Since his newfound friendship, Amur has eaten raw meat rather than living food, but nobody knows if or when he'll switch back. Meanwhile, Amur's been acting defensive of his goat friend.
On Thursday, one of the zookeepers shared a tense moment with Amur. "[He] hissed at an employee who feeds the tigers, as if to tell him, 'Hey, don't you ever approach my friend.' Before that, he never showed any aggression towards staff," the zookeepers told RT.
It goes to show that animals don't just need food, water and space to move around. Sometimes, they need a friend too.
