Cat confused by optical illusion (it's like rotating snakes)

“Peter doesn't quite understand the famous 'Rotating snakes' illusion. It consists of a series of overlapping round wheels that appear to move like coiled snakes. This is actually very cool, because it seems to suggest that our cats see the same optical illusions as humans do, and so, the visual portions of their brains work like Humans' do.”
