To prevent the possibility of vision loss and further complications, it is crucial to follow your veterinarian’s instructions regarding the appropriate use of medications, dosage, and duration of treatment. Your veterinarian may also provide additional recommendations to manage your cat’s conjunctivitis effectively, such as eye drops or ointments to alleviate discomfort and help clear any discharge.

Regular follow-up visits will ensure proper monitoring of your cat’s progress. Preventing feline conjunctivitis can be challenging, given its various causes.

However, maintaining good hygiene practices for your cat is a fundamental step in minimizing the risk. Keep your cat’s living area clean and remove potential irritants like dust, smoke, or pollen.

Avoid exposing your cat to other infected cats or environments where the risk of viral or bacterial transmission is high.

Upper Respiratory Infections as a Cause of Watery Eyes in Cats

Viruses Causing Upper Respiratory Infections in Cats

Watery eyes in cats can also be attributed to upper respiratory infections (URIs), commonly caused by viruses such as feline herpesvirus (FHV) and calicivirus. These viruses spread easily among cats, particularly in crowded or stressed environments, such as shelters or multi-cat households.

Chlamydophila felis and bordetella bronchiseptica are two other bacteria that can cause URIs in cats. FHV, the most common viral cause of URIs in cats, can lead to conjunctivitis, along with other symptoms such as sneezing, nasal discharge, coughing, and ulcers on the tongue and lips.

Calicivirus primarily affects the respiratory tract, resulting in symptoms like ulcers in the mouth, sneezing, and nasal discharge. Chlamydophila felis often causes conjunctivitis, while bordetella bronchiseptica primarily affects the upper respiratory system, leading to coughing and sneezing.

Treatment and Vaccination for Upper Respiratory Infections in Cats

Treating URIs in cats requires professional veterinary care. Depending on the severity of the infection and the specific pathogens involved, treatment may include antibiotics to combat accompanying bacterial infections and antiviral medications to alleviate symptoms caused by viral infections.

Anti-inflammatory medications can help reduce swelling and discomfort. In some cases, eye drops may be prescribed to address conjunctivitis and alleviate watery eyes.

Preventive measures play a crucial role in managing URIs. Vaccination is key to protecting cats against certain viral pathogens, such as FHV and calicivirus. Regular vaccination, starting from kittenhood, can significantly reduce the severity and duration of URIs. Vaccines are available that specifically target these viruses, and your veterinarian can recommend an appropriate vaccination schedule.

In addition to vaccination, practicing good hygiene and minimizing stress can help prevent the transmission of URI-causing viruses. Ensure your cat’s living environment is clean and properly ventilated.

Regularly clean food and water bowls, litter boxes, and bedding. It is also advisable to isolate sick cats to prevent the spread of infections within multi-cat households.


Understanding the causes and symptoms of watery eyes in cats, including feline conjunctivitis and upper respiratory infections, enables us to provide timely care and avert potential complications. Prompt veterinary evaluation, proper treatment, and preventive measures, such as vaccinations and hygiene maintenance, are essential for safeguarding our feline companions’ ocular and respiratory health.

By remaining proactive and vigilant, we can ensure our cats live happy, healthy lives, free from the discomfort of watery eyes and respiratory infections.

Other Causes of Watery Eyes in Cats

Eye Injuries and Trauma as Causes of Watery Eyes in Cats

While allergies, infections, and respiratory conditions are common causes of watery eyes in cats, eye injuries or trauma can also result in excessive tearing. Inflammation, redness, and watering are typical symptoms that may accompany eye injuries.

Cats may experience foreign bodies, dirt, or sand getting into their eyes, leading to irritation and tearing. Scratches on the cornea or inner structures of the eye can cause discomfort and watery eyes as well.

Additionally, grass awns, small plant structures, can become lodged in the eye, leading to inflammation and excessive tearing. If you suspect your cat has suffered an eye injury or trauma, it is essential to seek immediate veterinary attention.

Your veterinarian will thoroughly examine your cat’s eye and may perform specialized tests to assess the extent of the injury. Treatment options will depend on the nature of the injury and may include topical medications to reduce inflammation and promote healing.

In severe cases, surgery may be necessary to repair any damage to the eye structures.

Epiphora and Blocked Tear Ducts as Causes of Watery Eyes in Cats

Epiphora is a condition characterized by excessive tearing or watery eyes. Blocked tear ducts are a common cause of epiphora in cats.

Tears normally drain through tiny tubes called tear ducts, which connect the eyes to the nasal cavity. When these tear ducts become blocked or narrow, tears cannot properly drain away, leading to watery eyes.

Blocked tear ducts in cats can be congenital or acquired. Congenital blockages are present from birth and are often associated with abnormalities in tear duct development.

Acquired blockages can occur due to inflammation, infections, or trauma to the tear ducts. Epiphora caused by blocked tear ducts can result in persistent tearing and may lead to staining of the fur around the eyes.

If your cat is experiencing epiphora, it is important to seek veterinary evaluation. Your veterinarian may recommend flushing the tear ducts to remove any blockages or may consider surgical intervention to correct the underlying issue.

Flushing the tear ducts is a common procedure that involves using a specialized solution to clear the blockage and restore normal tear drainage. Surgery may be required if other treatments are unsuccessful or if there is a structural abnormality causing the blockage.

It is important to note that both flushing and surgical procedures may require anesthesia to ensure the comfort and safety of your cat.

Treatment and Management of Watery Eyes in Cats

Treatment Options for Watery Eyes in Cats

Determining the appropriate treatment for watery eyes in cats depends on the underlying cause. In cases of allergies, infections, or inflammations, your veterinarian may prescribe eye drops or ointments to alleviate symptoms and combat the underlying issue.

Depending on the severity of the condition, additional treatments, such as oral antibiotics or anti-inflammatory medications, may be necessary. In situations where structural abnormalities, such as blocked tear ducts or eye injuries, are responsible for watery eyes, treatment options may vary.

Flushing the tear ducts is a common approach to clear blockages and restore normal tear drainage. Surgical intervention may be considered for more complex issues, such as repairing damaged eye structures or correcting congenital abnormalities.

It is crucial to closely follow your veterinarian’s instructions regarding post-treatment care and medication administration.

Risk Factors and Outlook for Watery Eyes in Cats

Certain cat breeds are more prone to watery eyes due to their unique facial structures. Breeds with short muzzles and prominent eyes, such as Persians, Exotics, and Himalayans, often experience watery eyes.

The flattened face shape and nose structure in these breeds can lead to a narrower tear duct, making them more susceptible to tear drainage issues. Preventive care plays a crucial role in managing watery eyes in cats.

Regular veterinary checkups allow for early detection of any potential issues and ensure prompt intervention. Vaccinations can help protect against infectious causes of watery eyes, such as feline herpesvirus and calicivirus.
