Cat with yellowish-green discharge from one eye

Usually, when a cat has yellowish-green discharge from one eye, it indicates inflammation of that eye. This can be due to various reasons such as conjunctivitis, keratitis, third eyelid hyperplasia, scleritis, or nasolacrimal duct obstruction. This condition is likely caused by injuries to the eye during play or jumping, bacterial infections, scratching of the eye, exposure to cold air, temperature drops, or upper respiratory infections.

How to judge if cat's eye discharge is healthy

Cat eye discharge can be caused by various factors, and the color of the discharge can be divided into several types:

White or translucent discharge: Normal
Black discharge: Usually dried out
Yellow discharge: Inflammation due to heat
Green discharge: Inflammation, such as conjunctivitis and keratitis
Red discharge: Trauma
Pus-like discharge: Cat cold or feline upper respiratory tract infection

Causes of cat eye inflammation

Dietary reasons: Cat food that is too hot and spicy can cause the cat to become overheated and develop inflammation symptoms.
Physical stimulation: Dust infection, foreign objects in the eye, scratches, and injuries.
Eye problems: Conjunctivitis, keratitis, and eye infections.
Bacterial infections: Feline upper respiratory tract infections, caused by herpesviruses. Symptoms include coughing, purulent nasal discharge, and sneezing, which are similar to cat colds. Treatment is required promptly at a veterinary hospital, and vaccines should be administered on time.

How to care for and treat

It is not recommended to treat eye infections at home with eye drops or ointments. Human medications should not be used either. It is best to take the cat to a pet hospital for inspection and confirmation, and then use medication accordingly to avoid eye damage. Regular home care should include preparing an Elizabethan collar, several cotton swabs, physiological saline, and gentamicin ointment. Cleaning the cat's eyes regularly can maintain good health.
