Brain structure
The average brain capacity of a cat is about 25ml. According to the brain quotient (the ratio of the relative volume of the brain to the weight of the animal itself), that is, the emotional quotient of the cat is about 1. Emotional intelligence can show IQ, but the brain is not as simple as you humans think, and the number of nerve cells in the cerebral cortex also needs attention. There are about 300 million nerve cells in the cerebral cortex of cats.
sight
Cats have excellent night vision. There is a layer of "photographic film" under their eyes, which can reflect any light passing through the retina back to their eyes, thus increasing their sensitivity to dim light.
If the cat slave does something shameful at night ... it's stealing food! Stealing food! ..... you can have a panoramic view of the cat. In addition, the cat's eye is also very adaptable to tracking fast-moving prey, and it is effortless to play the game of hiding the ball in the cup.
(sense of) hearing
The relative size of the cat's middle ear is larger than that of the dog's, which makes the cat's ears feel a wider frequency range, and the hearing frequency is about 55 Hz to 79,000 Hz. Sensitivity is comparable in all mammals, and ultrasound in rodents is not a problem.
There is a saying-Mickey will be silent and Minnie will cry.
smell
Compared with dogs, the cat's nose plow is more sensitive, and it can analyze the chemical information of the odor left by other cats, which is convenient for communication with the same kind. The cat next door to Zhang Yi has a new girlfriend, and Li Damiao across the hall has no idea what food it ate.
short-term memory
Cats' short-term memory can last 16 hours, but cats only remember things that can benefit them. Always thinking about one or two, not eight or nine. Meow meow is really a philosopher.
long term memory
Cats can learn hunting skills by observing the behavior of humans and female cats. Their memory and decision-making power are equivalent to those of human children aged 2-3.
For example, cats will manipulate you by snoring.
Studies have shown that cats' meowing and purring are languages specially developed for human beings. They are acquired in the process of your interaction with people, but cats don't use this language to communicate with people. However, if you think that this kind of sound just means that they are comfortable, you may be wrong. When they purr at you (sometimes mixed with meowing), you should be careful: it may be manipulating you.
Karen McComb(2009) analyzed the information transmitted by cats when they purr at humans, and found that when cats want something from you, the purr is different from usual. The researchers collected 10 cats' calls in foraging and non-foraging states, and played these sounds to 50 people, some of whom owned cats and some didn't. It turns out that even people who have never owned a cat can hear the difference between these two sounds. They think cats are more anxious and unhappy when they are foraging, and they will want to help them more when they hear it.
Mccomb calls this kind of snoring "pleading snoring", which only appears when they need human beings to do something for themselves, and its amplitude and frequency are much higher than that of "non-pleading snoring". And sometimes, they purr and meow, which is the easiest way to arouse human emotions.
Mccomb believes that cats take advantage of human sensitivity to this sound. 1985 has proved that the cry of a cat for help is similar to that of a baby (Buchwald,1985); Mccomb also compared the "incited" purr of a cat with the crying of a healthy baby, and found that the frequency of the two is very close (300-600 Hz), which will arouse each other's desire for care.
Therefore, cats may deliberately exaggerate their calls to attract their owners' attention.
Many times, your understanding of cats is only romantic.
1. When a cat rubs you, it doesn't mean it likes you; It's just announcing possession to you.
If you think that the cat rubs you out of love, you are also wrong. In fact, it is telling other cats: I have this person. This is because in the cat world, every cat has a unique smell, and they can distinguish themselves from other cats' smells. And it will feel that if it rubs its own smell on you, you are its "territory" (Jacques, 20 12).
On the other hand, they are still trying to remove your smell from themselves. Cats like to lick their bodies and fur to clean themselves, but do you know what they try to lick? This is the smell when people lick themselves most often, which is to get rid of people's smell after being touched by human beings.
2. Only when the cat winks at you does it show kindness; If they just stare at you, they don't welcome you near at all.
Cats have a strong sense of self-protection, both for other cats and for you. When your cat looks at you from a distance, you may think that it is being nice to you, but in fact, if your cat stares at you for a long time without blinking, it is a sign of strong defensive feelings-indicating that it is defending its territory (such as a litter box, an area or other things that it thinks belong to itself), and you are not welcome to enter this territory. When a cat announces its territory to other cats, it will also have such eyes. If a cat squints at you, it means that it is either in a state of fear or attack. Only when they look at you and blink at the same time, this is a welcome signal.
Besides, if you want to be nice to a cat, you'd better not stare at it without blinking. In this case, it will think that this is a signal of attack, or you want to drive it away.
The cat can actually understand what you are saying, but it just doesn't want to talk to you.
Studies have proved that your cat can fully understand your calling its name and can even accurately distinguish your voice from other people's voices. If it often ignores your calls, it can only show that it really doesn't care about your needs.
20 13 The research published in the Journal of Animal Cognition conducted experiments on 20 domestic cats (Saito, 20 13). When the owner of the cat is out of sight, the researchers will play the voices of four people, three of whom are strangers. 1 is the real owner of the cat. When hearing the stranger's voice, all 20 cats have involuntary reactions, of which 50% cats shake their heads and 30% cats move their ears. But only two cats spontaneously responded by words and actions, that is, meowing or wagging their tails.
They do recognize their owners' voices: compared with the voices of strangers, most cats (75%) shake their heads and move their ears more when they hear their owners' voices, but that's all-the proportion of them responding with practical actions has not increased.
Researchers believe that this may explain that cats are lonely creatures-they are not domesticated by humans and do not want to meet human expectations of them.
However, having said that, I still want to be played by the cat master ~ the last picture:
