Some information about cats (common knowledge)?

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

First, cats have very good eyesight. In fact, vision is arguably a cat's most powerful sensory system, after all, their pupils are so large. If our pupil ratio were the same as that of a cat, we would have a pair of shining eyes 20 centimeters in diameter. Although cats can see and identify objects instantly in extreme darkness, most people still doubt their vision and even think they are color blind.

The second point is that cats have very accurate judgment. Whiskers are always in an extremely sensitive state as a cat's navigation in the absence of light, and they will feedback the surrounding environment to the cat. The clever cooperation of whiskers and olfactory system allows cats to maintain correct judgment in complex environments or when danger approaches.

The third point is to jump far. Cats' hind legs are longer and more powerful than their front legs, which is why they can jump so far.

The fourth point is that cats like to sleep very much. In fact, sleeping can be regarded as a kind of cat's talent, because the cat's ability to snooze is unparalleled and so powerful that except for hibernating animals, no animal can compete with a cat's ability to snooze. Humans spend one-third of their day sleeping, cats three-quarters. In fact, in the remaining quarter of the time, the cat only does two things, namely eating and teasing its owner.

The fifth point is that cats have very good hearing. Scientific research has shown that the human hearing range reaches up to 23,000 Hz, while cats can reach 85,000 Hz. This frequency is exactly the sound made by mice. Nowadays, cats focus on listening to the sound of cat food cans or biscuit boxes being opened, and their skills keep pace with the times. Many people may not know that a cat’s ears have 32 muscles. The two ears do not affect each other and can rotate at will. In fact, human ears only have three muscles. Compared with cat ears, human ears are much worse and their hearing is much weaker.

In short, the above are the characteristics of cats.
