Conjunctivitis, or pink eye, shows up pretty often in cats.
It brings redness, swelling, and discharge around their eyes, which is uncomfortable for the cat and stressful for owners.
Feline conjunctivitis can start from infections, allergies, or things that irritate the eye.
Spotting the signs early really helps with treatment.
You might see your cat rubbing its eyes or blinking a lot.
Sometimes their eyes look watery or get crusty.
Upper respiratory infections can also play a part, so it’s not always just an eye thing.
Figuring out what’s causing conjunctivitis and knowing what to look for really matters if you want your cat to stay healthy.
This article breaks down what feline conjunctivitis is, what causes it, the symptoms, and how you can treat it.
That way, you’ll know what to do if your cat starts showing signs of pink eye.
Causes and Symptoms of Conjunctivitis in Cats
Conjunctivitis in cats happens when the tissues around the eye get inflamed or infected.
Infections, allergies, or other eye problems can cause it.
You’ll see redness, discharge, and maybe squinting.
Knowing what to watch for means you can get your cat help sooner.
Common Causes in Felines
Infections cause most cases of feline conjunctivitis.
Viruses like feline herpes virus often trigger eye inflammation and discharge.
Bacterial infections such as chlamydophila and mycoplasma can also cause problems, especially in homes with multiple cats.
Allergies can set off conjunctivitis too.
Dust, pollen, or even certain cat litters may irritate the eyes, leading to redness or itching.
Respiratory infections often show up with conjunctivitis, since they affect tissues near the eyes.
Other conditions like blepharitis (eyelid inflammation), entropion (when the eyelid rolls inward), or dry eye can make conjunctivitis worse.
An injury or something stuck in the eye might also start the problem.
Recognizing the Symptoms
Cats with conjunctivitis usually have red, swollen eyes.
Their eyes might water or produce thick discharge.
You could see your cat squinting or keeping its eyes half-closed because it hurts.
The discharge can look clear, yellow, or green.
Some cats rub their eyes a lot or act sensitive to light.
Eyelids might look puffy or get crusted, especially after sleeping.
A pink eye appearance shows up when the conjunctiva gets inflamed.
If these symptoms stick around for more than a week or get worse, you should check for underlying causes like infection or allergies.
Catching it early can help avoid lasting damage.
Complications and Related Eye Conditions
If you don’t treat conjunctivitis, it can turn into bigger eye problems.
Ongoing inflammation sometimes leads to scarring or ulcers, which can hurt and even affect vision.
Sometimes people mistake conditions like glaucoma (high eye pressure) or cataracts for conjunctivitis, but they need different care.
Dry eye can also show up, making the irritation worse because of poor tear production.
Issues like blepharitis and entropion can cause conjunctivitis to keep coming back since they mess with how the eyelids work.
Urinary tract infections (UTIs) don’t cause conjunctivitis directly, but if your cat’s health is already down, infections are more likely.
Keeping an eye on these symptoms helps stop long-term damage.
If you want to know more about related infections, you can check out clinical studies on detecting bacteria in cats with conjunctivitis.
Diagnosis and Treatment Options
A vet checks for conjunctivitis by looking carefully at your cat’s eyes and ruling out other problems.
Treatment can involve medications or some home care, depending on what’s causing the issue.
Keeping your cat’s eyes clean and watching for signs of infection can help prevent future flare-ups.
Veterinary Diagnosis
Your vet starts with a good eye examination to look for redness, swelling, discharge, or ulcers.
Sometimes they’ll take a small swab or biopsy to find out if bacteria, viruses, or fungi are involved, especially if the conjunctivitis keeps coming back or doesn’t get better.
The vet checks if the eye itself is the main problem or if another disease, like an upper respiratory infection, is causing it.
Diagnostic tests help tell eye infections apart from allergies or irritants.
Medical and Home Treatments
If bacteria are the problem, your vet will probably prescribe antibiotic ointment or drops.
For viral infections like feline herpesvirus, antivirals and supportive care usually help.
You can clean your cat’s eyes gently with warm water or saline to ease discomfort.
Some people try diluted organic apple cider vinegar (ACV) at home, but this should only be done with a vet’s okay.
Using the wrong home remedies can make things worse.
Advanced Care and Prevention
If the conjunctivitis is really bad or tied to other eye problems like cataracts or deep infections, your cat might need advanced care.
That could mean specialized treatments or even surgery, but always under a vet’s supervision.
Prevention mostly comes down to regular checkups, gentle cleaning around the eyes, and keeping an eye out for redness or discharge.
Good animal eye care lowers the chance of repeated infections.
