Heartworms are nine to eleven-inch long worms that live in the heart of dogs and cats. Only one or two heartworms in a cat is enough to cause a fatal outcome and it only takes one infected mosquito to transmit the disease.
Although heartworms are more common in dogs and outdoor cats, indoor cats can also be infected. As many as 25% of heartworm positive cats lived indoors exclusively. Heartworm disease is difficult to diagnose in cats and, unlike dogs, there is no treatment. Cats that seem to be doing well may die suddenly.
There are no specific clinical signs for diagnosing feline heartworm disease. If your cat is showing any symptoms of coughing, vomiting, shortness of breath, weight loss and/or lethargy, please have your cat examined by your veterinarian as soon as possible.
Prevention Is Safe and Easy by keeping your cats on monthly heartworm prevention. These same products help prevent fleas, ticks, hookworms, roundworms and ear mites.
