While several agents have been available for treatment of heartworm infection in dogs, no safe and effective adulticides exist for treatment of heartworm in the cat. Cats infected with heartworm may benefit from corticosteroid therapy to reduce clinical signs of pulmonary disease. Fortunately, four products are available for prevention of heartworm infection in cats (ivermectin, selamectin, moxidectin, milbemycin). Two products are given orally, and two are administered topically. Even cats diagnosed with heartworm infection can safely be given preventive treatment.
