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 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.
