Can prevention be used to control heartworm in a cat or to cure it? - Animal Hospital of Statesville
It can prevent it. I don't think the research has been done out there yet to see if chronic prevention eventually treats or kills the heartworm. Having an adult heartworm die is often fatal to the cat, so we can’t let anything reach adulthood by prevention.
