Cats are often seen as mysterious pets: independent, hard to read, sometimes even aloof. But a new scientific study now shows that it’s not necessarily cats that are hard to understand—it’s us humans. Our assessment of how a cat feels apparently depends much more on context, environment, and our own mood than previously thought.
Even Experienced Cat Lovers Often Misjudge Cats
How we perceive our cats in everyday life directly influences how we interact with them. It is crucial for recognizing signs of stress or illness, correctly interpreting behavior, or misinterpreting it, and even deciding whether to let our cat roam freely.
Previous studies have already shown that cat owners often struggle to reliably read their pets’ emotions. A recent study from Australia found that even experienced cat lovers often overlook early warning signs of stress or discomfort, especially during play (PETBOOK reported). The new study from the U.S. now provides experimental evidence for how strongly external factors can distort this perception.
Same Cats–Different Background
The study was published in December 2025 in the scientific journal “Anthrozoös.” It centers on a simple yet astonishing question: Can our assessment of a cat’s mood change even though we see the exact same cat, just in a different environment?
To find out, the research team showed 665 participants images of twelve cats, presenting them multiple times but with AI-generated backgrounds of indoor or outdoor settings.
Participants were asked to assess both the presumed emotional state of the cat and their own mood while viewing. This approach made the study particularly exciting: It experimentally controlled for the first time how much context influences our interpretation of animal emotions.
The key finding: People consistently rated cats more positively when they saw them indoors—even if they believed cats should be allowed to roam freely outside.1
Indoors vs. Outdoors
For data collection, the researchers recorded the following parameters:
- 24 images per person, showing the same cats in different contexts.
- Indoors vs. outdoors with AI-generated backgrounds.
- Emotional self-assessment of participants was separately queried.
- Additional factors such as cat ownership, personal experiences, and beliefs about free-roaming were statistically considered.
This resulted in a total of 665 fully evaluated surveys that contributed to the findings.
Cats Indoors or With Black Fur Appear “Happier”
The results are surprisingly clear:
- Indoors lead to more positive ratings: People rated cats significantly more positively when shown indoors. Even those who believe cats should definitely be allowed to roam freely gave better “emotional scores” to cats indoors.
- Outdoor images were associated with greater arousal: Cats outdoors were more often described as alert, tense, or energetic.
- One’s own mood directly affects cat assessment: Those who felt good while viewing an image later rated the same cat as more positively inclined. This is a strong indication of emotional projection.
- Cat owners rated animals more frequently as “positive”
- Fur color influences perception—and breaks stereotypes: Participants considered black cats to be emotionally more positive than orange or tabby cats. This contradicts classic superstitions and shows how changeable stereotypical perceptions can be.
Subtle Environmental Cues Influence How People Interpret Cat Emotions
“Our research shows that even subtle environmental cues can influence how people interpret cat emotions,” says Monique Udell, professor at Oregon State University and lead author of the study, in a press release from the university. “Understanding these perceptions is important for human-cat interaction and cat welfare.”
Since the images used AI-generated backgrounds, it remains unclear whether other, realistic contexts would produce the same effects. Additionally, the researchers only analyzed the viewers’ perception—not the actual emotion of the animals.
At the same time, the large sample size and controlled study design provide an excellent basis for further exploring the role of context in animal emotion perception. This study represents an important step toward a better, more sensitive understanding of cats.

Significance for Everyday Life and Animal Welfare
“At the end of the day, our perceptions influence how we evaluate what cats communicate to us and how we care for them,” concludes Udell. Challenges in interpreting and dealing with cat behavior in households can lead to frustration or overlooked health issues and are one of the main reasons cats end up in shelters, according to the scientist. Therefore, understanding the needs, behavior, and emotional state of humans is crucial for the welfare of cats and the human-animal relationship.
The findings could be used in the future to:
- Better educate pet owners,
- Optimize shelter photos (indoor backgrounds increase adoption success),
- Improve visual communication about animals,
- Rethink emotion recognition in cat research.
Conclusion: Cat Communication Starts with Ourselves
The study clearly shows: We interpret cat emotions not only from what the animals show but also from what we feel and the environment we see. Whether it’s an indoor background, fur color, beliefs about free-roaming, or one’s own emotional state:
All these factors shape how we assess a cat’s mood.
For cat owners, this means: To truly understand your cat, you should not only pay attention to facial expressions and body language but also to yourself. Sometimes the greatest distortion lies in our own perspective.
