The cat's facial expressions are more complex than expected: 276 different facial expressions were observed. In addition to the mouth and eyes, the movements of the ears, nose and whiskers were important for cats.
Overall, 45 percent of the facial expressions observed were friendly and did not correspond to the “Grumpy Cat’s myth at all” The study subjects even showed the smiling “play face” familiar from dogs. In order to understand this, a follow-up study is planned. But this requires more data from wild cats.
