You’d think that an indoor cat would be protected from all the dangers of the great outdoors. Unfortunately, staying in the house doesn’t guarantee your feline is safe; ticks, fleas, mites, and heartworms still pose a significant risk, even indoors.

The biggest threat to an indoor cat is heartworms, which are spread by a mosquito that carries heartworm larvae. Only one mosquito bite can cause your cat to be infected with heartworms. The symptoms of heartworm infestation in cats are similar to asthma or pneumonia, and the disease is hard to detect and diagnose. Both of these factors mean that heartworms often go undetected for a long period of time.

A cat with heartworms could easily have 14 inch heartworms in their heart and arteries. Dead or alive, heartworms can kill your cat. Even after treatment, dead heartworms put a horrible strain a cat’s system. The truth is sobering; heartworms are often fatal.

While they aren’t usually life threatening, ticks, fleas, and mites get into your home, too. They sometimes hitch a ride on your clothing or on mice or squirrels that may be hiding in your attic. And sometimes, they just by hop through the open door or window.

The good news is that there’s an easy way to protect all cats from parasites: Revolution®. Each month, apply Revolution® to the skin between your cat’s shoulder blades, and keep your cat safe at home.
