Understanding Feline Asthma: A Guide for Cat Owners

Did you know that cats can suffer from asthma just like humans? Feline asthma is a chronic inflammatory condition of the lower airways in the lungs, and it can significantly affect your cat’s comfort and quality of life. At Lonsdale Place Veterinary Clinic in North Vancouver, we believe in empowering pet owners with knowledge to help keep their pets healthy and breathing easy. North Vancouver Vet

What Is Feline Asthma?

Feline asthma, also known as feline allergic bronchitis or feline lower airway disease, is a respiratory condition that causes inflammation and narrowing of the small airways in the lungs. This leads to difficulty breathing, coughing, and wheezing. It’s estimated that around 1–5% of cats are affected, with young to middle-aged cats being the most commonly diagnosed.

What Causes Asthma in Cats?

Asthma in cats is usually triggered by allergens or irritants that cause an exaggerated immune response. Common triggers include:

• Dust and dust mites

• Cigarette smoke

• Aerosol sprays or strong cleaning products

• Pollen and mold spores

• Cat litter dust (especially clay-based litters)

• Cold or dry air

Here in North Vancouver, seasonal changes, indoor heating in the winter, wildfire smoke, and damp conditions can all contribute to flare-ups in sensitive cats.

Signs of Feline Asthma

Asthma symptoms in cats can range from mild to life-threatening. Watch for these common signs:

• Frequent or chronic coughing (may sound like gagging or hacking)

• Wheezing or noisy breathing

• Open-mouth breathing

• Increased effort when breathing, especially on exhale

• Lethargy or reluctance to exercise

• Blue-tinged gums or tongue (in severe cases)

If your cat is showing any signs of respiratory distress, it’s critical to seek veterinary care immediately.

How Is It Diagnosed?

Diagnosing feline asthma involves a combination of:

• Physical examination

• Chest X-rays

• Bloodwork and fecal tests (to rule out other conditions such as heartworm or parasites)

• Airway sampling (in some cases)

Your vet will use these tools to rule out other causes of coughing and assess the degree of airway inflammation.

How Is Feline Asthma Treated?

While there is no cure for feline asthma, it can be managed effectively. Treatment typically includes:

• Corticosteroids – These anti-inflammatory medications reduce airway swelling and help improve breathing.

• Bronchodilators – These help open the airways during acute flare-ups.

• Inhalers – Yes, cats can use inhalers! Special feline inhalation chambers (like the AeroKat®) are designed to deliver medications directly to the lungs with minimal stress.

• Avoiding triggers – Reducing exposure to known allergens in your home environment is essential for long-term control.
