Elegant, aloof, and independent—these are probably the most common words used to describe cats.
However, regardless of a cat's actual personality or whether it enjoys interacting with people, "hiding its weaknesses" remains an instinct ingrained in its bones, a valuable asset accumulated through natural competition where the fittest survive.

We can usually make a comprehensive judgment on a cat's mood and health by observing changes in behavior, posture, and activity level.
However, if you only look at a cat's facial expressions, are you confident that you can accurately judge its emotions?
For cats, who are very good at hiding their emotions, recognizing subtle changes in facial expressions is very important.
Humans possess a natural talent for quick and subtle facial expression processing, which makes us adept at detecting fleeting and minute changes in expression. In addition, there are indeed some similar facial expressions among mammals.
Therefore, out of curiosity about the extent to which humans can understand cats, LC Dawson et al. designed a study on whether humans can accurately identify cat emotions and, based on the results, identified the types of people who are better at recognizing cat emotions.
The study selected 40 short video clips of cats (20 showing positive emotions and 20 showing negative emotions, excluding obvious changes such as airplane ears) using certain criteria. Except for the cats' heads, the rest of the images in the videos were obscured. Each volunteer watched 20 of the videos and judged whether the cat's emotional expression in each video was positive or negative. A total of 6329 volunteers completed the study.

Volunteers were more likely to accurately identify cats expressing positive emotions (especially active cats), but their overall average score was low (11.85/20). Researchers believe that recognizing subtle changes in a cat's facial expressions is challenging, but some people are indeed very good at it!
After analyzing the research results, researchers found that differences in cat-owning experience had little impact on the findings. In other words, whether you're a new cat owner for a month or a seasoned one for ten, a single-cat household or a multi-cat household, or a close or distant relationship with your cat: those who cannot understand their feline overlord's emotions will never be able to.
