Causes and Triggers

Common Triggers

Environmental Allergens & Irritants:

• Indoor Allergens: Dust, dust mites, mold spores.
• Airborne Irritants: Cigarette smoke, fireplace smoke, perfumes, air fresheners, aerosol sprays, and essential oils.
• Household Products: Scented cleaning products and dusty cat litter.
• Other Factors: Pollen (seasonal), cold air, and significant stress.

Risk Factors

• Age: Most commonly diagnosed in cats aged 2-8 years.
• Breed Predisposition: Siamese and other Oriental breeds are at higher risk.
• Lifestyle: Indoor cats may have higher exposure to concentrated indoor allergens.
• Health Status: Obesity can exacerbate breathing difficulties.
• Gender: Females may be slightly more frequently affected.

Recognizing the Symptoms

Early Warning Signs

Respiratory Symptoms:

• Coughing: A dry, hacking, or gagging cough, often mistaken for a hairball.
• Wheezing: A high-pitched whistling sound during breathing.
• Increased Respiratory Rate: Breathing faster than normal while at rest.
• Labored Breathing: Visible effort using abdominal muscles.
• Posture: Crouching low to the ground with neck extended forward.

Behavioral Changes:

• Lethargy and reduced activity levels.
• Decreased appetite.
• Hiding or seeking isolation.
• Restlessness or inability to get comfortable.

Asthma Cough vs. Hairball

Emergency Symptoms: Seek Immediate Vet Care

These signs indicate a life-threatening asthma attack:

• Cyanosis: Blue or purple tinge to gums or tongue.
• Open-Mouth Breathing: Especially if accompanied by distress.
• Severe Lethargy or Collapse.
• Extreme Difficulty Breathing: Using abdominal muscles heavily, elbows held out from body.

Diagnosis

Veterinary Examination

Your vet will perform a thorough physical exam, assessing respiratory rate/effort, listening for wheezing or crackles in the lungs, checking gum color, and evaluating overall condition.

Diagnostic Tests

Baseline Testing:

Advanced Testing (if needed):

• Bronchoscopy: Direct visualization of the airways.
• Bronchoalveolar Lavage (BAL): Collects fluid/cells from lungs for analysis.
• CT Scan: Provides detailed 3D imaging of the chest.
• Allergy Testing: To identify specific environmental triggers.

Differential Diagnosis

Conditions with similar symptoms must be ruled out:

• Heart disease or heartworm
• Pneumonia
• Lung parasites
• Pleural effusion (fluid around lungs)
• Cancer or foreign body inhalation

Treatment Options

Emergency Treatment for Acute Attacks

• Oxygen Therapy to stabilize breathing.
• Injectable Bronchodilators (e.g., terbutaline) to open airways quickly.
• Injectable Corticosteroids (e.g., dexamethasone) to reduce inflammation.
• Hospitalization for monitoring and supportive care in severe cases.

Long-Term Management Medications

1. Corticosteroids (Reduce Inflammation):

2. Bronchodilators (Open Airways):

Inhaler Therapy with the Aerokat Chamber

Benefits:

• Delivers medication directly to the lungs.
• Minimizes systemic side effects compared to oral steroids.
• Highly effective with proper training.

How to Use:

1. Place the mask gently over the cat's nose and mouth.
2. Actuate the inhaler once.
3. Hold the chamber in place for 7-10 breaths.
4. Reward your cat immediately to create a positive association.

Treatment Protocols by Severity

• Mild Asthma: Environmental management + bronchodilator as needed.
• Moderate Asthma: Daily inhaled corticosteroid + environmental control + rescue inhaler.
• Severe Asthma: May start with oral steroids, then transition to inhaled steroids + chronic bronchodilator therapy. An emergency plan is essential.

Initial Diagnostic Costs

Ongoing & Annual Costs

Monthly Medication (Approximate):

• Inhaled Corticosteroid (Flovent/Flixotide): $45 - $90
• Inhaled Rescue Bronchodilator (Albuterol): $30 - $60
• Aerokat Chamber: $65 - $85 (one-time purchase)

Annual Estimated Costs (Medications + Monitoring):

• Medications: $600 - $1,500
• Follow-up Exams & X-rays: $300 - $700
• Total Annual Management: $900 - $2,200

Emergency Care Costs

A severe asthma attack requiring hospitalization can cost $1,500 to $4,000+, depending on severity and duration of care.

Environmental Management: Your First Line of Defense

Reducing Triggers at Home

1. Improve Air Quality:

   • Use HEPA air purifiers in main living areas and bedrooms.
   • Absolutely no indoor smoking of any kind.
   • Avoid candles, incense, plug-in air fresheners, and strong perfumes.

2. Dust & Allergen Control:

   • Vacuum frequently with a HEPA-filter vacuum.
   • Wash cat bedding and soft furnishings weekly in hot water.
   • Use a damp cloth for dusting to avoid stirring particles into the air.

3. Litter Box Strategy:

   • Switch to a low-dust, unscented litter. Formulas like silica gel or certain recycled papers are excellent.
   • Consider Dr. Elsey's Respiratory Relief litter, designed for sensitive cats.
   • Place the litter box in a well-ventilated but low-traffic area.

4. Household Products:

   • Choose fragrance-free, hypoallergenic cleaning products.
   • Avoid aerosol sprays; use pump or roll-on alternatives.

Seasonal Considerations

• Spring/Summer: Keep windows closed on high-pollen days; use air conditioning.
• Fall/Winter: Dry air from heating can irritate airways; consider a humidifier. Protect your cat from breathing very cold air directly.

Monitoring Your Cat at Home

Tracking Respiratory Rate

• Normal Resting Rate: 20-30 breaths per minute.
• Cause for Concern: A consistent resting rate above 40 breaths/minute.
• How to Count: Watch the chest rise/fall for 15 seconds, multiply by 4. Do this when your cat is asleep or calmly resting.

Maintain an Asthma Diary

Log daily:

• Number and severity of coughing episodes.
• Resting respiratory rate.
• Activity level and appetite.
• Medication given and any potential triggers noticed (e.g., cleaning day, new product).

When to Contact Your Veterinarian

• Schedule a Visit: For increased cough frequency, subtle changes in breathing, or decreased activity.
• Go to Emergency Vet Immediately: For any signs of respiratory distress, open-mouth breathing, blue gums, or collapse.

Prognosis and Quality of Life

With consistent, proper management, the prognosis for asthmatic cats is very good. Most achieve:

• An excellent quality of life and normal lifespan.
• Significant reduction or elimination of acute attacks.
• The ability to live active, happy lives.

Key Factors for Success:

1. Owner commitment to medication and environmental changes.
2. Regular veterinary check-ups.
3. Early intervention during flare-ups.

Living with an Asthmatic Cat: Daily Tips

• Medication Routine: Administer medications at the same time each day. Use treats and praise to create a positive experience, especially with the inhaler.
• Stress Reduction: Maintain a predictable routine. Use synthetic pheromone diffusers (like Feliway). Provide safe, quiet hiding spots.
• Emergency Preparedness:
  • Keep your rescue inhaler (albuterol) easily accessible and know how to use it.
  • Have your vet's emergency number and the address of the nearest 24-hour animal hospital saved.
  • Keep a copy of your cat's medical records and current medication list.

Myths and Facts

Conclusion

Feline asthma is a serious but highly manageable condition. The cornerstone of success is a partnership between you and your veterinarian, combining appropriate medication with diligent environmental control. By recognizing the signs early, committing to treatment, and creating a low-irritant home, you can help your asthmatic cat breathe easier for years to come.
