Did you know that Orange Tabby cats can contract heartworms in similar ways to dogs? Make sure that your vet tests your Orange Tabby Cat for heartworms at annual exams. You should also double check to make sure your cat is on a monthly heartworm prevention program as well. In general, the disease can be serious if not treated properly. Heartworm disease is caused by a large worm or heartworm that can invade the heart, lungs and blood vessels of your Orange Tabby Cat. Unlike dogs, your cat may only have one to three worms present in her body. If cats do have heartworms they are most likely to have no adult worms. However, the worms can still cause damage to your cat’s health by causing a heartworm associated respiratory disease also known as HARD. Medication used to treat heartworms in dogs is not effective in cats. Talk to your veterinarian Frisco, TX for more information or click here.
