Seeing your beloved cat with eye discharge, constant tearing, or eyes so gummy they are hard to open is understandably worrying. The good news is that many cases of watery eyes in cats are mild and improve with gentle care. But some are a sign of an infection or a problem that needs a vet. This article helps you calmly tell the difference.
- Eye discharge and watery eyes in cats are most often caused by cat flu, infection, or irritation.
- Home care is mostly about gently cleaning with warm water, not applying human eye drops.
- See a vet right away if your cat squints, the eye looks cloudy, the discharge is green or yellow, or it stops eating.
- Kittens with eye problems always need to be checked sooner.
Why cats get eye discharge and watery eyes
A healthy cat eye is usually clean, clear, and fully open with no excess fluid. When discharge or constant tearing appears, it is a signal that something is bothering the eye. Here are the causes we see most often.
1. Cat flu (upper respiratory infection)
This is the number one cause, especially in kittens and cats living in crowded settings or newly adopted. Cat flu is usually caused by viruses (most commonly herpesvirus and calicivirus) and often comes with sneezing, a runny nose, watery eyes, and eyes that gradually become gunky. The cat may look listless and off its food. Feline herpesvirus also tends to flare up when a cat is stressed, for example after moving house or the arrival of a new pet.
2. Eye infection (conjunctivitis)
Conjunctivitis is inflammation of the pink membrane around the eye. Besides flu viruses, it can be triggered by certain bacteria. Signs include a red eye, swollen eyelids, tearing, and discharge that grows thicker. If the discharge is yellow or greenish, that is a strong clue of an infection that needs a vet, not just cleaning at home.
3. Irritation and foreign objects
Dust, cigarette smoke, perfume, strong-smelling cleaning products, shampoo that gets in during a bath, or a stray hair stuck to the surface can make a cat eye water as a normal reaction. Sometimes a small object like sand or a bit of grass gets lodged behind the eyelid and makes the cat uncomfortable. Mild irritation usually improves on its own once the trigger is gone, but if the cat keeps rubbing or squinting, do not ignore it.
4. Other causes that need checking
There are also causes that are not always obvious from the outside, such as a wound or scratch on the surface of the eye (cornea) from a claw or scratching, a blocked tear duct that lets tears overflow onto the cheek, or allergies. In flat-faced breeds like Persians and Himalayans, watery eyes are more common because of their face shape, but it still needs to be confirmed that nothing else is wrong. These causes are hard to tell apart without a direct examination.
Warning signs you should not delay on
Most mild watery eyes can be monitored at home for a day or two. But some signs point to a more serious situation and should be seen by a vet soon:
- The cat squints or keeps one eye closed continuously. This often signals pain, and a painful eye is a condition that needs prompt care.
- The surface of the eye looks cloudy, hazy, or foggy, or there is a white patch or unusual colour on the eyeball.
- Discharge that is yellow, greenish, or very thick, especially if the eyelids stick shut.
- The eyelid or the area around the eye is swollen, or a membrane appears covering part of the eye (the third eyelid).
- The cat keeps scratching or rubbing its eye on the floor and furniture. Scratching can worsen a wound on the eye surface.
- The eye problem comes with other symptoms such as refusing food, weakness, fever, heavy sneezing, or trouble breathing.
For kittens, the threshold for concern should be lower. Kittens with eye discharge can worsen quickly, and in severe cases a gummy eye can even seal shut before it has a chance to open. Do not wait too long, it is better to have it checked early.
What you can do at home
For mild watery eyes without the warning signs above, this gentle care is safe to do while you monitor how things develop:
- Clean the discharge gently. Dampen a cotton pad or clean cloth with warm boiled water, then wipe gently from the inner corner of the eye outward. Use a fresh piece for each eye so you do not transfer germs from one to the other.
- Keep the face dry and clean after cleaning, so it does not become damp and gummy again.
- Reduce irritation triggers around your cat, such as cigarette smoke, dust, and the sharp smell of cleaning products.
- Limit stress and let the cat rest. For a cat suspected of having flu, rest and a calm environment help recovery.
- Temporarily separate from other cats if you have more than one, because cat flu and some eye infections can be contagious.
There are also things you should avoid. Do not use human eye drops or leftover medicine from another cat, because some ingredients can be dangerous to a cat eye and actually make things worse. Do not try to dig out a foreign object yourself with a hard implement, and do not hold off too long if symptoms do not improve. Choosing the right eye medicine for a cat needs to be matched to the cause by a vet after an examination.
When to call a vet or head to a clinic
Contact a vet right away if you see any of the warning signs above, if symptoms do not improve within a day or two of gentle care, or if your cat seems to be in pain. Conditions like a very painful eye, a suddenly cloudy eye surface, an eye injury, or an eye that looks like it is bulging are situations that should not wait, and for emergencies outside normal hours it is best to head to the nearest animal clinic offering 24-hour service.
A calm eye examination is often more accurate when done at home, in the place where your cat is most comfortable, without the stress of travel and a waiting room that leaves it tense. A Prabasa Vet vet can come directly to your home to examine your cat eye, find the cause, and prepare suitable treatment. If you are unsure whether your cat needs to be seen today or can simply be monitored first, you do not have to guess on your own.

Notes & references
This article is educational and general in nature, and does not replace a direct examination by the vet handling your cat. The causes and signs mentioned refer to common symptoms of eye disease and upper respiratory infection in cats. The choice of medication, including eye drops or ointment, must be decided by a vet according to the cause, because some human medicines can harm a cat eye. A painful eye, a suddenly cloudy eye, or an injury are conditions that should not be delayed.
