A recent study suggests that goats are drawn to people with a smile on their face. Goats can also distinguish if a person is happy or angry.
The study was published by The Royal Society in order to determine the intelligence of goats in understanding human social cues. 35 goats from a goat sanctuary were used for the research.
Photos of people with happy and angry expressions were hung up. The goats were found to be drawn to the happy photos. This helped researchers come to a conclusion that goats like to spend more time with happy faces.
It was also concluded that "goats can distinguish between happy and angry images of the same person, indicating that they can visually differentiate human faces conveying different emotional valences."
