One of the weirdest things I ever saw was in a zoo in Saigon. Was a tiger enclosure, just with bars no glass, and inside was the tiger chilling and BUNNY RABBITS
The bunnies were just wandering around, eating stuff, not far from the tiger and ignoring it. The tiger was ignoring the bunnies too. Then some absolute douchebag started throwing empty softdrink cans at the tiger trying to make it react...motherfucker I wanted to throw him in there with it.
Still don't get the bunnies though, at first I thought they were food but they had zero fear of this giant predator.
