This cat condo fits on the back of a door, creating extra space in a small area. The Over the Door Cat Condo by Hammacher Schlemmer is ideal for active felines who enjoy climbing, pouncing and lounging, not to mention fitting into and around furniture. It therefore has a dual function as an entertainment system for curious kitties.
The space saver has five compartments stretching over 5 feet and can accommodate up to five animals at a time. There are seven holes for easy access on the fronts and side. The product is made out of durable 600-denier polyester fabric which can withstand lots of scratching and climbing.
This is ideal if you have multiple cats in an apartment, especially curious cats with lots of energy.
