You have 20/20 vision if you can spot the 4 cats hidden among the tigers in less than 20 seconds

IF you want to challenge your visual acuity on an epic scale, now’s your chance.

You have just 20 seconds to spot the four cats hidden among the tigers in this optical illusion.

A successful mission completed in the allotted time scale means you have 20/20 vision.

But a friendly word of warning: this is no easy task.

You really do have your work cut out.

There is likely to be a lot of head-scratching and expressions of frustration with this optical illusion.

If you succeed, then congratulations — it means you have excellent vision and attention to detail.

But if you fail, don’t be too hard on yourself.

This is a tricky challenge and the artist responsible for the image is not in the business of making it easy for you.

Gergely Dudas Dudolf () has a track record of producing similar scenes.

Based in Budapest, Hungary, he has created dozens of bewilderingly frustrating .

He has enormous fun at the expense of gamers creating these colorful, humorous images.

These furtive felines do what they do best and blend seamlessly into the background.

The tigers are no help, they are looking after their own – albeit domesticated – kind.

If you have failed to find the camouflaged cats, we have circled their location in red in the picture below.

Better luck next time.
