Bronchitis causes cats to cough. While your cat’s coughing may seem like a minor problem or a hairball, if the cough persists speak to a vet.

Bronchitis in cats is the inflammation of the airways within the lungs. It causes coughing in cats. This inflammation can be sudden, if due to an new infection, or it may be long-lasting (chronic). About 1% of the cat population is affected by chronic bronchitis.

What is bronchitis in cats?

Bronchitis is the inflammation of the lining of the tubes that carry air to and from the lungs, called bronchi and bronchioles.

There are many causes of bronchitis in cats.

Acute bronchitis has a sudden onset due to:

• Airway irritation by inhalation of foreign material

• Bacterial or viral infections

• Parasite infections, such as heartworm and lungworm

The main symptom of bronchitis is coughing. If the cough lasts more than two months, the bronchitis is referred to as chronic and includes two very similar diseases feline asthma and feline chronic bronchitis. Possible causes include:

• Inhalation of irritants like tobacco smoke, air pollutants

• Inhalation of allergens

• Inhalation of bacteria associated with dental disease

• Recurrent respiratory infections (bacteria, viruses, parasites, fungus).

Chronic bronchitis in cats develops slowly and can get worse over time.

How do vets diagnose bronchitis in cats?

• Detailed clinical history of the concerns you have and symptoms your cat shows

• Hands-on examination including listening to your cat’s heart and chest

• X-rays

• Blood and urine tests

Your vets might also recommend:

• Faecal test

• Heartworm blood test

• Lower airway evaluation and sampling: This involves passing a bronchoscope (a small camera on a flexible tube) through the mouth and down the throat to visually examine the lower airway while your cat is under anaesthesia. Samples of tissue and airway secretions may be collected during this procedure for additional testing.

• Steroids by mouth or inhalation
