Someone printed the mirage 'rotating snakes' on a sheet of paper and put it in front of his cat. You might think that the illusion works only on humans, but watching the reaction of the cat jumps onto the paper, one can understand that it is not so.

'Rotating snakes' is an optical illusion that was designed by Akiyoshi Kitaoka Japanese. It is a still image that consists of twelve cycles, but when someone is looking at the picture you can see the circles rotate around themselves. Seeing the circles to move, the cat tries to touch them with her foot.
