Secrets To Protecting Your Bengal Cat From Heartworm


Heartworm is typically considered to be dog disease, but we cats can contract it too. It’s a disease that is much more difficult to assess in us felines. Signs of heartworm can either be very subtle or very dramatic, there’s no in-between.

Cats affected by heartworm may have difficulty walking, experience seizures or fainting, or suffer fluid accumulation in the chest. In some cases, the first sign may even be sudden collapse or death.

Since there are no approved treatments for heartworms in cats, the only way to fight against the disease is through prevention. There are several monthly preventatives available on the market that your veterinarian can prescribe for your cat. It’s also important to maintain regular checkups to make sure they’re healthy and protected.


Heartworm disease is a serious and potentially life threatening disease caused by foot-long worms that once enters the body, will live in the heart, lungs and other associated blood vessels of affected pets. Damage to these organs will cause heart failure, severe lung disease and compromised organ function.

Carriers of the disease include other mammals such as foxes, coyotes and wolves, which live in close proximity to many urban areas.


  • Mild to severe coughing
  • Loss of appetite
  • Weight loss despite regular eating habits
  • Fatigue
  • Difficulty breathing (gasping for air)


Mosquitoes play an important role in the life cycle of the heartworm. Adult female heartworms living in infected mammals such as dogs, foxes or coyotes, will produce baby worms that will circulate in their bloodstream.

When a mosquito bites and takes blood from these infected animals, it also picks up these baby worms, which eventually develop into infective larvae. Then, when the infected mosquito bites another mammal, the larvae is deposited onto the surface of the animal’s skin and enters its new host through the bite wound left by the mosquito.

Once these larvae mature into worms, they can survive for 2-3 years inside a cat. That means the number of worms can easily increase for every mosquito season that passes.


Since the heartworm medications used for dogs can’t be used for cats, the only way to prevent them from getting heartworms is through preventative measures.

You can use monthly preventatives and schedule regular heartworm exams for your cat to ensure that they’re protected from the disease all year round.

Keeping your cat indoors can also help, but it is not fool proof, make sure to vaccinate your cat for heartworm.

Here are some monthly preventatives you can use (all of these preventative medications require a prescription from a veterinarian):
