Inflammation of the third eyelid in a cat: causes and treatment
The third eyelid in a cat is not just an aesthetic problem. This can be a serious pathology leading to various diseases, as well as a decrease in vision in an animal.
The fold of the conjunctiva, called the third eyelid, is located in the corner of the eye and consists of a thin mucous membrane – the nictitating membrane. In a normal state, the nictitating membrane lines the inside of the eyelid, and also envelops the eyeball. It moisturizes the cornea and cleanses the eyes of dust and specks.
