When you look at your kitty cat, you don’t know what’s happening inside their brain. But it is helpful to have a good idea of how to recognise feline emotions from their behaviour.

For ease of explanation, let’s consider feline body language in two groups: signals aimed at decreasing distance (purr purr, come closer) and signals that mean the cat is trying to increase distance.

Pay attention to all your cat’s body parts when trying to understand their body language, and to the speed at which actions happen. For example, a slow blink is a sign of a relaxed cat (and it’s a good idea to slow blink back), whereas a rapid blink with scrunched-up eyes is a sign of fear.

Essentially, the more open your cat’s body position, the less stressed they are. A cat who is lying on their side or their back with their legs stretched out, their tail loose and out, and their belly on show is relaxed. Their eyes might be fully or partially closed or doing a slow blink at you if you’re lucky, and the ears and whiskers will be in a normal position.

When you should give your cat space

Signs that your cat wants you to stay away include a swishing tail, rippling skin, a flattened body (as if trying to be invisible), the limbs and tail tucked in close to the body, hissing, spitting, and caterwauling. If you see these signs, don’t approach your cat, because they may feel forced to defend themselves with tooth and/or claw.

Instead, give them space. If you were petting them, stop—before they have to make it even more clear that enough is enough. It is always best to let a cat approach you and give them a choice of whether or not to interact with you.

How to tell if a cat is frustrated

Cats can become frustrated because they are bored, unable to access something they want (such as food or a bird they can see through a window), or unhappy at being in a shelter, where they may make a mess of their cage by tipping out their food and water bowls, knocking over their litter tray, and attempting to escape by putting their paws through the bars, pushing their body against the cage door, and biting the cage.

Signs of frustration include this kind of destruction and trying to escape, as well as meowing a lot, pacing up and down, and rubbing on things a lot.

They will be highly aroused with a thrashing tail, and you may see their skin ripple too. Be very cautious with a cat in this state, as you may be at risk of a redirected bite — one where you aren’t the cause of the aggression, but you happen to be there, so you get the result of it.

You can help to prevent frustration by figuring out what the cat wants and finding ways to safely provide it to them.

How cats express emotion with their face

Humans often look at facial expressions for clues about emotion, and yet the fact that there’s such a wide variety in the shapes of cats’ faces makes it hard to learn to read their emotions this way. But scientists are making advances in this tricky area.

In one study, they looked at the faces of cats in shelters both during petting (with a hand or a touch stick) and while just in the cage. Because of the different face shapes, the researchers looked at how the face changed from a normal position.

Being afraid was associated with a low, flat posture, with hiding, and with retreating and moving back, often with a freeze (a moment of keeping still) beforehand. As well, they found that the direction of the cat’s head was associated with their emotions; a leftward gaze or turn of the head when the cat was fearful, and a gaze or turn to the right in a relaxed cat. Some of the cats in the study were frustrated, and signs included licking the nose, the tongue being visible, and hissing.

Scientists have also developed and validated a feline grimace scale that may be useful to veterinarians wondering if a cat is in pain or not.

The facial signs they identified are a change in the muzzle shape (oval and bulged rather than round); changes in the position of the tips of the ears (far apart and facing out); a narrowing of the eye area with the eyes potentially partly closed; and the whiskers being forward, straight, and away from the face, instead of the usual lovely, relaxed curve.

As well, the head was lower than usual, below the shoulders or with the chin tucked close to the chest. This scale is designed for professional use and these signs may not be easy to spot, but if you are ever concerned about your cat’s health, always see your veterinarian.

How easy is it to read a cat’s body language?

Cats’ reputation for being hard to read is part of their mystique. And we love them almost because of this, rather than despite it. If you find it hard to read your cat’s body language, you are not alone.

Most people performed worse than chance when scientists showed them videos of cats and asked them to say if the felines were feeling positive or negative emotions (happy or unhappy, if you like). Only 13 per cent of people were good at it, and they weren’t your average pet owner—rather, they were people who worked with cats, such as veterinarians, vet techs, and people who work in animal shelters.

Experience with many cats may play a role in discerning these emotional shifts, but it could also be that for our own cats in our own homes, perhaps we don’t always see the full range of emotions.

Hopefully, the average cat owner does not see too many negative emotions in their cat. But it’s certainly worth paying attention to your cat’s body language to learn more about how to tell what they’re feeling. That’s useful information that will tell you what your cat does and doesn’t like. (But don’t stare, because that makes cats uncomfortable.)
