Cat eye infection is a common issue that can affect cats of all ages. Recognizing the signs early and providing proper care can help prevent discomfort and more serious health problems. In this article, we’ll explore the causes, symptoms, treatments, and prevention strategies for cat eye infections.
What Is a Cat Eye Infection?
A cat eye infection occurs when harmful microorganisms like bacteria, viruses, or fungi invade the eye, leading to inflammation and discomfort. The most commonly affected area is the conjunctiva—the thin membrane covering the white part of the eye and the inner eyelids. This condition is often referred to as conjunctivitis or “pink eye.”
