If your cat has an enlarged heart, it is important to monitor your cat for any trouble breathing, exercise intolerance, weight loss, decreased appetite and the other symptoms listed above under “Signs of an Enlarged Heart”.  If you see any changes in your cat, you should see your veterinarian immediately.

Most causes of an enlarged heart cannot be prevented other than heartworm disease. Feline heartworm disease can be prevented with monthly prevention medications such as Revolution®. Please discuss heartworm prevention recommendations with your veterinarian.
