Cats are notoriously "hard to understand", say researchers, and most studies support this view.

A new study has found that most of us can't read a cat's expression.

More than 6,000 study participants from 85 countries, the vast majority of whom were cat owners, watched short videos of cats and judged the animals' emotions. In the end, they scored a failing grade on average. The researchers said, "A cat uses facial expressions to reflect its mood, and if you're good at it, you can read those expressions."

The most prominent features of a cat's face, such as their eyes, ears, and mouth, play a crucial role in conveying their emotions. For example, a relaxed and content cat will have half-closed eyes and gently relaxed ears. This indicates a sense of comfort and ease. Conversely, when a cat is feeling anxious, their eyes may widen, their pupils dilate, and their ears may flatten against their head.

These subtle changes in their facial expression are often accompanied by other body language cues such as a crouched posture or a twitching tail. By paying close attention to these signals, cat owners and enthusiasts can better understand and respond to their cats' needs.

One of the most intriguing aspects of cat facial expressions is their ability to communicate feelings of affection and trust.

When a cat is content and happy, it may display what is known as a "slow blink." This is when a cat half-closes its eyes and then opens them wide again, seemingly as a sign of relaxation and trust. Returning the slow blink is often interpreted as a gesture of friendship and can help strengthen the bond between the cat and the owner.

Furthermore, a cat's mouth can also provide insights into their emotional state. When a cat is relaxed, its mouth will typically be slightly open, with the tip of its tongue just peeking out. On the other hand, if a cat is feeling threatened or defensive, its mouth may be tightly closed, and its lips may be pulled back, revealing its teeth in a display of aggression.

It is important to note, however, that a cat's facial expressions can be subtle and easily misinterpreted. Each cat is unique, and their personalities and experiences may influence their facial expressions. In conclusion, while cats may not possess the same range of facial expressions as humans, they do have the ability to communicate their emotions through subtle changes in their eyes, ears, and mouth. So the next time you interact with a cat, take a moment to observe their facial expressions, and you may be pleasantly surprised by the insights you gain into their world.
