There are a few very exciting things about this video:
2. Cat being adorable while looking at optical illusion
3. Cats can experience optical illusions?!
YouTube user rasmusab uploaded the video, "My cat can see the rotating snake illusion!" in order to start a discussion about this last, urgent question. He writes, "Show your cat the rotating snakes illusion, film it and let me know the result by filling in this form. If enough people do this we might be able to crowdsource some real evidence that cats can see visual illusions!"
Even if it's not groundbreaking, it's still pretty adorable.
