Cat image sparks social media buzz: Is it walking up or down the stairs?

Hot on the heels of the “dressgate” social media storm another intriguing image is generating massive Internet buzz.

The image of a cat, which is either walking up or down a set of stairs (depending on how you look at it) appeared anonymously on the Imgur website 6 days ago, where it has already racked up more than 41,000 views.

Commenters on the website are divided about the image, which has sparked debate ranging from the physiology of cats to the architecture of the stairs in the image.

The debate about the image has also been raging on Twitter, via the hashtag #catstairs.
