In dogs, heartworm disease is a parasitic infestation that affects the heart and lungs. Adult heartworms grow up to 10 to 12 inches in length and populate the heart and pulmonary (lung) arteries. This population can cause lung disease and heart failure.
In cats, in addition to affecting the heart and lungs, adult heartworms can grow 5 to 8 inches in length. Cats are not the natural host of heartworms, and are capable of “fighting off” the infestation, but this does cause permanent damage to the cat.
