Heartgard Chewables are a flavored treatment for cats given once a month to prevent heartworms, and for the removal and control of adult and immature hookworms. Heartgard Chewables require a prescription from your veterinarian.
Cats (6 weeks of age or older and no weight requirement)
Heartgard prevents heartworm disease by eliminating the tissue stage of heartworm larvae for a month after infection.
It is important that you give your pet this preventative every month. If you miss than two monthly doses, we recommend calling your vet before continuing the medication. Also, note that side effects are rare at the recommended heartworm prevention dose. Side effects in cats include agitation, loss of appetite, staggering, dilated pupils, tremors, blindness and disorientation.
