Bronchiectasis in Cats: 2025 Vet Insights 🐱🌬️

Hello! I’m Dr Duncan Houston BVSc, feline veterinarian and founder of Ask A Vet. In 2025, bronchiectasis—an irreversible dilation and scarring of the bronchi—is increasingly recognized in cats with chronic airway disease. Although rare, its impact on respiratory health and quality of life makes early detection and management vital. This comprehensive guide explores causes, clinical signs, diagnosis, treatment, prognosis, and home-care support via Ask A Vet, Woopf & Purrz. 💙

📌 What Is Bronchiectasis?

Bronchiectasis is a chronic condition marked by permanent dilatation of the bronchi and bronchioles due to destruction of the muscular and elastic components of airway walls :contentReference[oaicite:3]{index=3}. Airway dilation leads to mucus accumulation, bacterial colonization, inflammation, and recurrent infection—a vicious cycle that worsens lung damage :contentReference[oaicite:4]{index=4}.

⚠️ Why It Matters

• Chronic productive cough, tachypnea, exercise intolerance, and intermittent fever are common :contentReference[oaicite:5]{index=5}.
• Hemoptysis (bloody sputum) may occur.
• Bronchiectasis often complicates chronic bronchitis or asthma, and may mimic lung masses on imaging :contentReference[oaicite:6]{index=6}.
• If untreated, progressive lung damage and lowered quality of life result.

👥 Who’s Affected?

• Tends to occur in older cats, especially with chronic respiratory disease or airway infections :contentReference[oaicite:7]{index=7}.
• Cats with primary ciliary dyskinesia, repeated aspiration pneumonia, smoke inhalation, or bronchopulmonary neoplasia are at risk.
• The disease is rare but increasingly reported in cats with feline asthma or chronic bronchitis (~47% incidence in one study) :contentReference[oaicite:8]{index=8}.

🔍 Clinical Signs

• Persistent moist cough productive of mucus or pus.
• Occasional coughing up blood (hemoptysis).
• Exercise intolerance, panting, tachypnea.
• Intermittent fever, lethargy, poor appetite.
• Wheezing or crackles on chest auscultation.

🔬 Diagnostic Approach

1. History & Physical: Chronic cough, prior airway disease, environmental exposures.
2. Thoracic Radiographs: Irregular bronchial patterns, “tram lines,” bronchial wall thickening. May show nodular or mass-like changes :contentReference[oaicite:9]{index=9}.
3. CT Scan: Gold standard for diagnosing and classifying bronchiectasis—cylindrical, varicose, or cystic. Identifies dilated, mucus-filled airways and broncholiths :contentReference[oaicite:10]{index=10}.
4. Bronchoscopy/BAL: Visualize airway damage, obtain samples for cytology and culture.
5. Additional Tests: CBC/chem for infection; airway clearance assessments; possible bronchodilator responsiveness.

🛠️ Treatment Approaches

A. Control Underlying Inflammation

• Anti-inflammatories: inhaled or systemic corticosteroids to reduce bronchial inflammation and secretion :contentReference[oaicite:11]{index=11}.
• Bronchodilators: inhaled albuterol for secondary airway constriction.

B. Manage Infection & Secretion

• Culture-guided antibiotics to treat secondary bacterial infections.
• Inhaled or systemic macrolide antibiotics for anti-inflammatory effects and mucus control :contentReference[oaicite:12]{index=12}.
• Nebulization and coupage (chest percussion) to loosen secretions :contentReference[oaicite:13]{index=13}.
• Hydration support and mucolytic agents may be used.

C. Physiotherapy

• Chest physiotherapy and nebulization: essential to maintain airway clearance and reduce mucus accumulation :contentReference[oaicite:14]{index=14}.
• Consider referral to a physiotherapist skilled in feline respiratory care.

D. Surgical Intervention

• Localized lung lobe resection can be curative if bronchiectasis is confined to a segment and medical control fails :contentReference[oaicite:15]{index=15}.
• Surgery carries risks and should be reserved for severe unilateral disease.

🌱 Prognosis & Monitoring

• Progression is slow with appropriate management; early intervention improves outcomes.
• Regular checks every 3–6 months: clinical exam, imaging, and airway sampling.
• Monitor for exacerbations and adjust antibiotics and physiotherapy accordingly.
• Prognosis depends on cause, extent, comorbidities, and owner compliance.

🏠 Role of Telehealth & Home‑Care Tools

• Ask A Vet: Guides coupage technique, adjusting meds, recognizing flare-ups, and when to escalate treatment.
• Woopf: Delivers nebulizer kits, antibiotics, bronchodilators, and chest physiotherapy aids.
• Purrz: Monitors respiratory rate, coughing frequency, activity level, and alerts to deterioration trends.

🛡️ Prevention & Environmental Measures

• Control feline asthma or bronchitis early to reduce long-term airway damage.
• Avoid smoke, dust, strong odors, and indoor pollutants.
• Ensure proper vaccination and prompt treatment of respiratory infections.
• Maintain good indoor air quality and humidity.

🔬 2025 Innovations & Future Directions

• Point-of-care CT for early detection in high-risk felines.
• Targeted immunomodulatory therapies: macrolide-based mucus reduction, biologics.
• Wearable respiratory monitors via Purrz for early detection of flares.
• Stem-cell therapies aiming to repair airway wall damage currently under research.

✅ Vet‑Approved Care Roadmap

1. Recognize chronic productive cough or respiratory distress—seek veterinary evaluation.
2. Obtain imaging (radiographs, CT) and airway sampling to confirm diagnosis.
3. Start anti-inflammatories, bronchodilators, and culture-based antibiotics.
4. Teach owner coupage and initiate physiotherapy at home.
5. Consider surgery if disease localized and fails medical treatment.
6. Schedule regular monitoring visits and update treatment as needed.
7. Use Ask A Vet, Woopf & Purrz for home monitoring, medication delivery, and flare‑up guidance.
8. Ensure environmental optimization and preventive care to reduce recurrence.
