Contact a vet about new or persistent eye discharge, especially when the eye is red, cloudy, swollen, held closed or painful. Eye problems can worsen quickly, so do not try leftover drops or human products.
Observe both eyes and the whole cat
International Cat Care advises watching for discharge, redness, cloudiness and discomfort. Note whether one or both eyes are affected, the colour and amount of discharge, sneezing, appetite and any recent injury.
Prevent rubbing and further injury
Keep the cat indoors in a calm, dimmer room while seeking advice. Do not force the eyelids open or remove an embedded object. If your cat is pawing at the eye, ask the clinic how to prevent self-trauma before travel.
Use only instructed cleaning
A veterinary professional may advise gentle cleaning with a specific solution and method. Avoid tea, salt mixtures made at home, cosmetic wipes and medication prescribed for another animal. Never use steroid eye drops without examination.
Prepare for the appointment
Take a clear photograph if it does not delay care, list medicines and record when the change began. Transport the cat securely. A covered retreat such as the Koda Pod may be comforting at home, but it is not a place to delay assessment.
