Have you tried to show a visual illusion such as the rotating snakes illusion (
http://www.ritsumei.ac.jp/~akitaoka/index-e.html) to your cat? What reaction did you get? Did you even film it? Please let me know how your cat reacted by filling in this form. Information you (and hopefully many others) enter in this form will be publicly available in some form at a later stage. If you want to get notified when this happens please leave your e-mail, which I will only use to send you this notification.
If you have any questions about this survey please mail me at:
