Scratches, splashes, thorns and knocks: the calm playbook for a frightening five minutes.

Feline eye injuries arrive in four broad shapes: scratches from play, prey or brambles; foreign bodies, the grass seed or grit lodged under a lid; chemical splashes from cleaning products and garden treatments; and blunt knocks from falls, doors and collisions. Each has its own first response, which is why the first job is a careful look rather than a reflex.
The look is observation only: a good light, no touching, noting whether the eye is open or clamped, whether anything is visibly stuck, whether the surface looks scratched or cloudy, and whether the pupil matches its partner. Thirty seconds of information changes everything that follows.
The injured eye playbook is defined by its prohibitions: never attempt to remove anything embedded in or stuck to the eye itself, because withdrawal can turn a puncture into a rupture, and that extraction belongs to a vet with sedation available; never apply human eye drops, ointments or leftover pet medications; never force a clamped eye open to inspect it.
And do not delay for observation’s sake: unlike a limp or a tummy upset, an eye injury has no safe watch and wait tier. The only injuries that get home treatment first are chemical splashes, and only because their first aid genuinely cannot wait for the car.
A chemical splash, cleaning spray, disinfectant, garden product, is the single eye emergency where home action precedes the journey: flush the eye immediately and generously with lukewarm water or saline, poured steadily from a jug or run gently from a slow tap, for a full ten to fifteen minutes, holding the lids open as best two people and a towel wrap allow.
It feels endless and it is the treatment: dilution now determines damage later. Bring the product container or a photo of its label to the vet, because the ingredients dictate what happens next, and ring the practice during or immediately after the flush so they are ready for you.
For scratches, embedded objects and blunt trauma, the winning response is masterly inactivity performed quickly: the cat lifted calmly into the carrier, a towel over most of it to dim the frightening world, no food or drink in case sedation is needed, and the drive made with the practice already rung so the eye is triaged on arrival, not from the waiting room queue.
If the cat is pawing frantically at the eye and you have a soft protective collar from a previous adventure, fitting it prevents self inflicted upgrades en route. What the injured eye needs from its human is transport and restraint, in both senses.
The clinical sequence is reassuringly methodical: pain relief and, where needed, sedation first, because no eye can be examined at war; then the fluorescein dye to map surface damage, a proper look under and behind the lids for stowaways, and pressure or imaging checks when blunt trauma raises deeper questions.
Treatment follows the finding: foreign bodies lifted under sedation, scratches managed on the ulcer protocol our corneal ulcer guide describes, chemical burns treated by severity, and the rare severe traumas referred to ophthalmology. The overwhelming majority of promptly presented eye injuries heal completely; the eyes that lose that bet nearly always lost time first.
Home care afterwards is simple and strict: drops given at the prescribed frequency to the finished course, the collar worn every unsupervised minute however operatic the protest, rechecks kept because eyes are re dyed to prove healing rather than assumed healed, and any backslide, renewed squinting, discharge, cloudiness, reported the day it appears.
Healing eyes ask roughly a fortnight of nuisance in exchange for a lifetime of function, and the collar is the whole difference in many cases. Hold the line; the eye is worth it.
Most household eye injuries happen in two seconds of overexcited wrestling, so the post squabble ritual is worth installing: when a play fight has run hot, glance both combatants over once the dust settles, eyes especially, looking for the new squint, the watering eye, the reluctance to face the light.
Check the apparent winner as carefully as the loser, because claws do not respect narrative. Most checks find nothing and cost ten seconds; the one that finds a squint has just bought that eye its same day appointment at the earliest possible moment.
Summer and the catio bring the foreign body season of grass seeds, husks and grit: material that lodges under a lid and announces itself as a suddenly, violently irritated eye, often one sided, with frantic pawing and a refusal to open. Grass awns are barbed and migrate; they do not wash out on their own goodwill.
Do not go hunting under lids at home: the removal needs anaesthetic drops, good light and instruments. Your jobs are the collar, the carrier and the call, plus a mention of where the cat had been, because gardens and hay change what the vet expects to find.
Once an injured eye is treated, the week that follows has a shape: comfort improving day on day, the eye opening progressively, discharge drying up, and the recheck confirming with dye what appearance suggests. Your job is drops on schedule, the collar enforced, and a daily thirty second comparison of the two eyes in good light.
Off script means back in: pain returning after improvement, discharge turning thick or coloured, new cloudiness, or an eye that plateaus rather than progresses. Healing that stalls has a reason, and the recheck exists to find it early.
Eye injury prevention is unglamorous housekeeping: claws trimmed on schedule so play swipes stay blunt, rough games channelled onto wand toys rather than hands and faces, garden chemicals and sprays stored and used away from animals, and doors closed with a glance for the cat who escorts everyone everywhere.
Add the catio walkover in seed season, clearing long seeding grasses at face height, and the odds fall further. None of it eliminates the two second accident, which is why the squabble ritual and the same day rule remain the real safety net.
Eye injuries are the library’s purest emergency: any squinting, bleeding, cloudiness or visible wound after a knock or scratch means the vet today, and a protruding or displaced eye means now. Chemicals are the one exception where home action comes first: flush with copious lukewarm water, then travel. Everything else is a collar, a carrier and a phone call.
Regularly: play scratches from housemates lead the list, followed by household chemical splashes, door edges and DIY dust. Indoor living removes the road, not the physics.
No: corneal scratches hurt in waves and complications build over days, and only the dye test shows the damage. Fine looking after a known scratch still means today’s appointment.
That is a now emergency: keep the eye moist with saline soaked gauze if instantly available, prevent all contact, and travel immediately while someone phones ahead. Minutes genuinely matter.
No home bandaging: pressure on an injured eye can do real harm. The collar and a towel wrap are the protection; covering is the clinic’s decision with the injury visualised.
Healthy play is good for both; the management is claws trimmed, sessions redirected onto toys when they run hot, and the ten second eye check afterwards. You are not banning the game, just blunting it.
