When I think of reasons to keep certain rooms off limits to pets, the flooring type makes a huge difference since carpet's a pet hair magnet that hangs on tightly (unless you have one of these awesome vacuums). Likewise, it's much trickier to get accident evidence out of carpet than it is from hard, solid surfaces. Since most bathrooms and kitchens have tile, stone, or linoleum, excluding those rooms, what kind of covering covers most of your floors at home?
