The largest and least expensive home I could find to give my guinea pig more space.  As suspected, the canvas bottom is difficult to clean and my pig has been chewing up the velcro/canvas along the divider (where it's easily accessible to her).  "Created" a perfect sized table at my local build-it-yourself style home furnishings store to keep the habitat off the floor and plan to purchase coroplast sheeting to aid in the cleaning and chewing problems (will also be less obtrusive to my color scheme than the green-blue canvas).
