一直以為被馴養的動物如狗、馬、山羊等才會與人類有互動的認知，但原來袋鼠亦會嘗試與人類溝通。。研究員分別給袋鼠放了食物的盒子，當發現自己無法打開時，會尋找附近的人類協助，並有眼神交流。

it has been thought that domesticated animals like dogs, horses or goats are the only animals that would intentionally communicate with human, but recent study found kangaroos would do that as well. Researchers presented a container with food inside to kangaroos, and after failing to open the box, most of them would find a nearby human for help, and they even make eye contact with human.
