I don't know about paying rent, but I had one cat that would frequently go fetch his own dinner.......a nice skinned ready prepared fillet of white fish. To do this he had to cross a road, thread his way through a housing development, then another small road, an alleyway and cross the market square to the fish stall on the far side. He woulld choose his piece of fich and bring it home to eat. Oh and yes he would knock on the front door to be let in with it. THe one thing he forgot was tp pay for the fish.:lol:

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
