When you bring home a Fido or a Fluffy, you take the good with the bad (good: loyalty and affection; bad: eau de fur ball). Before guests arrive, nix any odors with plain old baking soda. Liberally sprinkle it over upholstered furniture and rugs and leave overnight to absorb smells before vacuuming. Use the upholstery and crevice tools on the cushions to get deep into nooks and crannies. If you're cleaning a litter box, put a layer of baking soda in the bottom before refilling with litter for extra defense against stink.
