A cloudy eye in a cat needs attention
A cloudy eye can reflect corneal injury, inflammation, pressure change, lens disease or other conditions that cannot be distinguished safely at home. New cloudiness—especially with squinting, redness, enlargement or vision change—needs prompt veterinary examination.

A cloudy eye in a cat needs attention — the quick answer
✓ Prevent rubbing, avoid human eye drops and arrange a same-day assessment.
✓ Sudden cloudiness with pain, enlargement, trauma or vision loss is an emergency.
✓ This information supports observation and does not replace veterinary diagnosis.
Identify whether cloudiness is on the surface, inside the eye or over the pupil and note pain or discharge. This guide explains what to record, what not to do and when veterinary care becomes urgent.
Describe the cloudiness without touching the eye
Note whether one eye or both are affected and whether the haze seems on the clear surface, behind the pupil or throughout the eye. Record colour, onset, discharge, redness, pupil size and any recent scratch, fight or collision. Use photographs in ordinary light without flash; never press the eyelid or eye to test pain or firmness, and do not force the eye open.
Assume squinting means discomfort
Squinting, keeping the eye closed, rubbing, avoiding light, tearing and a raised third eyelid commonly signal pain. Cats may otherwise eat and behave almost normally. A corneal ulcer can cause clouding and discharge, while inflammation or glaucoma may also alter clarity. Outward appearance cannot identify which treatment is safe, so do not wait for appetite to change.
Use no unprescribed eye drops
Do not apply human redness relievers, contact-lens solution, ointment, leftover antibiotic or steroid drops. Steroids can worsen corneal ulcers and delay healing. Do not remove a stuck object or rinse a penetrating injury. After a known chemical splash, call immediately for exact flushing and transport instructions and keep the product label. Home treatment can cost valuable time.
Arrange prompt eye testing
Keep the cat indoors away from rough play and ask whether a protective collar is needed. Veterinary assessment may include fluorescein dye for corneal damage, measurement of eye pressure, pupil responses and examination of the cornea, anterior chamber, lens and retina. These tests separate conditions that look alike but require opposite treatment. New cloudiness should not be monitored for several days without triage.
Recognise a same-day or emergency eye problem
Cloudiness with squinting, redness, discharge, trauma, unequal pupils, visible blood, enlargement or apparent vision loss needs same-day urgent care. Sudden blindness, a protruding or severely injured eye, major head trauma, collapse or neurologic signs is an emergency. Early treatment may protect comfort and vision, so call before waiting for the eye to clear and transport without pressure around the head.

A broken cat tooth may expose sensitive tissue or hide damage below the gumline even when the cat still eats. Prevent hard chewing, do not test or file the tooth and arrange a veterinary dental assessment; facial trauma, jaw misalignment or heavy bleeding is urgent.
