Note: It's an optical illusion, not an animated GIF. You can't print animated gifs on paper.
This is a video of a cat spazzing out on the optical illusion seen above. So now we know -- yes, cats CAN see optical illusions. And laser beams. Unfortunately mine can't seem to see where the litterbox ends, which explains why there's a turd on the floor in my bathroom. Well, at least I hope that explains why there's a turd on the floor in my bathroom.
Hit the jump for the video, it's awesome to see the kitty sitting there staring at the thing at the end.
Thanks to SLURM, whose cats don't care for optical illusions because they're too smart to be tricked. Man, I wish I had a smart cat. Dammit Shitty Bill, stop staring at the wall.
