Guess where is this cat going – up or down?

Funny optical illusion: at first you can not say, whether this cat going up or down

So, what’s your guess, up or down?

Yes, you are right! This cat is going down the stairs. First, look at the contour of the steps (none would make such projections on the edges), and secondly, pay attention to the shadow the cat casts, as well as the position of his feet and the tail sticking up. Now, I think, you have no doubt.
