If a cat scratched your eye, rinse it immediately with clean water or saline solution and get to a doctor the same day. Cat claws carry bacteria that can infect a corneal scratch quickly, so even a minor-feeling injury needs professional evaluation. Most superficial scratches heal within 24 to 48 hours with proper treatment, but delays raise the risk of infection and scarring.
Flush Your Eye Right Away
Your first step is rinsing. Use clean water or saline solution, holding a small clean cup with its rim resting against the bone at the base of your eye socket. Let the liquid flow across the eye to wash out any debris. If you’re near a workplace eye-rinse station, use it.
After rinsing, blink several times. You can also gently pull your upper eyelid over your lower eyelid, which triggers tearing and may help flush out tiny particles. That’s where the self-care ends. There are several things you should not do:
- Don’t rub your eye. This can deepen the scratch or grind debris into the cornea.
- Don’t touch your eye with cotton swabs, tweezers, or anything else.
- Don’t try to remove anything that appears stuck in or on the eye.
- Don’t wear contact lenses until the injury has fully healed and a doctor clears you.
Why Cat Scratches Need a Doctor Visit
A scratch on your skin from a cat is one thing. A scratch on your cornea, the clear front layer of your eye, is more serious for two reasons. First, the cornea is delicate tissue that can scar permanently if a wound gets infected or doesn’t heal properly. Deep abrasions through the center of the cornea can leave a scar that affects vision even after healing. Second, cat claws harbor bacteria that skin wounds can often fight off but the eye cannot.
The bacterium Bartonella henselae, which causes cat scratch disease, lives on the claws of domestic and feral cats, especially kittens. While cat scratch disease most commonly causes swollen lymph nodes, it can rarely infect the eye directly. Beyond that specific bacterium, claws pick up bacteria from litter boxes and soil that can cause a secondary eye infection on top of the physical scratch.
A doctor will typically prescribe antibiotic eye drops or ointment to prevent infection. For most corneal abrasions, a short course of antibiotic ointment for about three days is standard. Deeper or more concerning scratches may call for antibiotic drops used four times daily along with lubricating eye drops to keep the surface moist during healing.
What a Corneal Scratch Feels Like
You’ll likely notice symptoms right away, though some take a few hours to fully develop:
- Sharp pain or a gritty feeling, like something is stuck in your eye
- Watery eyes and excessive tearing
- Redness and swelling around the eye or eyelid
- Blurred vision in the affected eye
- Sensitivity to light, sometimes intense enough that opening your eye in a bright room is uncomfortable
These symptoms overlap with early signs of infection, which is partly why a professional exam matters. You can’t easily tell at home whether the scratch is superficial or deep, or whether bacteria are already taking hold.
Managing Pain While You Heal
Corneal scratches hurt disproportionately to their size because the cornea is packed with nerve endings. Over-the-counter oral pain relievers like ibuprofen or acetaminophen can help, but prescription options work better for many people. A systematic review of pain treatments found strong evidence that prescription anti-inflammatory eye drops significantly reduce pain at 24 and 48 hours and cut the need for oral painkillers by about 53%. Ask your doctor whether these drops make sense for your injury.
Keeping the eye closed or wearing sunglasses can ease light sensitivity. Some people find a dark room helpful for the first day. Artificial tears or lubricating drops (your doctor may prescribe these alongside antibiotic drops) reduce the gritty, dry sensation that makes you want to rub your eye.
How Long Recovery Takes
Most small, uncomplicated corneal abrasions heal completely within 24 to 48 hours. Larger or deeper scratches typically take three to five days. During this time you’ll notice the pain gradually fading and your vision clearing up. If you wear contact lenses, you’ll need to stay out of them until the surface has fully healed and your eye doctor confirms the cornea can tolerate them again.
If your eye isn’t feeling better after 24 hours of following your prescribed treatment, contact your provider. A scratch that doesn’t improve or gets worse may be developing an infection, which needs different or more aggressive treatment to prevent scarring.
Signs You Need Emergency Care
Most cat scratches to the eye are superficial abrasions that heal well with prompt treatment. But certain symptoms signal a more serious injury that warrants an emergency room visit rather than waiting for a regular appointment:
- A visible cut or puncture on the eyeball itself
- Blood visible inside the eye, between the cornea and the iris (the colored part)
- Pupils that are different sizes
- Severe or worsening pain with nausea or headache
- Sudden significant vision changes, such as double vision or a large area of blurriness
These can indicate a deeper laceration, internal bleeding in the eye, or damage to structures behind the cornea. They’re uncommon from a typical cat swipe but possible, especially from a direct claw strike.
Tetanus and Cat Scratches
Cat scratches fall into the “dirty wound” category under CDC guidelines because claws carry saliva and bacteria. If your last tetanus booster was five or more years ago, your doctor may recommend one. If you’ve never completed a full tetanus vaccine series or don’t remember your vaccination history, a booster is more clearly indicated. This is worth mentioning at your appointment, since the focus will naturally be on your eye and it’s easy to overlook.
