Introduction
Epiphora is the medical term for excessive tearing or watery eyes in cats, a condition that may seem minor but can signal underlying health issues. While occasional tearing can be normal, persistent or heavy discharge often indicates irritation, infection, blocked tear ducts, or even more serious eye problems. Ignoring watery eyes can lead to discomfort, secondary infections, or vision impairment. Recognising and addressing the signs early ensures your cat stays healthy, comfortable, and free from unnecessary pain.
What Is Epiphora in Cats?
Epiphora in cats is a condition where tears overflow from a cat’s eyes due to either overproduction of tears or an inability to drain them properly. Normally, tears are produced to keep the eyes moist and healthy, and they drain through small ducts into the nasal cavity. However, when this drainage system is blocked, it leads to constant tearing and visible wetness around the eyes.
It’s important to differentiate between normal eye watering, such as minor tearing from dust or wind, and excessive or persistent epiphora, which may be a sign of an underlying issue like infection, injury, or structural abnormalities. Left untreated, epiphora can cause skin irritation, staining, and discomfort for your cat.
Reasons Why Your Cat’s Eye is Watering
If you're wondering, “why is my cat’s eye watering?”, there are several possible causes. Common reasons include allergies (such as pollen or dust), exposure to irritants like smoke or strong chemicals, blocked tear ducts, eye infections (like conjunctivitis), or even foreign bodies such as a piece of dust or hair caught in the eye. In some cases, watery eyes may also be related to underlying health conditions or anatomical issues, especially in flat-faced breeds.
Cat Has One Watery Eye and No Other Symptoms – Should You Worry?
It’s important to note the difference between one eye and both eyes watering. If only one eye keeps watering, it may indicate a localized issue such as an injury or blockage. In contrast, both eyes watering often points to environmental allergies, systemic illness, or widespread irritation. Persistent tearing in either case should be evaluated by a veterinarian to identify and treat the underlying cause effectively.
A single watery eye can result from a minor irritant, such as dust or a hair, or a mild blockage in the tear duct. In many cases, it clears up on its own within a day or two.
However, it’s important to monitor for early signs of something more serious—like redness, swelling, discharge, excessive blinking, or your cat pawing at the eye. If any of these symptoms appear, or if the tearing persists for more than a couple of days, it’s best to consult your vet. Prompt attention can help prevent a minor issue from developing into a more serious eye condition.
Associated Symptoms to Watch Out For
While watery eyes may seem harmless, certain associated symptoms can indicate a more serious issue. If you notice yellow discharge from your cat’s eye, it could point to a bacterial infection like conjunctivitis. Other warning signs include redness, squinting, swelling, and your cat pawing at the eye—all of which suggest pain or irritation that needs veterinary attention.
In rare cases, you may wonder, “can watery eyes be a symptom of cancer?” Though uncommon, certain types of eye tumors or cancers can cause persistent tearing, especially if they affect tear drainage or pressure around the eye. That’s why it’s important to take any prolonged or unusual eye symptoms seriously and have your vet evaluate them promptly. Early diagnosis is key to effective treatment and protecting your cat’s vision and overall health.
Epiphora Treatment in Cats
Effective epiphora treatment in cats depends on the underlying cause of the excessive tearing. For mild cases or temporary irritation, at-home care can help—gently clean the area around the eyes with a soft, damp cloth to remove tear stains and prevent skin irritation. Using pet-safe eye wipes can also keep the area hygienic and comfortable.
However, if the tearing persists or is accompanied by discharge, redness, or swelling, veterinary care is essential. A vet may prescribe antibiotics for infections or recommend procedures like tear duct flushing if there’s a blockage. In more serious cases, such as anatomical issues or chronic infections, further medical or surgical interventions may be necessary. Early and appropriate treatment helps manage symptoms and protects your cat’s eye health long-term.
Best Eye Drops & Medicine for Watery Eyes in Cats
When it comes to watery eyes treatment over the counter, there are a few safe options available in the UK, but it's crucial to use them only with veterinary guidance. Some over-the-counter eye drops for cats, such as saline-based solutions, can help flush out irritants and soothe minor eye issues. However, these should never be used as a substitute for proper diagnosis.
For more serious or persistent symptoms, your vet may prescribe the best eye drops for cats, such as antibiotic drops (e.g., fusidic acid gel) for infections or anti-inflammatory medications to reduce irritation. If you're wondering what is the best medicine for watery eyes, it will ultimately depend on the root cause—whether it’s an infection, allergy, or blocked tear duct. Always follow your vet’s instructions closely regarding dosage and application to ensure your cat's safety and comfort.
You can also use Lubrithal Dog & Cat Eye Gel goes beyond basic moisture. Unlike typical eye drops that simply wet the cornea, Lubrithal uses advanced carbomer technology to lock in hydration and maintain a healthy tear film for longer-lasting relief.
Pro tip: Never use human eye drops or unapproved treatments, as these can cause more harm than good. The safest approach is to get a proper diagnosis and use vet-recommended eye drops to stop watery eyes effectively.
Conclusion
Watery eyes (epiphora) in cats can range from a mild inconvenience to a sign of something more serious. Early detection is key—look out for yellow discharge, redness, squinting, or persistent tearing. Simple at-home care may help in mild cases, but veterinary treatment is crucial for infections, blockages, or recurring symptoms. If you're ever in doubt, it’s best to consult your vet early. Prompt attention ensures your feline friend stays healthy, comfortable, and free from eye-related complications.
