The text states that rats know how to laugh.
Research indicates that rats produce ultrasonic vocalizations when tickled, interpreted as laughter by some scientists. Jaak Panksepp's studies highlight this behavior as a potential indicator of social bonding and emotional states in rats. These vocalizations are distinct from human laughter, occurring at high frequencies inaudible to humans, and are observed in social and playful contexts. This evidence supports the claim that rats display a form of laughter.
