HEARTGARD® (ivermectin) is a monthly heartworm chewable given to your cat that prevents heartworm infection and helps treat and control hookworms. An infected mosquito that bites your cat can lead to potentially deadly heartworm disease in less than three months. That’s why it’s important to keep your cat on a monthly heartworm preventive year-round. Check with your veterinarian to make sure your cat has a current heartworm test result on file. Given monthly, HEARTGARD prevents heartworms from developing inside your cat and keeps them safe from future infections. Plus, it comes in a tasty, beef-flavored chewable tablet that makes it convenient to treat even the most finicky felines. All cats are at risk for heartworm disease, no matter where they live. Talk to your veterinarian about preventing heartworms in your cat with HEARTGARD.
