What does the term 'conjunctivitis' refer to in cats?

The term 'conjunctivitis' specifically refers to the inflammation of the conjunctiva, which is a thin membrane that lines the inside of the eyelids and covers the white part of the eyeball. In cats, this condition can result from various factors, including infections, allergies, or irritants, leading to symptoms such as redness, discharge, swelling, and discomfort in the affected eye. Understanding this term is important for diagnosing and treating ocular issues in cats, as timely intervention can prevent complications and improve the animal's quality of life. The other options pertain to different bodily systems and conditions that do not relate to the eye, making them inaccurate descriptions of conjunctivitis.
