If Hollywood taught us anything it is that you never EVER turn your back on a big cat.
And this heart-stopping footage from a zoo in Japan shows us exactly why.
The amateur video, captured at Chiba Zoo shows a little boy engaged in a staring contest with a large lion.
The little boy then turns his back on the lion but the lion being, well a lion doesn’t see a little boy, he sees a small yellow animal that looks like dinner.
The footage shows the lion then lunging for the two-year-old boy – dressed in a bright yellow rain coat – before face-planting into its glass enclosure.
The lion, which is said to weigh about 181kg, hits the glass at full speed, colliding with the window face-first.
He paws fruitlessly at the glass, giving those watching a fright before slowly slinking away.
