"My partner and I created a rental-friendly (i.e. no holes in walls) cat run using 2 Ikea Expedit shelving units." The shelves form the base for the run, which is made from a 2.8m x 0.4m chipboard. The run is carpeted for kitty to sink its claws into. A little ledge was also added to the side of the shelving unit, so that kitty can get up there.
