Cat symptom guide: Eye injury or sudden squinting — the quick answer
✓ Treat this as urgent
✓ Prevent rubbing and arrange urgent same-day veterinary care; do not use human drops.
✓ Record timing, frequency and related changes
A symptom is information, not a diagnosis. Eye pain, cloudiness, trauma or holding an eye closed can deteriorate quickly. When in doubt, a veterinary professional can triage the situation using your cat's age, history and current signs.
What this sign can look like
Eye pain, cloudiness, trauma or holding an eye closed can deteriorate quickly.
What to do now
Prevent rubbing and arrange urgent same-day veterinary care; do not use human drops.
Useful information for the clinic
Note when it began, frequency, appetite, drinking, litter use, medication and possible exposures. Take a short video only if it is safe and does not delay care.
Protect the eye on the way to care
Keep the cat indoors in a dim, quiet room and prevent rubbing when safely possible. Do not hold the eyelids open, remove an embedded object or apply human drops, leftover antibiotics or skin medication. If a loose irritant is suspected, call the clinic before rinsing because trauma and chemicals require different first aid.
Treat rapid change as urgent
Contact an emergency veterinarian for a protruding eye, visible wound, chemical exposure, marked swelling, blood, severe pain or sudden vision loss. Bring the product label after chemical exposure without delaying departure. A small scratch may look minor but can deepen or become infected, so improvement at home does not replace examination.

A cat that stops eating needs same-day veterinary advice, especially when the change is sudden or accompanied by vomiting, weakness, pain or hiding. Do not wait several days for hunger to win.
