If you look at certain optical illusions, it appears that they’re moving even though the images are static and printed on paper. Sometimes these optical illusions can be annoying and sometimes they can be entertaining, but generally most people don’t look at an optical illusion and lose their mind.
Then again, most people aren’t cats. One cat looked at an optical illusion and got so infuriated that he attacked it. Perhaps the cat didn’t understand why the image seemed to move before its eyes but whatever the reason, this proves that optical illusions are no match for a cat with a mind of its own and the physical means to carry out its will at any time.
