongue, it means it is smelling food. Dogs and horses do the same thing. Although socialization is described as a non-social animal, domestic cats can still flock in the wild, just unlike lions. When each cat has obvious territory (the male cat has the largest territory, and the castrated cat has the smallest), in the so-called neutral zone, the cats' territory is smaller, or they invade each other. Except in the neutral zone, cats holding territory usually take the initiative to resist strange cats, stare and hiss, and if the cats haven't left, the territorial cats will launch fierce attacks. A cat that wants to attack will expand its body, erect its hair, or erect its body into an arch. When attacking, you usually slap your face with your front paws, but there are few serious injuries. If you lose, you will leave in a hurry with only a small scratch. Sexually speaking, male cats often leave some scars on their faces because they are often attacked in their lives. Of course, not only male cats will attack, but also female cats will attack for territory or to defend their children. Castrated cats will also take the initiative to defend their small territory. Male cats have thorns when they erect. During mating, the erect penis will touch the vaginal wall of the female cat. Female cats must rely on this way to stimulate ovulation. So female cats rarely get pregnant at the first mating. Most cats are pregnant for 63 days and kittens are weaned at 6-7 weeks. After 10 to 15 months, their sexual characteristics will mature, the mother cat will give birth to multiple births at one time, and the mother cat's uterus also has four ovaries. Knowing that cats have excellent day and night vision, in bright places, cats will narrow their pupils to a line to reduce the damage to the retina, but it will limit the breadth of vision. There is a blue-green fluorescent film (called tapetum) on the back of the cat's retina, which can improve the vision in the dark. Under the flash, the cat's eye can take on various colors. Like most carnivores, their eyes look straight ahead, which gives them a wide field of vision. Cats have poor ability to recognize three primary colors. If cats have only dim light here, they will use beards to improve their mobility and perception. In the case of low visibility, the beard can feel very weak wind to identify obstacles. A cat has three eyelids. When the cat's eyelids are opened, the dazzling eyelids will slightly cover the eyes from the side. If the cat is sick or asleep and laughs, its eyelids will retract a part. If the cat shows its third eyelid for a long time, it means that it is going to see a vet. Almost all cats usually prick up their ears. Unlike dogs, cats with ear injuries are very rare. The Scottish folding cat is an example of genetic mutation. When angry or frightened, the cat's ears droop, accompanied by a roar. When listening to something, the cat will turn its ears, so that the cat's ears can hear sounds from many aspects. There are quite a few kinds of cats, each with its own unique characteristics. Under the selective mating of human beings, cats are divided into long-haired cats and short-haired cats according to their fur types. Tiger-striped cats have many colors and patterns, but this is because of different breeds. They are all the same species, and the most common is the tiger-striped cat.
