I personally have built stairs before and no one in there right mind is going to put a lip like that on the top of a stair...on the side yes but on the top no just no

 

The slabs on top of the stairs wouldn't be going up and down, if they did they would make those stairs very uncomfortable to walk on. And what would be the point?

 

I would think down because of the slabs on the stairs.

 

Up

 

You know, when I look at this picture, I can see both the cat going up and down, but when you think about it logically... The cat is going up because of the way the end of each stair is up a little.

 

What if they aren't stairs? Maybe it's just a flat hallway.

 

As this is a picture I will be moving it to the Pictures forum.

Thread Moved

 

Actually when you look at the end, you see it as a flat ramp coming up with the slabs coming up.

 

Its going up
