If a cat purrs at a person, will the "person who snores" be considered by the cat as a gesture of goodwill to the cat?
Human snoring can be noise for cats. Some time ago, there was a video on the Internet, the male owner was sleeping on the sofa, the snoring sound was earth-shattering, and the cat was so noisy that the cat slept next to him and slept with his paws covering his ears, with a disgusted expression, funny and cute.
The image comes from the Internet cats are aware of their "purr" sounds and use them for friendly communication.
A cat purr is a sound produced by a cat's specific breathing rate that causes the vocal cords to vibrate the second vocal cord, which is usually produced when the cat is extremely comfortable.
Human snoring is caused by decreased nerve excitability during sleep, muscle relaxation, and blockage of pharyngeal tissues, causing the upper airway to collapse, and when the airflow passes through the narrowed area, it creates vortex currents and causes vibrations, resulting in snoring.
According to the principle of purring sound, they are all produced by vibration, but the sound volume is completely different.
The lowest sound that the human ear can hear is 1 decibel, below 20 decibels is very quiet, 25-30 decibels is the most comfortable sound, and cat purr is generally around 25 decibels, which is one of the reasons why humans will fall asleep more easily when they hear cat purring.
As a cat with 3 times the hearing of humans, more than 20 decibels can already be called noise, and the snoring sound of about 50~80 decibels of humans has far exceeded the noise standard that cats can hear.
A person's snoring is not considered a gesture of favor by a cat at all.
The picture comes from the Internet, but the cat that has lived with the owner for a long time does not resent the owner's purring, but this behavior will make the cat feel at ease.
Some scientists have done an experiment in order to know whether the cat knows the owner sleeping, and compared the cat's reaction after the owner fell asleep and when he was awake, and found that the owner's breathing and snoring after falling asleep would make the cat behave very relaxed.
For cats who are worried about the country and the people, the shovel officer can make this sound, indicating that this is in a normal state, but if the purring suddenly stops, the cat may seem cramped and uneasy.
