Heartworm Infection in Cats

Do cats really get heartworms?
Though heartworm infections are more common in dogs, cats can get heartworms.  While dogs usually develop a large number of heartworms that can eventually cause heart failure if untreated, cats typically harbor very few adult worms.  However, when the cat's immune system starts attacking the heartworms, it can cause a deadly anaphylactic reaction that is difficult to treat.  Here, in the state of Indiana, heartworms are a big problem.

Heartworm Life Cycle
Mosquitoes become carriers of heartworm larvae when they feed on an infected animal.  When the infected mosquito bites a cat, the larvae enter the cat's system.  Cats are not a natural host of heartworm larvae and the life cycle is less likely to be completed.  Worms that do survive in the cat's system can cause an immune reaction that could create severe health problems.

There is a great computer animated video that has been put together by the American Heartworm Society that shows the life cycle of the heartworm, and how it effects cats.

Signs & Symptoms
Below is a list of some signs & symptoms that could be associated with feline heartworm infection:
  • Persistant cough
  • Breathing difficulty
  • Depression
  • Loss of Appetite
  • Weight Loss
  • Vomiting
  • Lethargy
  • Blindness
  • Syncope/fainting
  • Tachycardia/fast heart rate
Health problems that can affect your cat, should they become infected with heartworms:
  • Damage to heart & lungs
  • Damage to pulmonary (lung) vessels
  • Obstruction of blood flow
  • Difficulty breathing
  • Heart & lung failure
  • Kidney & liver damage
  • Sudden death

It can be difficult to diagnose feline heartworm infections.  Radiographs (Xrays) and bloodwork will be done when a cat is symptomatic. Since cats are naturally stoic creatures, it may be hard to tell that your cat is sick until the disease has become a major problem.  If  you notice your cat displaying any signs of respiratory distress, such as coughing, panting, open-mouth breathing or wheezing, it's a good idea to take your cat to the veterinarian immediately.

This deadly disease is much easier to prevent than it is to treat.  There are currently no products approved for cats, in the US, for the treatment of adult heartworm infections, so prevention is key.  Even indoor cats can be bitten by an infected mosquito, as they can easily enter a home from an open door or window, and it only takes one bite from an infected mosquito to cause infection.  We recommend that your cat be seen by a veterinarian yearly, and be kept on a regular monthly preventative, such as Advantage Multi or Revolution.

Dr. Campbell says Good-bye. :(

Almost 13 years ago, while still in high school, I began my employment at Animal Hospital of Avon and Rockville Road Animal Hospital.  My first day on the job, a fresh-faced assistant with zero experience, I was only trusted to follow Dr. Richards around to erase the scuffs his shoes made on the newly waxed floor and clean out the freezer of a forgotten exploded Pepsi can…and I loved every minute of it.  I was so excited to be around cats and dogs on a daily basis and work with a group of people that were more than a team, they were a family.  Slowly my responsibilities progressed and the skills I developed with the experiences I had there became the basis of my application to Purdue’s School of Veterinary Medicine.  Throughout my time at Purdue, I would return on breaks and vacations to squeeze in as much time as I could at my second home.  As fate had it, when the time came to graduate from school, they were in need of a full-time veterinarian!  What better place to start out than in the comfort of your own home! 
As you all know, working at an animal clinic is one of high stress, emotion, excitement and sadness.  Adjusting to these ups and downs was difficult but bearable when surrounded by such a fantastic staff and clientele.  It is very rare to find a group of people like these who genuinely care for all of their clients and patients.   My time here has been extraordinary, but unfortunately life has taken me in a new direction.        
I’m saddened to announce officially that by the end of May I will be no longer a part of the fantastic teams of Rockville Road Animal Hospital and Animal Hospital of Avon.  I cannot thank my staff, colleagues, and bosses enough for all that you have done to support me and contribute deeply to the type of veterinarian I am today and strive to become.  We will forever be family.

With Love,

Rachael  (Dr. Campbell)
