A few years ago when I lived up North I took care of the yard for a woman that lived by the river in an old one story house.
Some time before her pet rats had escaped from their cages and at the end of her house she would feed them, there were dozens (maybe hundreds) of them after a while.
Her house has "paths" in it, made from the cardboard boxes and misc junk she had around. There was one place on a couch to sit.
When I had to go to the kitchen to fix the stove I had to maneuver the trails to get to the stove.
One day her house burned down completely, rats and all.
So she got a trailer and more stuff. And more boxes. In a matter of weeks she had the trailer full of junk and boxes.
Last I heard (last year) she hasn't suffocated yet.
Oh, and where she worked she collected lots of dollar bills. She would spend her wait time ironing them.
