Brain structure
The average brain volume of a cat is about 25 milliliters, and if you calculate according to the encephalization quotient (the ratio of the relative volume of the brain to the animal's own weight), or EQ, a cat's EQ is about 1, which is an indication of intelligence. EQ can indicate the level of intelligence, but the brain is not as simple as you humans think, the number of nerve cells in the cerebral cortex, also need to pay attention to. There are about 300 million nerve cells on a cat's cerebral cortex.
Vision
Cats have excellent night vision, with a layer of "photoreflective film" under their eyes that reflects any light passing through the retina back to the eye, thus increasing the eye's sensitivity to dim light.
Cat slaves who do anything shameful at night ...... are talking about stealing food here! Stealing food! ...... can all be caught in the bottom of the cat's eye. Additionally, the cat's eye is highly adapted to tracking high-speed moving prey, making it effortless to play the game of cups hiding small balls.
Hearing
The relative size of a cat's middle ear is larger than a dog's, which allows the ear to perceive a wider range of frequencies, hearing frequencies from about 55 Hz to 79,000 Hz, with sensitivity that carries all mammals, and rodent ultrasound notwithstanding.
What's the saying - Mickey will be silent and Minnie will cry.
Sense of smell
The cat's nose-plow is more sensitive compared to the dog, and is able to analyze the chemical information of smells left behind by other cats, making it easy to communicate with its own kind. It knows exactly what kind of food the cat next door's Zhang Yi has got a new girlfriend, and what kind of food the cat across the street's Li Dajiaow has eaten.
Short-term memory
The cat's short-term memory can last up to 16 hours, but what the cat remembers is only the things that can bring benefits to itself. Always think one or two things, not eight or nine. Meow is truly a philosopher.
Long-term memory
Cats can learn hunting skills by observing the behavior of humans and female cats, and their memory and decision-making are equivalent to that of a human 2-3 year old child.
Cats can manipulate you by the sound of purring, for example.
Studies have shown that the cat's meows and purrs are language developed specifically for humans, learned during your interactions, and that cats don't communicate with each other in such a language. However, you may be wrong if you think that this sound just means they are comfortable. When they purr and purr at you (sometimes interspersed with a meow), watch out: they may be manipulating you.
Karen McComb (2009) analyzed the messages cats convey when they purr at humans and found that cats purr differently than they normally do when they are asking for something. The researchers collected the purrs of 10 cats in a foraging state and a non-foraging state, and played the sounds to 50 people, both those who owned cats and those who did not. It turned out that even people who never owned cats could hear the difference between the two sounds, and they thought the cats' purrs in the foraging state were more urgent and unhappy, and that they would be more likely to want to help them after hearing them.
McComb calls the purrs "solicitation purrs," which occur only when they need a human to do something for them, and are higher in amplitude and frequency than "non-solicitation purrs. The amplitude and frequency are much higher than the "non-solicitation purrs". And sometimes they will purr and meow at the same time, which is the most emotionally arousing sound.
McComb suggests that cats take advantage of human sensitivity to such sounds, as evidenced by a 1985 study that found similarities between the purring of cats and the crying of infants (Buchwald, 1985); McComb also compares cats' instigating purrs with those of healthy infants, and the purring of healthy infants to the purring of healthy infants. McComb also compared the "instigating" purr of a cat with the sound of a healthy infant crying, and found that the frequencies of the two were very close (300-600 Hz), and that both stimulated the desire to care for the other.
Thus, cats may be intentionally exaggerating their purring to attract the attention of their owners.
Often, your understanding of cats is just self-serving
1. When a cat is rubbing up against you, it doesn't mean it likes you; it's just asserting possession over you.
If you think a cat is rubbing up against you out of love, you're wrong, too. In fact, it's declaring to the other cats, I've got possession of this person. This is because in the world of cats, each cat has a unique scent, and they can tell the difference between their own and other cats' scents. And it feels that if it rubs its scent on you, you are its "territory" (Jacques, 2012).
On the other hand, they are still trying very hard to remove your scent from themselves. Cats love to clean themselves by licking their bodies and fur, but do you know what they are trying to lick off? It's human odor. The most common time they lick themselves is after being petted by a human in order to remove the human smell.
2. The only time a cat blinks at you is when it's showing goodwill; if it's just staring at you without looking away, it means they don't welcome your proximity at all.
Cats are very self-protective, both of other cats and of you. When your cat looks at you from a distance, you may think it's making a pass at you, but in reality, if your cat stares at you long and unblinking, it's a sign of a strong defensive emotion - a sign that it's defending its own territory (such as the litter box, an area, or something else it thinks is its own), that This territory is not welcome. A cat will also have this look in its eyes when it's asserting its territory to other cats. And if a cat squints its eyes up at you, it means it is either in a fearful mood or an aggressive mood (Amy Shojai, 2016). The only time they look at you while blinking their eyes is a sign of welcome.
And it's also best not to stare at a meow without blinking if you're trying to be nice to it, in which case it'll think it's a sign of aggression or that you're trying to get rid of it.
3. Cats actually understand what you're saying, they just don't want to talk to you.
Studies have proven that your cat is perfectly capable of understanding what you're calling it, and can even accurately distinguish between your voice and other people's voices. If it regularly ignores your calls, it only means that it really doesn't care about your needs.
A 2013 study published in the Journal of Animal Cognition conducted experiments on 20 domesticated cats (Saito, 2013). When the cat's owner was not in the cat's line of sight, the researchers played the voices of four people, three of which were strangers and one of which was the cat's real owner. Upon hearing the stranger's voice, all 20 cats showed an involuntary response, with 50% of the cats shaking their heads and 30% of the cats twitching their ears. But only two cats responded spontaneously with words and actions, such as meowing or wagging their tails.
They did recognize their owners' voices: most cats (75%) responded more to the sound of their owner's voice by shaking their head and flicking their ears than they did to the sound of a stranger's voice, but that was about it -- the proportion of cats that responded with actual actions did not increase.
The researchers believe this may indicate that cats are solitary creatures - they are not submissive to human taming and do not want to fulfill human expectations of them.
But, having said that, it's still a willingness to be toyed with by the cat master ~ on a picture:
