You might be mauled to death if you can’t spot the mountain lion prowling in the nature scene in under 15 seconds

A MIND-BENDING brainteaser has people puzzled, but being unaware of the danger that lurks could be dangerous.

The optical illusion initially appears to be a serene outdoor scene, but a lion is hiding in plain sight.

Redditor Brad_the_chad_69 posted the ferocious feline to the social media platform.

"Find the cat," he said.

Once spotted, the creature was definitely too close for comfort for most.

"I would have died on that trail," one said.

HERE KITTY KITTY

Upon closer examination, a pair of predator eyes can be seen staring bake at the hiker.

The photo was taken during a hike in Cache Valley, Utah.

"I took [the photo]. I was trail running," the original poster said of the dangerous sighting.

"I took a photo of the trail and the sky [and] only saw the mountain lion while looking at the photo when I was back home.

"I about pooped my pants."

A pair of feline eyes can be seen staring back.

"The last thing you see before a mountain lion latches onto you," one Redditor said.

"That’s a large kitty cat," another added.

Everyone can see the trees & water but you have 20/20 vision if you spot the eagle hiding in plain sight in 20 seconds

"I was expecting a cute kitty cat, but then I saw those menacing cougar eyes in the brush," yet another said.

"That’s insane to think a mountain lion was that close, stay safe out there."

If the big cat wasn't enough, there are more optical illusions for lovers of brainteasers.

Another hidden cat is lounging around, and spotting it may take better vision than most.

This time, it's not quite as menacing as the feline on the hiking trail.
