This cat is the new 'blue dress.'
A simple black and white photo of a tabby cat appears to show it walking down a flight of stairs--but when you look again, the image seems to flip, making it look as if the cat is going up the stairs instead.
A post of the image by 9gag.com has received more than 3,600 comments and has spawned several YouTube videos attempting to explain the illusion.
Some insist the cat is going downstairs because of the way the edges of steps look. Others argue the picture was taken from the top of the steps looking down.
You may not get any work down today trying to figure this one out.
What do you think?
No one on the internet can figure out if this cat is going up or down these stairs http://t.co/6IReIPBugv pic.twitter.com/719OusHseJ

For goodness sake the cat is going upstairs. Is the collective hivemind of the Internet really going nuts over this?! #catgate
