Feline Fungal Lung Infections

Fungal infections that directly affect the lung can become life-threatening if not treated immediately. In cats, fungal infections are relatively rare and are often treated with anti-fungal medications.

  1. What is a Fungal Infection?

    • Fungal infections are caused by actual fungi, or plant-like organisms, growing within a host, such as a cat. Some fungi is beneficial for foods, composting and various other necessities. However, some fungi can cause infections and be dangerous to the health of humans and pets.

    Coccidioidomycosis

    • Commonly known as "Valley Fever," coccidioidomycosis is a fungal infection that is relatively common in cats in the Southwestern portion of the United States. Fortunately, this disease is relatively easy to treat with the use of anti-fungal medications.

    Histoplasmosis

    • Histoplasmosis occurs when the fungus enters the cat's body through the lungs. It can cause a variety of issues with the respiratory system and the intestinal tract. Most animals will recover without any medications, but some cats may require anti-fungal medications to treat the fungal infection.

    Pythiosis

    • Pythiosis is an uncommon fungal infection that occurs very rarely in cats. Pythiosis is often fatal and occurs when the animal drinks from stagnant water, particularly waters found in the southern portion of the United States.

    Aspergillosis

    • While aspergillosis does not directly affect the lungs, it is a fungus that affects portions of the respiratory system. Aspergillosis is inhaled and causes an infection within the nose and the nasal passage.
