Have you been noticing your cat sigh when it is about to sleep, or just suddenly when it’s sitting by the window doing nothing? Don’t worry. It is perfectly normal for a cat to sigh – and we are here to explain why!

Yep. Cats sigh.

Cats yawn, grunt, groan, sneeze, burp, fart, get hiccups – and they sigh. It is completely normal for them to do so.

Cats often sigh to express their contentment, relaxation, or boredom!

Sighing is a long, deep breath that normally indicates the happy or relaxed mood of a cat. But many people have mistaken it to be a sign of depression or discomfort like of humans.

We often tend to get surprised or weirded out when someone not human does something we’re used to seeing only humans do – isn’t that why the craze for parrots talking hasn’t died out despite us getting used to the fact that parrots can mimic human tongue?

Well, then what is the sound like, and what could be the other reason?

I guess we need more points, let’s dig for more.

the truth about cat's sigh;why do cat sighs

Why Do Cats Sigh?

Normally the sigh of the cat means it is happy and relaxed. Just like humans, it releases long breaths as they relax.

This is their way of telling people that they are content.

Though different researchers put different theories behind the sigh of this mammal but the relaxation theory is more acceptable.

Humans normally take sighs as a negative emotion. Being complex beings, humans have a lot of plans to accomplish and work to regret while cats have no such plans. They live and react to the present moment.

Some cats sigh before falling asleep, it seems to be a common reflex.

Cats are quite chatty animals, though their nature usually depends on their breed. Sighing can be assumed as one of their method of talking to you.

Let’s assume you played a chasing game with your cat and after the game, she lies down with a sigh. This sigh is of contentment. Take it as a compliment.

Watch when you treat her with her favorite thing, that sigh will be of happiness.

Sometimes, cat closes their eyes partially, which indicates pleasure

In nutshell the reason behind the cat’s sigh can be:

Why Do Cats Sigh?

1. Biological

Every mammal has lungs, which are vital for the process of respiration.

Cat’s lungs are like human’s and serve the same purpose. So, a sigh is a long breath that refills the alveoli. Without a sigh, the alveoli might burst down.

Silvia Pagliardini said ‘sighs keep the tiny air sacs in the lungs, the alveoli, from collapsing, and maintain the exchange of oxygen and carbon dioxide.’

Too much sigh might be an indication of underlying respiratory disease.

2. The Emotion

Cats normally sigh when it is relaxed. Don’t confuse it with the boredom sigh of humans for cats in case of boredom and frustration won’t stop making the irritable noise and in depression, they won’t meow a word!

It might take a deep breath while lying down in her place which shows that it is relieved to be here and is emotionally stable.

Sigh is similar to the other relaxation techniques of the cat-like; licking, suckling, and kneading.

They have no sense to regret their past mistakes, nor it worries about their future.

So, what do they express? Its current emotion!

With a deep and long sigh, your little friend might be telling you “hey Hooman, I am very happy!” or “oh! It’s so exciting!” or even “ah! I am so tired, finally, it’s my bedtime.”

It can be whatever.

In most cats, the sigh is not a topic of worry.

These fuzzy creatures are carefree, they don’t care about what’s happening around the world or which forest is burning. All it does is play around the house with the wool ball.

Sigh is a very positive sign, this means your cat is absolutely happy in your house.

In fact, you should feel relaxed and happy!

3. Cats Are Sentient Beings Too!

Sentience, although the most complex in humans, isn’t just a gift to the homo sapiens species. Animals, and now even plants, have shown to have some level of sentience – the flora and fauna around us are alive, not just in the literal, scientific sense – but in the sense of the philosophy of life and existence.

Elephants are known to suffer from depression if they lose their loved ones, dogs are known to grieve losing their human homies, and likewise, cats aren’t any different. Cats too, like their domesticated pet counterpart, have emotions that are expressed in different ways by different cats.

Although a cat sighing may not always sound like a human, it may be a higher pitched mrrr instead of a humanly hmpff – but cats do sigh. And often, cats sigh for the same reason as humans do – to express themselves and their current emotional states.

6. To Relax

This is common to both cats and dogs – they often let out a huge sigh right before they pass out into deep sleep.
