What? Did you know that kittens can sigh too? Sighing is not exclusive to humans. In a 2016 study, it was found that sighing is a reflex that occurs frequently. And the number of related neurons it regulates is very small, in other words, this is a very simple and easy-to-achieve reflex.
So the researchers speculate that any mammal with the relevant neurons may be able to "sigh." Cats are no exception. Many owners have observed this phenomenon... So why do cats sigh? Is it about "sorrow"?
Why do cats sigh?
First of all, to be clear, there are differences in the emotional expression of cats and humans.
For example, the way humans express happiness:
✔ laugh out loud
✔Dancing and more...
And the way cats express happiness:
✔ grunting
✔ squint
✔ Vertical tail and more...
So we can't directly use "and so on" to judge the specific meaning of each cat's actions~ In this case, what exactly is the cat's sigh expressing? Let's see what cat behaviorists say...
Reasons why cats sigh
▌Conjecture 1 Physiological needs
It may not mean anything else, but cats are purely exercising lung function. In experiments, the researchers found that human infants experience an involuntary sigh every 50-100 breaths. They speculate that this behavior may help exercise the function of the lungs, develop a good breathing rhythm, and is common to all mammals, so cat sighing may be the same.
▌Conjecture 2 relax yourself
Some veterinarians think it may be the cat relaxing. In cats, it may be through sighing (compressing the alveoli) to release excess carbon dioxide while taking off the effort and relaxing other muscles in the body. From this point of view, some people think that "sighing" may also occur before the cat falls asleep, which is a sleep preparation action of the cat.
▌guess 3 adjust breathing
"Sigh" is a kind of "exhalation". When the cat's position changes or after the exercise is over, it may be adjusted by "sighing". For example, if a cat walks on the floor well, if you hold the cat in your arms and hold it tightly with your hands, it may trigger "cat's sigh"...or after the licking is over, the cat may sigh to intervene breathing rhythm...
▌Conjecture 4 Express emotions
Because cats and humans express their emotions differently, in their world, it is not necessarily sad or sad that they "sigh"... Veterinarian Beverley Ho believes that this is a sign of cats being happy and comfortable. Because most of the time, cat sighs are accompanied by positive emotions such as squinting and ears facing forward.
However, some people have observed that cats sigh when they have nothing to do at home, so they think that "sigh" is also an expression of boredom by cats... But in general, "sigh" may express more positive emotions in the cat world.
