You can eliminate pet odors in your house by cleaning up any accidents right away and disposing of excrement in a timely manner. Clean out litter boxes regularly, and remove any droppings from the yard right away so that nothing gets tracked inside.
Keep an enzyme product in the house to neutralize any pet messes. Regular cleaners tend to mask the odor without actually eliminating it. Keep other supplies like scrubbers, towels, baby wipes and bleach to get rid of stains and smells. Invest in a good quality vacuum and consider purchasing a carpet cleaning machine. Launder pet bedding often, and give pets regular baths with soap that is designed specifically for their species. Remember that using strongly-scented chemicals can be unpleasant, and in some cases harmful, to pets.
Keep your home picked up, and take time to perform regular deep cleanings. Have long-haired animals groomed regularly. Sprinkling baking soda on a pet mess can help to absorb liquid and odor. Consider putting some HEPA air filtration devices in your home and change the filters in them often. Remember also to change your furnace filter often. Wash pet dishes and clean pet toys often, throwing them away when they become overly soiled. Open windows often and keep good air flow in your home.
