Cat Pregnancy Calculator And Timeline

Aspergillosis is a fungal infection that affects cats. It is caused by the fungus Aspergillus, which is commonly found in the environment, particularly in soil, hay, and feed. Cats can become infected by inhaling the spores of the fungus or by ingesting contaminated food or water.

Symptoms Of Aspergillosis In Cats

Symptoms of aspergillosis in cats can vary depending on the type of infection and the location of the fungus in the body. Common symptoms include coughing, sneezing, nasal discharge, difficulty breathing, and loss of appetite. In some cases, the fungus can also invade the lungs, causing inflammation and scarring, which can lead to lung abscesses or even lung collapse.

In severe cases, the fungus can spread to other parts of the body, such as the eyes, skin, and bones, and can cause additional symptoms, such as eye discharge, skin lesions, and lameness.

Causes Of Aspergillosis In Cats

The primary cause of aspergillosis in cats is inhaling the spores of the Aspergillus fungus. Cats with respiratory issues, such as feline asthma or chronic bronchitis, are more susceptible to infection.

Also, cats with compromised immune systems, such as those undergoing chemotherapy or those with feline immunodeficiency virus (FIV), are also at a higher risk of contracting aspergillosis.

Additionally, cats living in poorly ventilated environments, or exposed to mold or high levels of dust, are also at a higher risk for contracting the disease.

Treatment For Aspergillosis In Cats

Treatment options for aspergillosis in cats will depend on the severity of the infection.

In mild cases, treatment may involve administering antifungal medication and providing supportive care, such as oxygen therapy or nebulization, which is usually given for a period of several weeks to several months, depending on the severity of the infection. Antibiotics may also be prescribed to help control secondary bacterial infections.

In more severe cases, surgery may be necessary to remove the fungus and damaged tissue.

Diagnosing Aspergillosis In Cats

It is important to see a veterinarian as soon as possible if you suspect your cat may have aspergillosis. A veterinarian can diagnose the infection through a variety of diagnostic tests, such as a fungal culture, X-ray, bronchoscopy, or biopsy.

Cat Breeds Affected By Aspergillosis

All breeds of cats are susceptible to aspergillosis, but cats with respiratory issues, such as feline asthma or chronic bronchitis, and cats with compromised immune systems are at a higher risk of contracting the infection.

Prevention Of Aspergillosis In Cats

It’s also important to provide a clean and well-ventilated living space to reduce exposure to potential sources of fungal spores.

Food Suggestions For Aspergillosis In Cats

In terms of food, there is no specific food that can help a cat recover from aspergillosis. However, providing a well-balanced and nutritious diet can help support your cat’s overall health and immune system.


In conclusion, Aspergillosis is a fungal infection that affects cats, caused by the fungus Aspergillus. It is a serious condition and early detection and treatment are crucial for the best outcome for your cat. If your cat is showing signs of respiratory distress or other symptoms of aspergillosis, it is important to seek veterinary care immediately. With proper treatment and care, many cats with aspergillosis can recover and return to a normal, healthy life.
