Chronic cough in cats can be caused by a variety of things. Coughing is in fact a reflex action of the body to clear the air passages of any irritant or blockage. A blockage in the airways may be caused by a lot of things including:

• Disorders of the respiratory tract including bacterial, viral or parasitic infections
• Aspiration pneumonia which can occur when a cat swallows food or something else which enters the respiratory tract rather than the digestive tract
• Tumors or abnormal growth on the cat’s throat 
• A foreign body stuck in the cat’s respiratory passages
• Heart disease
• Allergies

Your Katy, TX veterinarian has to conduct a thorough physical exam of your cat as well as your pet’s history. Several tests and procedures may also be performed including a complete blood count (CBC), a biochemistry profile, urinalysis, CT scan, MRI, and X-rays. A tracheoscope, laryngoscope, or bronchoscope may be used to take a closer look at the cat’s upper respiratory tract. To learn more, visit this website Well Pet Center (The Well Pet Center).
