In the study, published in the journal Scientific Reports, scientists divided pigs' emotions into positive and negative categories.
When they make a short purr, it usually means they are happy; when the purr becomes longer, it means they are dissatisfied.
And when the pig is in pain, it screams.
"Positive emotions often represent an increased chance of their survival, such as getting a reward, food, and being reunited with the mother pig," said Elordi, a professor at the University of Copenhagen. "Negative emotions represent life-threatening threats, such as being beaten and being slaughtered."
