However, whilst the facial expressions of your cat might sometimes physically resemble a human grin, cats do not ‘smile’ in the way that humans do to express their feelings of happiness.

In fact, a cat that pulls their lips upwards and displays their teeth is usually feeling defensive or actively sniffing their environment. That being said, your cat has many alternative ways in which they communicate that they are feeling happy.

How Cats Communicate Their Feelings of Happiness

1. Slow Blinking

The cat equivalent of the human smile is the slow blink. When your cat narrows their eyes and blinks slowly at you, they’re actually smiling with their eyes. In fact, research has shown that when humans narrow their eyes, they become more attractive to cats.

Many cats will even return this expression of narrowed eyes and slow blinking to a human who is displaying it. Try giving it a go the next time your cat is relaxed and see if they ‘smile’ right back at you!

2. Purring

Purring is well known to be a sign of a happy and contented cat. Cats will also sometimes purr when they’re afraid or in pain but it’s usually easy to tell the difference depending on the context of the situation. If your cat is relaxing on your knee and enjoying some chin rubs whilst purring, chances are you have a pretty happy cat!

3. Head butts

When your cat knocks their head gently against you and rubs their cheeks on you, they are ‘marking’ you as theirs with scent from glands that are just in front of their ears. This act of head butting is also referred to as ‘bunting’ and demonstrates that your cat is happy and relaxed in your company. Your cat might greet you this way when they first see you in the morning, or when you return home after work.

4. Kneading

Many cats will ‘knead’ when they’re feeling happy and relaxed. It might be a blanket, your lap, or their bed but the act of kneading is thought to be an instinct behavior that remains from kittenhood when newborns knead their mom and her mammary glands to stimulate the production of milk. This is also why some cats drool when they knead – they are instinctively anticipating food.

As well as being a comforting action that reminds your cat of security and feeding, kneading also releases ‘happy’ pheromones from scent glands in their paws. Many cats will also narrow their eyes whilst kneading – a true expression of happiness.

5. Vocalizing

Some cats will meow or chirp when they are happy. Again, you need to look at the context of the situation as some cats will meow when they’re frightened or in discomfort but if your cat is chirruping away to you as a greeting, or when they’re being petted, chances are they’re just happily chatting away to you.

6. A Straight Tail

Your cat’s tail position can often tell you a lot about their mood. Cats that hold their tail upright are usually happy to see you. If your cat is holding their tail between their legs, it can mean that they are worried or frightened. When a cat whips or thrashes their tail, it usually means that they’re annoyed or agitated.

Cat Expressions That Could Be Mistaken for a Smile

Their Normal Face

A cat’s mouth is often naturally turned up at the corners which can definitely look like they are smiling when in fact, this is just how their face looks! Think ‘resting smile face’!

The Flehmen Response

Cats have an interesting dual scent mechanism, whereby they not only detect smells using their noses but also by a tiny organ called the vomeronasal organ (also known as the Jacobson’s organ) on the roof of their mouths.

This allows a cat to detect pheromones (chemical messengers) by opening their mouth. They also sometimes curl their lips which helps to pass scent over the vomeronasal organ – a motion called the flehmen response, which can look a little like a human smile.

Baring of Teeth

Cats will often pull their lips up and bare their teeth as a warning to other cats, predators, or sometimes humans. It might look a bit like a wide smile but it actually means ‘back off’ – quite the opposite of a smile! You’ll usually be able to tell that this isn’t a friendly expression as it’s often accompanied by growling, hissing, and spitting!

How Can I Make My Cat Happy?

There are plenty of things you can do to ensure your cat is happy and contented. Be sure to spend plenty of quality time with your cat, petting them, playing with them, and sitting with them (or allowing them to sit on you if this is what they enjoy!).

Never force an interaction with your cat as this can make them stressed, but be sure to make yourself available for strokes, cuddles, and playtime when they want them.

Simply getting to know your cat and their likes and dislikes is one of the best ways to ensure that they are happy. Many cats enjoy treats but just ensure that they are fed in moderation and are suitable for your cat. Ensuring that your cat is well cared for, fed a good quality diet, and provided with a regular routine, all make for a contented kitty.

Summary

Although cats do not smile in the literal sense that humans do, they have many other ways of communicating their feelings of happiness. One of the main ways in which cats smile is by narrowing their eyes and slowly blinking.

Cats will often communicate with their owners in this way and if a human blinks slowly at their pet cat, they will often return the gesture by narrowing their eyes and slow-blinking back at them. In other words, cats smile with their eyes instead of their mouths!
