Feline Asthma: Managing a Chronic Respiratory Condition

Feline asthma is a common, chronic lower airway disease in cats causing recurrent episodes of bronchoconstriction and respiratory distress. Long-term management significantly improves quality of life and reduces emergency crises.

Key Facts

Feline asthma affects approximately 1-5% of cats and can occur at any age, though young to middle-aged cats are most commonly diagnosed
The condition results from allergic airway inflammation causing bronchoconstriction, mucus production, and airway remodelling
Clinical signs range from mild chronic coughing to acute, severe respiratory distress requiring emergency intervention
Siamese and related breeds appear predisposed to feline asthma
Diagnosis uses radiography, bronchoalveolar lavage cytology, and response to treatment — differentiating from other respiratory diseases is important
Management involves corticosteroids (inhaled or systemic) and bronchodilators (salbutamol/albuterol for acute crises)
Aerokat inhalers allow cats to receive inhaled medications without the systemic side effects of oral steroids — a significant welfare advance

Welfare Considerations

Feline asthma causes distress that ranges from chronic low-grade discomfort (persistent cough, reduced exercise tolerance, increased respiratory effort) to acute, life-threatening bronchospasm. Cats in acute asthmatic crisis adopt the characteristic open-mouthed, extended-neck breathing posture — a sign of extreme respiratory distress. Without treatment, episodes can be rapidly fatal. Chronic, undertreated asthma causes progressive airway remodelling that worsens baseline function over years. The welfare benefit of inhaled corticosteroid therapy is substantial: it controls airway inflammation with less systemic steroid burden than oral prednisolone, reducing the side effects of weight gain, diabetes risk, and immune suppression while maintaining respiratory control. Trigger identification and avoidance (dust, smoke, aerosols, litter dust) reduces episode frequency.

What You Can Do

Seek veterinary diagnosis if your cat shows persistent coughing, wheezing, or any episode of open-mouthed breathing
Ask your vet about inhaled corticosteroid therapy using an Aerokat spacer — this is the gold-standard long-term management
Keep a salbutamol/albuterol inhaler available for acute crisis management — discuss emergency protocols with your vet
Identify and eliminate potential asthma triggers: switch to low-dust litter, avoid aerosol sprays and cigarette smoke
Monitor resting respiratory rate at home — sustained rates above 40 per minute indicate worsening control
