You could be mauled to death if you fail to spot the mountain lion prowling the natural landscape in less than 15 seconds

A mind-bending puzzle leaves people confused, but not knowing the danger that lurks can be dangerous.

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

Editor Brad_the_chad_69 posted the ferocious feline on 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,” said one.

HERE KITTY KITTY

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

The photo was taken while hiking in Cache Valley, Utah.

“I caught [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] I only saw the mountain lion while looking at the photo when I returned home.

“I almost pooped my pants.”

If you’re still having trouble locating the big cat, check the bottom left corner of the image.

A pair of feline eyes can be seen looking back.

“The last thing you see before a mountain lion clings to you,” said one Redditor.

“That’s a big kitten,” added another.

“I was expecting a cute kitten, but then I saw those menacing cougar eyes in the bushes,” said another.

“It’s crazy to think a mountain lion was that close, stay safe out there.”

MORE PUZZLES

If the big cat wasn’t enough, there are more optical illusions for puzzle lovers.

Another hiding cat is out there, and spotting it may require better eyesight than most.

This time, it’s not as threatening as the big cat on the trail.

The much smaller domestic cat is taking time off to rest and relax for a bit.

If you still can’t spot the kitten – it’s hanging under the Christmas tree.
