Cat and heartworms

By Metro Creative
Dog owners may be familiar with heartworm medication used to address infection in canines, but no such option is available to treat heartworms in cats.
According to the American Heartworm Society, the medication veterinarians use to treat heartworms in dogs cannot be used in cats. The U.S. Food and Drug Administration (FDA) notes it has not approved any drugs to treat heartworms in cats, and the organization urges cat owners to emphasize prevention.
Several products that prevent feline heartworm infection in cats have been approved by the FDA, and all must be prescribed by a veterinarian. Prior to issuing such a prescription, a veterinarian may suggest testing the cat for heartworms, an approach the FDA recommends.
