Summary: People can infer a cat’s affective state from subtle aspects of their facial expressions.

Cats have a reputation for being hard to read, but new research from the University of Guelph has found that some people are veritable “cat whisperers” who excel at deciphering subtle differences in cats’ faces that reveal mood.
Women and those with veterinary experience were particularly good at recognizing cats’ expressions — even those who reported they didn’t feel a strong attachment to cats, the large study found.
“The ability to read animals’ facial expressions is critical to welfare assessment. Our finding that some people are outstanding at reading these subtle clues suggests it’s a skill more people can be trained to do,” said Prof. Lee Niel, who led the study with Prof. Georgia Mason, both from U of G’s Campbell Centre for the Study of Animal Welfare.
The only research so far on readings cats’ faces has focused on expressions of pain. “This study is the first to look at the assessment of a wider range of negative emotional states in animals, including fear and frustration, as well as positive emotional states,” said Mason.
Published recently in the November issue of Animal Welfare, the study recruited more than 6,300 people from 85 countries who were asked to watch 20 short online videos of cats from a collection of 40 videos, gleaned mostly from YouTube, and complete online questionnaires.
The videos showed cats experiencing either positive emotional states (situations the cats had sought out, such as being petted or given treats), or in negative states (such as experiencing health problems or being in situations that made them retreat or flee). Each video was focused on the cat’s face -its eyes, muzzle and mouth. None of the cats showed expressions of fear, such as bared fangs or flattened ears, since these facial expressions are already widely understood.
Participants were asked to judge whether each cat was in a positive state, a negative one, or if they weren’t sure.
Most participants found the test challenging. Their average score was 12 out of 20 — somewhat above chance. But 13 percent of the participants performed very well, correctly scoring 15 or better — a group the researchers informally called “the cat whisperers.”
These people were more likely to be women than men, and more likely to be veterinarians or vet technicians. Younger adults also generally scored better than older adults.
“The fact that women generally scored better than men is consistent with previous research that has shown that women appear to be better at decoding non-verbal displays of emotion, both in humans and dogs,” said Mason, who worked on the study along with post-doctoral researchers Jenna Cheal and Lauren Dawson.
Surprisingly, being a cat lover made no difference at all, since reporting a strong attachment to cats did not necessarily result in a higher score.
The finding that some people are skilled at reading cats’ faces suggests that others could be trained to do so as well.
Humans can identify cats’ affective states from subtle facial expressions
Although cats’ popularity as pets rivals that of dogs, cats are little studied, and people’s abilities to read this apparently ‘inscrutable’ species have attracted negligible research. To determine whether people can identify feline emotions from cats’ faces, participants (n = 6,329) each viewed 20 video clips of cats in carefully operationalised positively (n = 10) or negatively valenced states (n = 10) (cross-factored with low and high activity levels). Obvious cues (eg open mouths or fully retracted ears) were eliminated. Participants’ average scores were low (11.85/20 correct), but overall above chance; furthermore, 13% of participants were individually significantly successful at identifying the valence of cats’ states (scoring ≥ 15/20 correct). Women were more successful at this task than men, and younger participants more successful than older, as were participants with professional feline (eg veterinary) experience. In contrast, personal contact with cats (eg pet-owning) had little effect. Cats in positive states were most likely to be correctly identified, particularly if active rather than inactive. People can thus infer cats’ affective states from subtle aspects of their facial expressions (although most find this challenging); and some individuals are very good at doing so. Understanding where such abilities come from, and precisely how cats’ expressions change with affective state, could potentially help pet owners, animal care staff and veterinarians optimise feline care and welfare.
