Cat Asthma Symptoms, Diagnosis, and Treatment: A Comprehensive Guide to Understanding and Managing Feline Asthma
Cat asthma, also known as feline allergic airway disease, is one of the most common respiratory diseases in cats. It is a chronic inflammatory disease that affects the cat's airways, causing difficulty breathing, coughing, and other respiratory symptoms. This article will delve into the symptoms, diagnosis, and treatment options for cat asthma, helping you better understand this condition and provide effective treatment for your feline companion.
Understanding the Feline Respiratory System
The feline respiratory system is primarily responsible for providing oxygen to the body and expelling carbon dioxide. With each breath, air travels through the nose, trachea, and ultimately reaches the lungs. In the lungs, blood exchanges oxygen and carbon dioxide, after which carbon dioxide is expelled through the same path, and oxygen is transported by blood to every cell in the body. This process is similar to the human respiratory process.
A healthy cat's respiratory rate generally ranges from 30-40 breaths per minute. When a cat's breathing rate exceeds this range, or when there are noticeable symptoms of difficulty breathing, such as open-mouth breathing or noticeable shortness of breath, there may be a respiratory problem. Additionally, cats typically don't cough, so if you notice frequent coughing in your cat, it could also indicate a respiratory illness.
Overview of Cat Asthma
Cat asthma, similar to human asthma, is one of the most common respiratory diseases and is an allergic reaction to environmental allergens. This disease can cause cats to wheeze, have difficulty breathing, and cough. Due to inflammation in the airways, the cat's trachea can swell, leading to increased secretions. Excessive secretions can cause mucus plugs to form, which can block the trachea.
When a cat is exposed to an environment containing allergens, it will inhale the allergens into the airways, causing the smooth muscles of the trachea to contract suddenly and become inflamed. If the symptoms persist and treatment is delayed, the condition can worsen, potentially leading to irreversible airway obstruction, preventing the cat from exhaling, causing expiratory dyspnea. Ultimately, it can develop into emphysema and bronchiectasis.
Compared to humans and dogs, cats have a significantly higher number of eosinophils in their airways, which is one reason why cats are more prone to asthma. Allergic airway reactions are typically caused by airway mucosal lesions and allergic reactions. Common allergens include grass pollen, cigarette smoke, aerosols (hair, dander, fleas), unclean litter boxes, polluted air, air fresheners and deodorizers, incense, and cold outdoor air. Asthma can occur in cats of any age, but it is most common in cats between 2 and 8 years old.
Symptoms of Cat Asthma
Coughing: Coughing is the most common symptom of cat asthma in 80% of cases.
Sneezing:
Wheezing:
Cat assumes a hunched posture with the neck extended forward:
Severe cases may experience difficulty breathing:
Diagnosing Cat Asthma
Radiographic examination: Chest X-rays can reveal a ground-glass appearance in the lungs with thickening of the airway walls.
Cytological examination: Bronchoalveolar lavage fluid may reveal a high number of eosinophils (approximately 20% of asthmatic cats have increased eosinophils in peripheral blood). Bacterial culture and antibiotic sensitivity testing of the lavage fluid can determine if there is an infection.
Heartworm test: For cats with coughing symptoms, it is advisable to perform a heartworm test to rule out the possibility of heartworm infection.
Treating Cat Asthma
Oxygen therapy: Providing oxygen to cats with difficulty breathing can alleviate respiratory symptoms.
Corticosteroids and bronchodilators: Used to reduce inflammation, relieve symptoms, and prevent respiratory distress. These medications may need to be administered long-term.
Antibiotics: If a lung infection develops, antibiotics are necessary.
Inhaled medications: Inhaled corticosteroids can be administered using a metered-dose inhaler, spacer, and mask, serving as an alternative to oral corticosteroids. Long-term use of inhaled corticosteroids does not cause side effects associated with corticosteroids.
Treatment for asthmatic cats requires adjustments to medication dosage and frequency based on the veterinarian's assessment to achieve optimal treatment outcomes.
Preventing Cat Asthma
Keep your cat's living environment clean: Regularly clean your cat's living space to remove allergens such as dust, hair, and dander.
Use safe cleaning products: Avoid using cleaning products with irritating ingredients, such as air fresheners and deodorizers.
Prevent your cat from exposure to allergens: Minimize your cat's exposure to allergens like pollen and cigarette smoke.
Schedule regular checkups for your cat: Regular veterinary checkups can help detect and treat asthma early.
Conclusion
Cat asthma is a common respiratory illness that requires timely diagnosis and treatment. Maintaining a clean living environment for your cat, reducing exposure to allergens, and scheduling regular checkups can effectively prevent cat asthma. If your cat exhibits symptoms such as difficulty breathing or coughing, it is important to take them to the veterinarian immediately.
