When does a cat's eyes run? - in detail
A cat's eyes may produce discharge or "run" due to various reasons, often related to health or environmental factors. One common cause is conjunctivitis, an inflammation of the conjunctiva, which can result from bacterial, viral, or fungal infections, allergies, or irritants like dust or smoke. Upper respiratory infections, such as feline herpesvirus or calicivirus, can also lead to watery or mucus-like discharge from the eyes. Allergies to pollen, mold, or certain foods may trigger excessive tearing as the body attempts to flush out allergens. Blocked tear ducts, often caused by congenital issues or inflammation, can prevent tears from draining properly, leading to overflow. Foreign objects, such as dirt or small debris, can irritate the eye and cause tearing as a protective response. Additionally, structural abnormalities, like entropion (inward rolling of the eyelid), can cause the eyelashes to rub against the eye, leading to irritation and discharge. Environmental factors, such as dry air or exposure to strong winds, can also dry out the eyes, prompting the production of excess tears. In some cases, underlying systemic conditions, such as feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV), may contribute to eye issues. Regular monitoring of a cat's eye health is essential, as persistent or severe discharge, redness, squinting, or behavioral changes may indicate a more serious problem requiring veterinary attention. Proper hygiene, such as gently cleaning the eyes with a damp cloth, can help manage mild cases, but professional diagnosis and treatment are crucial for addressing underlying causes.
