To most, the first thing they will see in this image is a laughing dog.

How long does it take you to spot the kitty?

If you can find the feline in under four seconds you may have a high IQ.

Regular practice of solving illusions such as these can help improve brain function.

In addition to this, they also help test your patience while giving you time out of a busy day.

Illusions “test your critical thinking, problem-solving, and application of both qualitative and quantitative methodology abilities,” according to illusion experts at Jagran Josh.

Such puzzles “illustrate how the brain organizes and interprets visual data, showing that perception is more complex than simply looking in the mirror,” they added.

If you are struggling to find the cat, some players find that a simple eye trick can reveal all.

Try squinting your eyes at the image and see if the kitty is revealed.

If you want an extra clue focus on the dog’s nose and teeth.
