What does this mean?

Your cat has tested positive for heartworms, which means there is at least one adult female heartworm present in the blood vessels between the heart and lungs. In cats, even one or two heartworms can cause serious health problems.

​

Unlike dogs, there is no approved treatment that completely cures heartworms in cats. However, there are important steps that can help manage the disease and improve your cat’s quality of life.

​

Recommended Treatment and Care:

1. Start your cat on monthly heartworm prevention for life.
   Many heartworm preventatives also protect against fleas and other parasites.

2. Start a 30-day course of antibiotics.
   Your veterinarian may prescribe oral liquid doxycycline or minocycline once daily for 30 days.

3. Monitor your cat for symptoms.
   Signs of feline heartworm disease may include:
   • Vomiting
   • Coughing
   • Difficulty breathing
   • Low energy
   • Decreased appetite

4. Prednisolone may be prescribed if your cat develops symptoms.
   This medication helps reduce inflammation in the lungs and breathing passages. The dosage is usually started higher and slowly reduced to the lowest amount needed to control symptoms.

5. Emergency medication may be sent home.
   You may receive a syringe with an emergency glucocorticoid medication to use only if your cat has a severe breathing crisis at home. This medication is intended to help stabilize your cat while you immediately transport them to a full-service veterinary clinic.

6. Schedule a follow-up appointment with PAAC.
   Please contact PAAC to schedule an appointment with one of our veterinarians to discuss your cat’s condition, treatment plan, and long-term care.

Important:
Cats with heartworms can decline quickly if breathing problems occur. If your cat is struggling to breathe, seek emergency veterinary care immediately.
