Between the place where there is the food dish, and the place of the litter box, exists a miraculous openness, The Magic Portal. It doesn’t require any thumbs to operate, and it allows free passing to those in need. In the best of a times, a cat may travel unhindered up and down the stairs. At it’s worst, it is used as a political tool in the power struggle for territory and domination.

The view from the other side.
The humans like it because they don’t have to continually open and close the door for a cat, or leave the door ajar. In addition, The Magic Portal is a great source of entertainment for the humans, as the cat politics do not go unnoticed.
