We have just diagnosed your cat with asthma. This condition occurs when the bronchial tubes become filled with secretions and their walls are infiltrated by inflammatory cells. As a result, the bronchial passages narrow, restricting airflow into the lungs. Your cat may begin to experience respiratory difficulties, which may present as coughing, wheezing (especially on exhalation), open-mouth breathing, and increased respiratory effort with or without abdominal involvement. In severe cases, the mucous membranes may turn blue (cyanosis), which can be life-threatening.
Feline Asthma Treatment
The goal of treatment is to dilate the bronchi to improve airflow and reduce inflammation. To achieve this, we have prescribed the following medications:
- Prednisone (or prednisolone): A glucocorticoid anti-inflammatory that reduces bronchial inflammation. Possible side effects include increased thirst (polydipsia), appetite (polyphagia), and urination (polyuria). Prolonged use may lead to liver, kidney complications, or even diabetes.
- Fluticasone propionate (inhaled corticosteroid): Unlike oral prednisone, this aerosol corticosteroid acts directly on the lungs without systemic side effects. However, it takes 7 to 10 days to reach maximum effectiveness. Therefore, oral prednisone is typically recommended at the start of treatment.
- Salbutamol (bronchodilator): When used alongside fluticasone propionate, it should be administered first to dilate the bronchi and enhance the corticosteroid’s effect.
Using the AeroKat Inhalation System
To administer these medications in inhaler form, we recommend using the AeroKat system. This device includes a cat-sized mask, a reservoir chamber, and a nozzle for the inhaler.

Your cat may initially resist the mask. To ease administration, follow these steps:
- Assemble the three components of the AeroKat system.
- Place your cat comfortably on your lap or on a table, sitting behind them.
- Press the inhaler as prescribed so the medication fills the chamber.
- Don’t worry about leakage—the system’s valves prevent medication from escaping before inhalation.
- Gently place the mask over your cat’s muzzle and allow them to breathe for 7 to 10 seconds.
- After administering fluticasone propionate, rinse your cat’s mouth with clean water.
Feline Asthma Treatment Adjustments and Follow-Up
Depending on symptom severity, the treatment plan may need adjustments. It is essential to monitor your cat’s asthma signs and contact us if there are any changes in their condition. If you have questions or concerns, please call us.
Wishing your companion a speedy recovery!
