Heartworm is a very dangerous medical condition caused by parasitic worms that enter the cat's bloodstream through infected foods, fleas, or ticks. The best treatment for heartworm is prevention, and this is what prescription-grade heartworm treatments provide. Heartworm medications are often combined with flea and tick medications for a more comprehensive treatment plan, but they can also be sold as a separate product. It is important that cat owners remain vigilant when administering heartworm medication, and to look for any signs of a possible heartworm infestation in the cat's feces. An actual case of heartworm often requires more aggressive treatment from a veterinarian.
