What Causes Eye Discharge Or Drainage In Cats?

What Causes Eye Discharge Or Drainage In Cats?

Before we begin let’s first take a look at today’s topic overview.

Elderly cats have high discharge due to viral infections such as feline herpesvirus 1 (FHV-1) and bacterial infections such as feline infectious anaemia (FIA). Other common causes of leaky, watery eyes and cats include allergies, injuries, parasites and fungal diseases.

Common Causes Of Weeping Eyes

Concerning about today’s topic i.e what causes eye discharge or drainage in cats? The causes of weeping eyes and drainage can potentially lead to larger issues. Some triggers that could seem harmless can unfortunately become at least at times symptoms of a much greater concern.

Here are some of the most notable causes of weeping eyes in felines.

Viral diseases such as feline herpes virus one or feline Khaleesi virus, systemic bacterial diseases such as feline infectious anaemia, systemic fungal diseases such as feline blastomycosis, a localized fungal or bacterial infection inside of the eye, dust dirt or cat fur aggravating the eye, injury, allergies, dust mites, flea bites, grass pollen, fragrances, foods such as beef and fish, irritants such as the wind or foreign objects, tear canal problems and parasites such as the disease known as toxoplasmosis.

And as we mentioned any collection of the aforementioned symptoms or causes can lead to the following issues.


Conjunctivitis is commonly known as pink eye. It’s an inflammation of the conjunctiva. This is the peak membrane that surrounds the white of the eye and serves to line the inside of the eyelids. Pink eye can cause discharge, squinting and redness.

And on a personal note, I had pink eyes some 20 years ago it was not a fun ride of this I can tell you.


The next issue is epiphora. Commonly known as the standard watery eyes.

Many of the causes we noted a bit earlier can usher in this very problem, just too many tears. That’s the most basic way to describe it. And just like pink eye, I’m sure there are many people watching that have overactive tears due to a variety of irritants, pollen, changes in the weather, eye strain from looking at your phone or computer for just too long. When it comes to your cat this can turn into a mess.

Wet and drippy eyes in some cases the fur directly underneath the eyes will stain and another common cause of weeping eyes.


The final one that we’ll speak about in this subsection is keratitis or more commonly known as an irritation or inflammation of the cornea, which is the dome-shaped layer of protection in front of the eye. Keratitis can cause the cornea to appear rough and damaged. The result is often some level of weeping and discharge from the eye.

Here again, keratitis can impact both humans and felines alike. And just to put a nice bow on things the three most common causes of eye weeping and felines are based on a symptom collective, standard allergies irritants, dust, debris and even injury.

It’s important to note that not every cause is based on an external factor that directly impacts the eye and the eye alone. Sometimes weeping and drainage is the result of an infection such as a virus or another form of contagious disease that can impact the body as a whole.

Signs Of Infection

What Causes Eye Discharge Or Drainage In Cats?

If your feline has contracted a virus or contagious disease we encourage you to be mindful of the following symptoms. The discharge is colored yellow or green rather than clear. The discharge has a mucus-like texture rather than a watery texture.

The discharge is in both eyes and the cat has flu-like symptoms. While many infections of the body can create side effects that negatively impact the eyes.

There are four diseases that are somewhat regular players in this game.

1. FHV-1

We’ll begin with the feline herpes virus one also known as fhv1. Many felines will contract fhv1 at some point in their lives, remaining dormant in the body for years.

Once the virus flares up it can create flu-like symptoms that eye discharge stress and anxiety of all things. Often the trigger releases the virus from its dormant dwelling.

2. Feline Khaleesi Virus

Another troublesome virus that we’ll note today is the feline Khaleesi virus also known as FCV. It can trigger an upper respiratory infection in addition to runny and inflamed eyes.

Symptoms such as sneezing, coughing gasping for air, runny nose lethargy, limping and reduced appetite are common.

Fcv must be treated in the early stages due to the fact that felines can often acquire secondary bacterial infections.

They could become quite aggressive and very serious.


Our next concern which is chlamydia, more commonly known as feline chlamydia.

Unlike many other conditions cats with feline chlamydia, typically do not display flu-like symptoms. However, a thick mucus in both eyes is very common.

Feline Infectious Anemia

Final disease or the virus that we’ll discuss today is feline infectious anaemia or FIA.

This is a bacterial disease caused by a collection of mycoplasmas or specialized bacterias that pass between animals and leech off their blood.

FIA can cause pink eye weight loss, lethargy and fever.

This blood disease is extremely serious and can be fatal if not treated.

How Do Contagious Diseases Spread Between Cats?

What Causes Eye Discharge Or Drainage In Cats?

And since, we are on the subject of contagious diseases more specifically medical issues that impact the eyes and lead to discharge and drainage.

How exactly are these diseases transmitted?

It should come as no surprise that felines that go outdoors on a regular basis or cats that live with other pets are at a much greater risk. Infectious diseases can pass between animals in the following notable ways.

The sharing of water and or food bowls, licking and grooming each other, sharing a litter box or going to the toilet in the same patch of earth (obviously referring to the outdoors), Close of physical contact or as we would call it in current times a lack of social distancing and lastly shared betting.

Speaking to this subtopic as a whole and everything we’ve covered thus far, if your feline has runny eyes you should isolate them from the other animals within your home until you’ve had a chance to schedule a vet visit.

What Is Uveitis?

Another eye condition that certainly deserves our time today is uveitis.

When the internal portion of the eye known as the uveal tract becomes inflamed, the result can be quite serious and potentially lead to blindness if left untreated. Squinting attempting to rub or pull with an eye. The third eyelid becoming visible and the appearance of a cloudy eye and redness of the eye are the most common symptoms.

It should also be said that corneal ulcers mentioned earlier can develop and turn into uveitis. In many cases, the primary cause of uveitis is a systemic disease such as a feline herpes virus one, a fungal disease or a parasite.

How Is Eye Discharge Treated?

When it comes to the proper treatment your vet, will determine if the discharge is caused by a systemic infection, injury, allergy, irritant or something else and then recommend a suitable treatment.

This may include oral antibiotics, antiviral medication, eye drops, surgery to unblock the tear canals and keeping your eyes clean through the means of cotton pads to dab the eyes. And vaccinations contagious disease prevention against the herpes virus and Khaleesi virus.

It’s important to separate your cat from the other animals in your home during the healing process. Thankfully most conditions that trigger eye discharge and drainage can be cleared within two to three weeks with the proper treatment.

Final Words from Me

Love is essential in every aspect. There is a power in love that can treat small or big diseases easily with the help of proper medication. For me, proper medication and love both lie on the same page.

I know you love your cats that’s why you came here. Consult or go to the vet if you find something disturbing your cats.
