Cats with severe manifestations of feline heartworm disease may
require additional supportive therapy, and may benefit from intravenous fluids,
oxygen therapy, cage confinement, bronchodilators (which expand the air passages of the lungs), cardiovascular drugs, antibiotics and nursing care.
Cats with more serious symptoms are usually hospitalized and may
require additional medications, such as bronchodilators, IV fluids,
oxygen, and antibiotics.
