Hooman mesmerized by cat mesmerized by optical illusion…


#3

Please tell me this has been posted before … because I just had one of the most intense déjà vu episodes in recent memory.


#4

Oh this has been all over Reddit for the last week at least. Never gets old though :heart_eyes_cat:

I’m not saying I don’t buy the premise here, but… I’m also pretty sure I’ve seen a cat do exactly the same thing to a completely blank sheet of white paper. They crazy.

Maybe you’re remembering the last time a similar video of a cat reacting to this optical illusion, back in March, 2013.

Bonus: Here’s the actual illusion for you to print out for your own kitties as well as a cursory explanation of why the illusion works, and a more detailed, scientific explanation.

Needs a catnip intensifier.

“This is more annoying than that damned ‘red dot’ that squiggles up and down the walls and across the floor, that I can never catch.”


#9

Now I know what is missing in my life. Floor tiles with this optical illusion on them. WANT!


#10

Thanks!

Gonna try this…


#11

Yay, thanks!


#12

Repost! This was posted years ago.


#13

It’s mesmerizations all the way down…

Also, tomorrow at game night, totally doing this to Vince’s cat, Persephone (I call her P Kitty).


#14

the cat is thinking, “MAKE IT STOP, MAKE IT STOP!”


#15

Remind me not to drink too much at your house.

“Everything is spinning!

Cats going ape is one thing, but watch out when an ape goes cat.


#18

There was a post quite some time ago which featured images like the moving-circles, only carefully-constructed in such a way that the illusion was lost and the circles would not spin no matter how much you looked at them. Alas, I cannot seem to find it at the moment. (Perhaps someone else recalls?)


#19

I think I remember seeing it, but I think it was in the comments thread of another optical illusion topic.

or drink more. with luck the two spin directions cancel each other out
