why is my cat crying tears?

Excessive tearing in cats, medically termed epiphora, is a physical symptom, not an emotional response like human crying. When a cat's eyes water, it signals irritation, injury, or an underlying health condition. Common causes include foreign objects such as dust, hair, or debris irritating the eye surface, or environmental allergies to pollen or household irritants.

Ocular infections are a frequent culprit. These can be bacterial, viral (like feline herpesvirus, which often causes recurrent conjunctivitis), or fungal. Corneal injuries, such as scratches or ulcers, also lead to significant tearing and pain. Additionally, structural issues like blocked tear ducts prevent normal tear drainage, causing overflow. Certain breeds, particularly brachycephalic (flat-faced) cats like Persians, are predisposed to tearing due to their facial anatomy, which can lead to eyelid abnormalities or narrow tear ducts.

If your cat is crying tears, observe for other symptoms like redness, squinting, pawing at the eye, discharge (clear, yellow, or green), or changes in appetite/behavior. Prompt veterinary evaluation is crucial to identify the cause, initiate appropriate treatment, and prevent potential complications, including chronic pain or vision impairment. Never attempt to self-diagnose or treat eye conditions without professional guidance.
