Is this cat going up or down stairs?

New optical illusion duping viewers


After the rabid, and some might say inexplicable, Internet takeover of #TheDress, a new optical illusion is duping viewers.

The image, initially posted on social networking site Imgur, shows a cat walking on stairs with the caption "This cat looks like its (sic) going both up and down the stairs".

The photo has gained some 28,000 Imgur views and counting.

What do you think, where is the cat going?
