Looking for a cheap and easy way to mess with your cat? Well, I can't hear your response, but since you own a cat, I'm going to assume the answer is yes.

Swedish YouTuber rasmusab recently printed out a bunch of optical illusions and found that one in particular — Professor Akiyoshi Kitaoka's snake illusion — had a rather curious effect on his cat.

The interest has since worn off — cats, am I right? — but it was funny while it lasted.
