Study Finds That 65 Different Species of Animals Laugh To Express Happiness
Laughing rats and dogs may seem more like something out of a Disney animated film than of real life, but they do exist. While neither species laughs like a human giggles, each has their own joyful noise. A recent UCLA study published in Bioacoustics discovered that 65 animal species have their own form of “laughter.” Among the species who make such playful vocalizations are seals, dogs, rats, and mongooses.
