These kids were having a great time at Australia Zoo’s tiger enclosure when one of the tigers became their unlikely playmate. They engaged the animal in an intense game of peek-a-boo through the glass, and reacted with delight as the big cat followed them from one end of the window to the next. Who has the heart to tell them that the ferocious feline was probably just thinking about how tasty they’d be for lunch? Credit: Davie MacRae
