8. Cat's characteristics and living habits: cats are agile and good at jumping. Eat fish, rats, etc. The reason why cats like to eat fish and mice is that cats are nocturnal animals. In order to see things at night, they need a lot of taurine. Mice and fish contain taurine in their bodies. Therefore, cats eat it not only because they like fish and mice, but also because of their own needs. As a natural enemy of rodents, cats can effectively rece the damage of rodents to crops, such as seedlings. The shape of "Miao" of cats shows the essence of agricultural life in ancient China. The cat can walk on the high wall as if nothing had happened and jump lightly. It can't help but be convinced by its sense of balance. This is mainly e to the cat's outstanding reaction nerve and sense of balance. It only needs to slightly change the position and height of the tail to achieve the balance of the body, and then use the strong muscles and strong joints of the hind foot to jump quickly. Even if it falls in the high altitude, it can also change its body posture in the air and land lightly and accurately. Good at climbing, but not good at falling from the top. Even when a cat falls or jumps from a height, it uses its tail to adjust its balance so that its padded limbs land on the ground. Pay attention not to break the cat's tail, it will affect its balance ability, it will also easily make the cat diarrhea, shorten the life of the cat. As for the sleeping state, cats spend 14-15 hours in sleep in a day, and some cats sleep more than 20 hours, so cats are called "lazy cats". However, if you carefully observe the way a cat sleeps, you will find that as long as there is a little noise, the cat's ears will move. If someone comes near, the cat will suddenly wake up. Originally, cats are hunting animals. In order to keenly feel all the movements of the outside world, they don't sleep very hard, so they shouldn't be called "lazy", because cats only have 4-5 hours of real sleep, and most of the time they should be considered as "sleeping" or "keeping their eyes closed". But since childhood, cats used to stay with humans sleep more dead and sleep longer. Wayward cat seems to be a bit wayward, go their own way. Originally, cats like to act alone, unlike dogs, which obey their owners' orders and act collectively. Therefore, it does not regard the master as a monarch, but obeys. Sometimes, it doesn't hear what you call it. Cats and their owners are not a master-slave relationship. It's better to regard them as equal friends. It is this kind of relationship that makes it unique. On the other hand, cats regard their owners as their parents and act like children. When they feel lonely, they will climb up their owners' knees or jump to the open newspaper to sit, showing their delicate posture. Cleanliness cats often clean their hair. Kittens in many times, love to lick the body, self-cleaning. After meals, the cat will wipe its beard with its forepaws and lick its hair with its tongue after being hugged. It's the cat's instinct to get rid of its own smell to avoid predators. There are many rough protuberances on a cat's tongue, which is the most suitable tool to remove dirt. After the owner caresses the cat, the cat licks the place where it is caressed: the cat is remembering the smell of people, because it is worried that it will not find the owner after it is separated from the owner. Many people mistakenly think it's a cat that thinks it's dirty. When the emotional cat is happy, its tail will stand up or make a purr sound. When a cat is angry, it wags its tail hard. If you make it angry, it may pounce on you. Many people have been complaining that their cat always catches and bites people. The scars on their bodies do imply the tears of their owners. But it's not all the cat's fault. The owner also has a certain responsibility. Cats are not human beings. They are lovely, but they can't understand human psychology after all, and human beings can't explore what they are thinking. If we get along with each other for a certain period of time, we can understand each other's many thoughts. First of all, the evolution of cats has been moving towards the direction of super hunters. All their organs are designed to catch up with their prey and kill them quickly. Although they have been pets for thousands of years, these structures have not disappeared. For example, the intensity of fighting between cats can not be used on humans, so let the cats know that they will hurt you if they do so. Generally, cats learn skills by catching up with each other in the process of growing up. After this stage, they will also understand what strength will not hurt their partners, but this strength is not suitable for human beings. Therefore, in the process of cat growing up, when the cat grasps you and bites you, it is necessary to stop it, such as yelling loudly and smacking it with a little force, In this way, you will graally understand what strength to "attack" you with. You put your hand in the dog's mouth, the dog will not force, has been open mouth or gently bite, the cat is completely OK, if it takes the paw to you, most of the time will put away the tip of the paw. It just needs training and guidance. After all, cats are much later as partners of human beings. Our generation and future generations are trying to make domestic cats pets.
