Cat eye infections are a common problem for cat owners. These types of infections can occur when the tear ducts become inflamed due to allergic reactions, infection, or injury. If you notice your kitty’s eyes becoming red and swollen with cloudy discharge on either side of the pupil it may be time to visit the vet!.

Cats are often the subject of an infectious bacterial eye infection called FELINE CEPHALITIS. It is commonly seen in cats, but can be deadly to them if not taken care off quickly. When your cat has symptoms like swollen eyelids and discharge coming from one or both eyes, it’s time for a visit to the vet!

Cat eye infections can be caused by a variety of things and the symptoms will vary depending on what is causing it. The most common cause for cat eye infections is an infection from bacteria or fungi.

A multitude of factors may cause cat eye infections, some of which are more dangerous than others. If your cat’s eyes seem to be infected, you should get treatment as soon as possible to prevent more severe health problems. 

What do cat eye infections look like, if you’re wondering? You should be aware that tears, redness, and discharge are common symptoms. Here’s all you need to know about cat eye infections.

Infections in the eyes of cats and other eye problems 

Your cat may have an eye infection if his or her eyes are clouded, red, or swollen. Also, if your cat has a lot of pawing at his or her face and has cat eye discharge, this might be an indication of an eye infection. There are a few different forms of cat eye infections and eye disorders to be aware of. 


Infections of the cat eye may be viral, bacterial, fungal, protozoal, or parasitic. Conjunctivitis, uveitis, and even cataracts may occur as a result of these illnesses. The signs of an upper respiratory infection in cats are frequent.

Eye discharge, weeping, squinting, eye discomfort, redness, ocular cloudiness, and changes in pupil size are all signs to look out for.

Keratitis bacterial or ulcerative

The dome-shaped covering that covers the front of a cat’s eyes is called the cornea. If that surface is damaged, most typically through scratching, feline bacterial keratitis may develop.  


Other than physical force injuries, cats may get ulcers in their eyes. Cats have been known to get burns on their eyes by rubbing their eyes against a rough surface in the past. Chemical burns to the cornea are another prevalent cause of eye burns. This may happen when irritants such as shampoos, chemicals, dust, drywall, or other substances get into the eyes. 

Other issues with the eyes

Cats have distinctive eyes, but they, like people, may suffer from various eye problems. Epiphora, or watery eyes, may be caused by clogged tear ducts. Similarly, keratoconjunctivitis sicca, often known as dry eye, is a persistent absence of tear production that may cause red eyes, irritated corneas, and blindness if left untreated. Allergies, difficulties with the third eyelid, and items being trapped in the eyes may all damage your cat’s vision. 


Cats that have had any form of eye surgery are more likely to get an infection if their eyes are not properly cared for afterward. Bacterial infection or ocular injuries might result from a build-up of discharge or repeated pawing at the inflamed region. 

Bringing your cat to your veterinarian for accurate diagnosis and treatment is the greatest thing you can do for cat eye infection treatment. If you can’t get to the clinic straight away, keep an eye on your cat for additional signs of sickness. Check out this article for signs to check for and what to anticipate when it’s time to take your cat to the veterinarian. 

Keep your cat’s eyes safe. 

There are a few things you can do to maintain your kitty pal’s eyes healthy and bright! Here are six techniques to look after your cat’s eyes. 

  1. Examine your cat’s eyes on a frequent basis. It might be an infection if you observe any lumps, coloring, redness, swelling, cloudiness, excessive tearing, or discharge. Also, notice whether your cat is scratching or rubbing his or her face excessively. Take your cat to the vet if you see this. 
  2. Make an appointment with your veterinarian on a regular basis to prevent significant eye issues. Physical checks and blood tests might help you figure out what kind of treatment your cat need. Eye issues can signal a more serious medical issue. 
  3. Keep an eye on how your cat interacts with the other pets in the house. An injury to the eye caused by another pet is a typical cause of eye disorders. It may be brought on by friendly play or even a brief altercation. However, in any scenario, animal monitoring may help protect your cat’s eyes from being infected. 
  4. If you want to prevent your cat from getting eye issues, keep them indoors. Whether it’s due to stressful experiences, environmental irritants, hazardous chemical interactions, or contact with dangerous microorganisms, the outdoors may easily cause injury to your cat’s eyes. 
  5. Trim your cat’s nails on a regular basis to help prevent your cat from scratching his or her own eyes or the eyes of other pets in the home. This is significant because it prevents germs from forming in a rip in the skin, which may irritate the eye.
  6. Finally, to minimize bacterial overgrowth, keep your cat’s litter box, bedding, and other often used locations clean. All-natural substances are used in the Litter-Robot cleaning spray and wipes, which are meant to remove organic debris, stains, and odor. Your pet will be safe using bio-enzymatic technology in conjunction with plan-based cleansers. Plus, their litter box and area will be cleaner than ever! 

What is a cat stye, exactly?

A stye, also known as a hordeolum, is a red, painful lump that appears around the edge or on the inner portion of the eyelid. It resembles a boil or a pimple, and it may be pus-filled.

Styes are caused by an acute infection of the eyelid’s oil glands, and they appear after the glands have gotten blocked. As a consequence, the eye may become inflamed and itching. Swelling, pain while blinking, light sensitivity, and watering of the eye are some of the other symptoms. 

What are the symptoms of a cat stye?

Examine your cat’s eyelid if you find it is bloated, discharges pus, or causes your cat to scratch his or her eyes. If you have a stye, you’ll notice a little lump on the outer or inner portion of your eyelid that appears like a pimple or boil. 

What causes a stye in a cat?

Styes may develop in cats for a variety of reasons, including heat, allergic responses, and even diabetes. Let’s look at some of the several ways your cat might obtain a stye.

Moisture and heat

Heat and moisture in the air may create a breeding habitat for fungus, which can infect your cat with fungal illnesses. If fungi are prevalent in the environment, they may enter your cat’s system via a cut in their skin, resulting in the formation of a stye. 

Fungi may be found in soil, dung, and the environment in general. Simply stroking your cat’s face if there is a breach in their skin near or around the eyelid might transfer germs into the eye, resulting in a stye. 

Reactions due to allergies

Pollen, dust, smoking, shampoo, fleas, pesticides, and other parasites all cause allergic responses in cats. Whether your cat’s eyes are bothered by something in the air or they’re coping with a bug issue, they may scratch their eyes frequently. A stye may develop when the skin surrounding their eyes breaks and bacteria forms. 


Trauma may also irritate your cat’s eye and cause a stye to emerge. This might be caused by your cat being smacked in the eye, getting into a fight with another cat, or anything else that breaks the skin surrounding the eyelid. Bacteria may grow within the rip when the skin breaks, resulting in a stye.


Acute infections of any sort are a typical side effect of diabetes because it impairs the immune system. Human and feline eyelids are equally vulnerable to infections that may lead to the formation of a stye. 

What happens if you don’t treat a stye?

Will my cat’s eye infection go away on its own? This is a common question among pet owners. The explanation is that styes are a form of illness that usually resolves on its own. However, it’s possible that your cat may continue to scratch the damaged region, causing more irritation. If left untreated, a stye may develop infectious and spread throughout the eye. If the infection spreads to the eye, it may cause your cat to lose partial vision or perhaps become blind in the affected eye if left untreated. 

What is the best way to treat a stye?

Keep your cat’s eyes clean if you find they have a stye. The procedure for cleaning cat eye discharge is rather straightforward! All you have to do is gently wipe away the discharge with a wet cotton ball. 

A warm compress may also make your cat’s eye feel better. Warm a washcloth and gently massage it against your cat’s eyelids—but make sure the water isn’t too hot. Unless otherwise directed by your veterinarian, never use over-the-counter eye drops on your cat.

Assist in keeping your cat healthy.

Keeping a cat’s optic health in check is a priority for every pet parent, from the way cats view the world to the wonderful brilliant hues of their eyes! Preventive precautions should be taken, and eye issues should be addressed as soon as they arise. Keep in mind that your cat’s visual problems might indicate an underlying medical concern. Take your cat to the vet if you’re unsure.

Why do my cat’s eyes continually getting infected?

Because kittens’ immune systems are weaker, they are more vulnerable to eye infections. The feline herpes virus may cause severe conjunctivitis in your cat. A cat’s eye infection might also be caused by autoimmune illness, malignancy, ocular damage, or feline leukemia.

Is it possible for cat eye diseases to transmit to humans?

Eye infections in cats are caused by viruses and bacteria that cannot be passed to humans.

Is it possible to cure feline eye infections at home?

While there are some home remedies that may help relieve the discomfort caused by cat eye infections, it’s better to see your veterinarian so that your pet can get the right diagnosis and treatment.
