Fine, fine. Cats can see a thing which is a trick of perception making you see something that doesn’t really exist but that totally isn’t an optical illusion. Just please stop explaining it to me. 
harpy princess @InvaderXan I bet its most creatures that hunt

I'm always curious about how similarly other animals see the world. Things like this are all about how our brains perceive and process optical information. Cats are quite close to us, evolutionarily speaking, but would more distant hunting animals also see this?
Mantis shrimp, for instance, will chase laser pointers the way cats do, but I wonder if they'd also see this illusion.
@InvaderXan Well yeah.
How are they gonna catch those balls if they can't see them move?
@InvaderXan the camera sees it too, so I don't think this is related to how the eyes of any specific animal work
@InvaderXan
I get what you meant, and to be fair, I'd have called it an optical illusion too
