This is a cute optical illusion which is doing rounds on optical illusion. In this picture, there are three cats hidden among the group of tigers.The image shared by an Instagram user "thedudolf" has seen a good participation among social media users."Found all took time to find the 4th orange cat," one user wrote; "Found them all! So cute and tricky!," wrote another."Found 'em all less than 1 minute 3 orange cats, 1 white cat," another user has dropped the biggest hint on the optical illusion.

"This might be the easiest so far. I found them within 30 seconds. Thani you for creating and sharing!," wrote another.

The picture has a group of tigers with their characteristic stripes and since cats have similar stripes it is difficult to tell them apart from the bigger cats.

Optical illusions as such test the general knowledge of the user. It would assess the user's knowledge about cats and their behaviour.
