How to mess with a cat, chapter 374

Cats vs. the rotating snake version of the peripheral drift illusion. One is merely mesmerized but another takes a more aggressive approach. These cats have other priorities. Is this cat dumb, or is he too smart to participate in his human’s science experiments? Does the illusion have the same effect on dogs? Apparently some prefer to be more interactive.
