Cats get eye boogers, also called ocular discharge, for several reasons including normal tear accumulation, infections, allergies, irritants, or anatomical issues. Common causes are conjunctivitis (inflammation of the eye lining), upper respiratory infections, allergies to environmental factors like dust or pollen, blocked tear ducts, and foreign bodies irritating the eye. The discharge helps flush out debris but if excessive, colored, or accompanied by redness or squinting, it could indicate an underlying health issue needing veterinary attention.
Common Causes of Cat Eye Boogers
- Conjunctivitis (Pink Eye): Inflammation causing red, swollen eyes and discharge.
- Allergies: Environmental allergens cause watery eyes and discharge.
- Upper Respiratory Infections: Viral or bacterial infections lead to eye and nasal discharge.
- Blocked Tear Ducts: Prevent normal drainage, causing tears and discharge to accumulate.
- Foreign Bodies: Debris in the eye can trigger irritation and discharge.
Normal vs. Concerning Eye Boogers
- Small amounts of dried crust or clear discharge are normal, especially upon waking.
- Thick, yellow, green, or foul-smelling discharge, or symptoms like redness, swelling, and squinting, indicate an infection or other eye problem requiring veterinary care.
Why Eye Boogers Form
Tears contain water, oils, mucus, and antibodies that keep the eye lubricated, flush out irritants, and fight infection. During sleep or irritation, these tears dry out and accumulate as eye boogers. Certain cat breeds with flat faces may be more prone to excessive tearing due to facial structure. In summary, occasional eye boogers are normal but persistent or abnormal discharge should be evaluated by a vet.
