Pet odors can cost the seller thousands of dollars. Many times you don’t even realize there is an odor. To a non-pet person, the smell can be overwhelming and stop them at the door. Try to eliminate causes of odors such as litter boxes and cages. Lemon scented cleaning products are the best to help eliminate pet odors. Do not use air fresheners as they just tend to layer the smells. If at all possible, remove your pet from the home during the showing or open house.
