There are a lot of reasons for cat eyes watering. A small amount of discharge or ‘crust’ is normal at the corner of a cat’s eyes, but if you start to notice constant weeping discharge or a sticky, yellow goop, these may be a cause for concern.
Watery eyes are also known as epiphora and can occur due to a range of factors, from the overproduction of tears or allergies to infections or something stuck in your pet’s eye.
What Does It Mean If A Cat’s Eyes Are Watering?
There are a lot of reasons your kitty’s eyes may be weeping, and while some reasons are harmless, it’s always important to find out why this is happening to your pet’s eyes in case there is a more sinister underlying cause.
A cat’s eyes should be bright and clear. You should be able to clearly see their pupil (black) and iris (colored) parts.
If you notice the occasional clear-colored, watery discharge from your pet’s eye it may not be anything to worry about but if it recurs regularly, persists, or if the discharge becomes yellow or sticky then there may be a cause for concern. Other signs that your cat’s eyes may be bothering them include cloudiness to their eye, pawing at their face, or excessively blinking or squinting.
Causes Of Watery Eyes In Cats
Some of the common causes of watery eyes in our feline friends include:
Upper Respiratory Infections
Upper respiratory infections in cats including cat flu cause snotty noses and weepy eyes alongside general feelings of lethargy and malaise in pets. Infections tend to be viral but can also be bacterial which can lead to life-threatening pneumonia if untreated.
These include scratches or ulcers on the surface of a kitty’s eye. These are incredibly painful and need treatment immediately to prevent further damage to the eye that may require surgery.
Blocked Tear Ducts
There are many things that could cause your kitty’s tear ducts to become blocked but the most common tend to be dust or mucus. Tears can’t drain properly from your pet’s eyes when these ducts are blocked and lead to what appear to be weepy, wet eyes and face.
The most common foreign body in eyes tend to be grass seeds, particularly in late summer and fall. These tend to get trapped underneath the third eyelid causing irritation which leads to increased tear production. Entropion (turned-in eyelashes) can also act as foreign bodies and irritate a pet’s eyes.
Conjunctivitis (Bacterial or Viral)
Conjunctivitis is inflammation of the pink mucosa surrounding a cat’s eyes and tends to make the eyes appear swollen and reddened. The discharge associated with this can be clear and watery or thick and yellow if there is a bacterial infection.
As with humans, pet cats can be allergic to a range of things including dust and pollens and weepy eyes may be a sign of such an allergy. Some felines with these allergies may also appear itchy or groom excessively.
Commonly described as “dry eye”, this condition is associated with underproduction of the natural tear film on the eyes. This means your cat’s eyes aren’t being lubricated appropriately and dust isn’t being “washed” away in tears. If untreated, dry eye can lead to blindness and pet’s suffering from this condition tend to blink excessively and have a thick, yellow discharge from their eyes.
Some breeds of cat are predisposed to eye problems with brachycephalic (flat-faced) breeds being some of the most affected. Persians and British Shorthair cats commonly have weepy eyes and tear-stained faces due in part to their skull shape and bulbous appearance to their eyes.
What To Do If Your Cat’s Eyes Are Watering?
So you’ve just noticed your kitty’s eyes are looking a little weepy, the next thing to do is look for signs of pain (squinting or pawing their face), redness or cloudiness to the eye and it’s surrounding tissues.
If you think there is any bulging or swelling to your pet’s eye or if there are other symptoms including sneezing or fever then you should contact your veterinarian immediately.
If your pet is acting completely normally and has only a mild discharge that has just started, you can monitor them for a few hours. You can also gently wipe away the tears with a cotton pad to determine if the discharge persists as some pet’s can develop weepy eyes if they have gotten a speck of dirt in their eye that is washed away and are fine within a short time.
Treatment For Watery Eyes In Cats
Treatment for ocular discharge in kitties will depend on the underlying cause of the weepy eye. If your kitty is in pain and has a bacterial infection then your veterinarian will prescribe antibiotic eye medications and some pain relief. If your cat is also ill with a fever or respiratory infection then fluid therapy and decongestant medications may also be required.
Conjunctivitis may be treated with ointment or drops that contain steroids to reduce inflammation. However, if your pet has a corneal ulcer then these ointments can actually make their eye worse so your veterinarian will always examine your pet’s eye first before prescribing any medications. In some corneal injuries, your pet may actually need surgery to remove dead tissue, though thankfully this is uncommon.
Blocked tear ducts tend to be treated under sedation or a general anaesthetic as your veterinarian will need to insert a catheter into the duct and flush sterile saline through to remove the blockage. Other problems such as dry eye or allergies may require daily, long term therapy with artificial tears, steroid or immune-suppressing medications.
The key information is that eyes are incredibly delicate, easily damaged and if left without treatment, many of the causes of watery eyes can eventually lead to blindness or requiring surgical removal of the affected eye (enucleation). If you’re ever concerned about your pet’s eye, contact your veterinarian for advice to prevent further damage to their eye.
Frequently Asked Questions
What does it mean when your cat's eye is watering?
Eyes tend to 'water' when there is some form of inflammation. This may be a tiny particle of dust entering the eye that is rapidly washed away by your cat's natural tear production or can indicate something more serious such as infection or trauma to the surface of the eye.
How do you treat watery eyes in cats?
Treatment for watery eyes depends on the underlying cause of the discharge. Your veterinarian will give your kitty a full examination to ascertain the problem before starting any treatment. This is because some treatments may actually make certain conditions worse if used inappropriately.
Is it bad if my cat's eye is watering?
This depends on how long and what type of discharge your cat has. If it's temporary and not associated with pain or other signs then it's most likely nothing to worry about. If, however, you notice that your cat develops a yellow, thick discharge, seems painful, has other signs or the discharge persists then you need to make an appointment with your veterinarian to have your kitty checked out.
Will cat conjunctivitis go away by itself?
Sadly, no. Conjunctivitis is inflammation of the delicate pinkish tissues around your feline friend's eyes and can be caused by a number of factors, including allergies, infections, or a foreign body trapped underneath. All of these require treatment to alleviate your pet's irritation and prevent permanent damage from being done to your kitty's eye.
