Hello...I have a question regarding heartworms. Potter is at the vets office right now for his comprehensive exam, they asked me if I wanted to purchase heartworm medicine...I said yes I need some for both dogs they just had their last pills. They said what about potter?

To be honest I never knew cats could get heartworms. I didn't vacinnate my rb gigi against everything because she was indoors....potter does go outside...are heartworms really a risk to cats?

Any info would be appreciated....
