Laughter in animals

Laughter in animals other than humans describes animal behavior which resembles human laughter.

Several non-human species demonstrate vocalizations that sound similar to human laughter. A significant proportion of these species are mammals, which suggests that the neurological functions occurred early in the process of mammalian evolution.^[1] Laughter as communication is found in over 60 species.^[2]
