Upper respiratory infections (URIs) in cats are common and typically involve viral or bacterial pathogens affecting the nose, throat, and sinuses. Symptoms include sneezing, nasal discharge, coughing, and watery eyes. URIs are often spread through close contact with infected cats and can be exacerbated by stress or underlying health issues. While many cases resolve with supportive care, such as keeping the cat hydrated and comfortable, severe or persistent infections may require veterinary intervention to prevent complications and ensure recovery.
