The Truth About the Disease

Heartworm disease is a potentially life-threatening illness caused by parasitic worms that live in the heart, lungs, and blood vessels of infected animals. While dogs are the most commonly affected, cats and other mammals can also become infected.

For Cats

  • Sudden Vomiting or Gagging
  • Rapid, Shallow, or Difficult Breathing
  • Extreme Lethargy and Weight Loss

Treatment Can Be Challenging

For infected dogs, treatment often involves multiple injections, strict activity restriction, and careful monitoring during recovery. The process can take several weeks and carries potential risks.

Unfortunately, there is currently no approved treatment that eliminates adult heartworms in cats, making prevention especially important for feline companions.
