Conventional asthma medications are effective for a cat allergy. Allergy shots (immunotherapy) generally work. Treatment with anti-IgE is likely to be effective. Work is in progress on oral and inhaled immunotherapy. Some doctors believe that weekly bathing of the cat reduces exposure to allergens enough to decrease symptoms. There are also cleaning products available from allergy supply houses that help to break down cat allergen that may be trapped in carpeting or furniture.
