There are a surprising number of animal species that are ticklish.
Various animals, ranging from apes to owls and even camels, share a common response to being tickled similar to that of humans.
“I was amazed about the way apes responded to being tickled – the apes seem to behave in the same way humans and children behave when they are being tickled,” Dr. Maria Davila-Ross of the University of Portsmouth wrote.
Furthermore, aside from the apes, the animals previously mentioned appeared to produce “positive vocalizations” when tickled.
Chickens weren’t on the BBC’s list but a woman named Lisa who lives on a Rockwall, Texas hobby farm says her chicken Francis laughs hysterically when being tickled.
Francis lives on a farm with all sorts of different animals.
Lisa was surprised by Francis’ reaction to physical contact and playful gestures, prompting her to feel compelled to spread Francis’ happiness to a wider audience.
