When you gently caress the soft fur of the "Meow Star Man" and whisper softly in its ear, it will make a comfortable snoring sound; When you yell at it and convey an unfriendly message, it will also raise its ears, open its mouth and "ha" you, emitting a warning breath. At this point, we would think, does the cat understand our language?

　　To answer this question, we might as well learn about a piece of knowledge - neurons.

　　Neuron, the fundamental structural and functional unit of the nervous system. The number of neurons can be used to measure the intelligence level of organisms. Generally speaking, the number of neurons in the human brain is approximately 86 billion. The animal that has the closest relationship with humans - dogs - has over 500 million neurons, while cats have only half of them, about 250 million.

　　So why are many cats or dogs able to demonstrate that they can understand human speech and even engage in some human behavior? In fact, according to research, most of them only stay in the simple discrimination stage, or undergo long-term and complex repetitive training to make simple conditional reflexes to our human "instructions", rather than being able to truly understand our speech. But we cannot deny that even if they cannot understand, they can react to certain behaviors of our humans and interact effectively with them, after all, they are also very intelligent.

　　Charlotte de Muzong, an animal behaviorist at the University of Paris Nanterre in France, said that although cats can't understand your language, they may understand your meaning. We don't need to be depressed about the fruitless communication with them, because they are independent and cold. If they don't want to interact, they also have the right to choose to ignore it.
