Can prevention be used to clear a heartworm infection? - The Drake Center
No, it differs. Prevention entails preventing the disease. It's not going to treat the cat if they already have heartworms. Like I said before, there is no treatment for heartworm in cats. There are treatments for the side effects that they cause, but there's no treatment to kill the actual worm.
