why is my cat sneezing so much

Cats sneeze much like humans do, usually due to irritation or inflammation in their nasal passages, which triggers a reflex to clear the irritant. Common causes of frequent sneezing in cats include viral upper respiratory infections such as feline herpesvirus and calicivirus, secondary bacterial infections, and fungal infections. Other possible causes are foreign bodies stuck in the nose (like plant material), dental disease affecting the nasal area, allergies or irritants like dust and smoke, nasal polyps, and even tumors or cancer. Sneezing may also be accompanied by other symptoms like nasal discharge (which can be clear, yellow, green, or bloody), eye irritation, reduced appetite, or lethargy. If the sneezing is occasional and your cat appears healthy otherwise, it may be a mild irritation or simple viral infection that could resolve on its own. However, if the sneezing is persistent, very frequent, or accompanied by other concerning symptoms such as thick nasal discharge, bad breath, loss of appetite, or lethargy, it is best to consult a veterinarian for diagnosis and appropriate treatment. Treatment may involve antiviral or antibiotic medications, removal of foreign objects, dental care, or management of allergies or other underlying conditions.
