Causes
Infections (viral, bacterial, fungal), allergies, foreign bodies (grass awns), dental problems that connect with the nose, and tumours in chronic cases.
Diagnosis
Examination plus tests according to the suspected cause: rhinoscopy, X-ray or CT scan, cultures, and biopsy in chronic cases.
Treatment
It depends on the cause: treating the infection, removing the foreign body, managing the allergy. Chronic rhinitis can be difficult to resolve completely.
Prevention
Vaccination (in cats), avoiding irritants, and addressing dental problems promptly.
