How Can You Tell If Your Cat Has An Eye Infection?

Recognizing the Symptoms

Eye infections in cats are common and curable if you recognize the symptoms and can act promptly. Early treatment not only relieves your cat’s discomfort but can also prevent more serious complications down the road.

If you notice your cat squinting, showing irritation, or producing abnormal discharge from his or her eyes, it’s possible that they might have an eye infection. 

Here’s what you need to know to recognize the signs of an eye infection, what causes them, and when it’s important to seek veterinary care.

Signs Your Cat May Have an Eye Infection

Red or Swollen Eyes:

One of the first indicators of an eye infection in cats is redness in the affected eye or eyes. Infections often cause inflammation, which leads to a pinkish or red hue around the inner eyelids. Swelling may also occur, making the eye look puffier than usual. If your cat’s eye appears irritated or more swollen than normal, this could be a sign of an underlying infection.

Discharge and Tear Production:

Excessive tearing or abnormal discharge is another common sign of eye infections. While it’s normal for cats to occasionally have a bit of clear discharge, thick, yellow, green, or white discharge indicates infection. Cats with infected eyes may produce more tears than usual or have crusty build-up around the eyes.

Squinting or Keeping the Eye Closed:

Eye infections can cause discomfort or pain, and you may notice your cat squinting or even keeping one eye closed. This is often a cat’s way of protecting the eye, as opening it may cause pain due to irritation or light sensitivity. Persistent squinting is a red flag for potential infection or other eye-related issues.

Pawing or Rubbing the Infected Eye:

Cats with eye infections may try to relieve their discomfort by pawing at or rubbing the infected eye. This action can cause further irritation or introduce more bacteria, worsening the infection. If your cat seems overly focused on scratching or rubbing their eye area, it’s best to keep an eye on this behavior and seek veterinary advice if it continues.

Cloudiness in the Infected Eye

In more severe cases, eye infections can lead to a cloudy or hazy appearance in the affected eye. Cloudiness might also be accompanied by changes in the size or shape of the pupil. Although not as common, this symptom should be treated as an emergency, as it could signal a deeper infection or damage to the eye’s inner structures.

Behavioral Changes:

Cats are known to mask their pain well, but eye infections can make them noticeably less playful or more withdrawn than usual. They may hide, avoid bright light, or seem more sensitive to touch around the face and eyes. Changes in behavior, coupled with any of the other symptoms mentioned, often indicate that your cat may be struggling with eye discomfort or infection.

What Are the Common Causes of Eye Infections in Cats?

Several factors can lead to eye infections in cats, ranging from bacterial and viral infections to physical irritants or injuries.

Viral Infections:

The feline herpesvirus is one of the leading causes of eye infections in cats. Many cats carry this virus without any symptoms, but stress or other illnesses can trigger an outbreak, leading to conjunctivitis or other eye issues.

Bacterial Infections:

Secondary bacterial infections often occur when an eye is already irritated. For instance, a cat with an existing scratch or irritant in the eye might develop a bacterial infection, which can worsen the symptoms.

Foreign Bodies or Allergens:

Dirt, dust, or even a strand of fur in the eye can cause irritation that, if left untreated, may lead to an infection. Cats can also experience eye issues related to seasonal or environmental allergies.

Injuries or Scratches:

Cats are curious creatures, and sometimes their explorations or interactions with other animals lead to scratches or minor injuries to the eye. These injuries create an opportunity for bacteria to enter and cause an infection.

When to Seek Veterinary Care

While some mild cases of eye irritation may resolve on their own, it’s important to consult your veterinarian if you notice any of the symptoms listed above persisting or worsening. Untreated eye infections can lead to more severe issues, including corneal ulcers or even loss of vision.

When to prioritize a vet visit:

Below are some symptoms that, if occurring, should indicate that it’s time to see your vet:

Persistent Symptoms:

If symptoms like discharge, redness, or swelling last more than a day or two, it’s best to have your vet examine your cat.

Increasing Discomfort:

Rubbing, pawing, or signs of pain in your cat are signs that their discomfort may require medical intervention.

Cloudiness or Pupil Changes:

These are often more serious symptoms that need immediate attention to prevent long-term damage.

Treatment Options for Eye Infections in Cats

After a diagnosis, your veterinarian may prescribe one or more treatments to help your cat recover.

Below are some of the different options to help treat your cat’s eye infection:

Medicated Eye Drops or Ointments:

Antibiotics or antiviral eye drops are commonly prescribed to clear up bacterial or viral infections. It’s crucial to apply these exactly as prescribed to ensure the infection clears up fully.

Oral Medications:

In some cases, oral antibiotics or anti-inflammatory medications may be necessary, especially if the infection is severe or has spread beyond the eye.

Home Care:

Gently wiping away your cat’s eye discharge with a damp, clean cloth can help keep your cat’s eye area clean and comfortable. Avoid using anything that might irritate your cat’s eyes such as rough fabrics or cleaning solutions.

Tips to Prevent Future Eye Infections

While not all infections are preventable, there are steps you can take to reduce the risk:

Keep Your Cat’s Environment Clean:

Dust-free, clean living areas help prevent irritants from affecting your cat’s eyes.

Regular Vet Check-Ups:

Routine veterinary exams can help catch early signs of eye conditions or infections.

Limit Exposure to Sick Pets:

If possible, avoid letting your cat interact with other pets in your home that are showing signs of illness, as some infections are contagious.

It can be very helpful to know the signs of an eye infection as it can help you take prompt action and provide comfort for your cat. If you spot red flags such as swelling, discharge, or squinting, don’t hesitate to talk to your veterinarian.

By staying attentive, you can make sure that your cat’s eyes remain clear, healthy, and infection-free.
