Are cats fooled by optical illusions?

The Rotating Snake Illusion is a fun image that makes your brain perceive motion where no motion actually exists. Psychologists understand the factors that make an illusion like this work (and work better) — for instance, breaking up and staggering the colored lines that radiate from the center of the circle creates a much stronger sensation of movement. But they don't know exactly why it works yet, according to Japanese psychologists Akiyoshi Kitaoka and Hiroshi Ashida.

And that brings us to this kitten video.

YouTube user Rasmus posted a video that he thinks might show his cat being tricked by the same sense of motion that catches the eyes of humans who look at The Rotating Snake Illusion. On the other hand, this just might be a cute video of a kitten attacking a piece of paper — which is known to happen.

So here's the challenge: Try it on your cat. You can print it off here. Then, report back here and/or post video responses to YouTube. Let's gather some data!

This is not exactly the soundest experimental methodology ever, but it sure would be interesting to see what happens.
