Domestic Kangaroos
Kangaroos have shown they can use body language to ask humans for help, busting earlier beliefs that only domesticated animals have such an ability.
Alan McElligott and colleagues at the City University of Hong Kong tested 16 roos living in captivity with the same methods used to study horses, dogs and goats. After blocking food from the kangaroos with a transparent box door that made it impossible for the marsupials to get it, they observed the animals’ behavior. The roos almost always turned to a nearby human for help. “They’d look straight up at my face, like a dog or a goat would do, and back at the box, and some even came up and scratched my knee like a dog pawing [for attention],” said McElligott.
