Quick answer: Chronic rhinitis means long-term inflammation of the nasal passages, causing ongoing sneezing, nasal discharge, and congestion. In cats, it often follows damage from feline herpesvirus, leaving the nose prone to recurring bacterial infections. Other causes, such as polyps, dental disease, fungal infections, foreign bodies, and tumors, should be ruled out. It’s usually managed rather than cured.
Signs

- Snoring or noisy breathing
