Some information about cats (common sense)?

Cats have many unique functions, mainly in the following aspects:

First of all, cats have very good eyesight. In fact, vision can be said to be the most powerful sensory system of cats. After all, their pupils are so big. If our pupil ratio is the same as that of a cat, then we can have a pair of shining eyes with a diameter of 20 cm. Although cats can instantly see and distinguish objects in extreme darkness, most people still doubt their eyesight and even think they are color blind.

Second, cats are very accurate in judgment. Beard, as a cat's navigation in the absence of light, is always in an extremely sensitive state, and it will feed back the surrounding environment to the cat. The clever cooperation between beard and olfactory system can make cats keep correct judgment in complex environment or when danger comes.

Third, jump far. Cats' hind legs are longer and stronger than their front legs, which is why they can jump so far.

Fourth, cats like sleeping very much. In fact, sleeping is a gift of cats, because cats' snooze ability is unparalleled, so powerful that no animal can compete with cats' snooze ability except hibernating animals. People spend one third of their time sleeping every day, while cats spend three quarters. In fact, in the remaining quarter of the time, cats only do two things, that is, eat and tease their owners.

Fifth, cats have very good hearing. According to scientific research, the hearing range of human beings can reach up to 23000Hz, while that of cats can reach up to 85000Hz, which is the dynamic sound made by mice. Nowadays, cats listen attentively to the opening of cat food cans or biscuit boxes, and their technology is close to the pace of the times. Many people should not know that a cat's ears have 32 muscles, and the two ears do not affect each other and can rotate at will. In fact, the human ear has only three muscles. Compared with the ears of cats, people's ears are much worse and their hearing is much weaker.

All in all, these are the characteristics of cats.
