A picture of a cat on a set of stairs has quickly gone viral as many try to figure out whether or not the feline is going up or down.
The viral illusion was first posted by 9gag.com and started to spread across the Internet as people debated over whether or not the cat pictured was climbing up or down a flight of stairs.
“For goodness sake the cat is going upstairs,” tweeted Jonathan Chang. “Is the collective hivemind of the Internet really going nuts over this?!”
“The cat is going up, the tail is used to balance the body of the cat and in this case the tail is elevated upwards so that when the cat uses its rear legs to push up it pushes parallel to the line on which gravity is working on the tail to stabilize itself,” one commenter argued.
“Look at the cat’s tail — it’s facing upwards, or the opposite of the direction it’s moving in. If the cat were to go up the stairs, it’s tail would point downwards,” another commenter noted.
