Answer

Answer

Because of its small size, this allergen is predominantly an airborne, indoor type. Avoidance involves removing animals from the home (or at least from the bedroom), using dense filtering material over heating and cooling duct vents, and washing cats and dogs as often as twice weekly. Antigen may remain in a home for 6 months or more after cats are removed from the home, and cat antigen may be found in homes and offices where cats were never present, highlighting the importance of frequent cleaning.
