Observing your cat’s eyes can tell you a lot about their health. A healthy cat’s eye should be clear and bright. The eye’s outer layer naturally produces moisture to protect it from dust and irritants. However, if you’ve noticed your cat’s eye watering excessively, or if they are squinting, it’s a signal that something might be amiss. While sometimes it can be a minor issue that resolves on its own, persistent or worsening watery eyes in cats can indicate a more serious underlying condition that requires attention. Let’s explore the common reasons behind why your cat’s eye might be watering and when it’s crucial to seek veterinary advice.
Common Causes of Watery Eyes in Cats
When a cat experiences watery eyes, it’s often the body’s natural response to combat irritation or infection. The increased tear production is an attempt to flush out potential threats. While some causes are benign and temporary, others require veterinary intervention. To understand the reason behind your cat’s watery eyes, it’s important to observe any accompanying symptoms.
Allergies
Just like humans, cats can suffer from allergies that manifest in various ways, including watery eyes. Allergens can irritate the eyes, causing them to produce more tears as a defense mechanism. Common culprits for feline allergies include:
- Pollen: Seasonal allergies can affect cats, just like people.
- Mold and Mildew: These common household allergens can trigger eye irritation.
- Dust mites: Found in bedding and carpets, dust mites are a frequent allergen.
- Household cleaning products: Strong chemicals can irritate sensitive eyes.
- Perfumes and fragrances: Airborne scents can cause allergic reactions in some cats.
- Certain medications: In rare cases, drug reactions can include watery eyes.
If you suspect allergies, try to identify and remove potential allergens from your cat’s environment. If the watery eyes persist or you can’t pinpoint the cause, a veterinary visit is recommended to rule out other issues and potentially manage allergy symptoms.
Foreign Bodies and Blocked Tear Ducts
If your cat’s watery eye is accompanied by excessive blinking, squinting, or pawing at their face, there might be a foreign object irritating their eye. Debris like dust, dirt, or even a stray eyelash can get lodged in the eye and cause discomfort and increased tear production.
Another possible cause, though less common in cats than in dogs, is a blocked nasolacrimal duct, also known as a tear duct. Tear ducts are responsible for draining tears away from the eye and into the nasal passage. If these ducts become blocked, tears can overflow and run down the face instead of draining properly, leading to watery eyes.
In these situations, veterinary examination is necessary. A vet can carefully check for and remove any foreign material and assess the tear ducts’ function.
Conjunctivitis (Pink Eye)
Red and inflamed eyes are a hallmark sign of conjunctivitis, commonly known as pink eye. This condition involves inflammation of the conjunctiva, the clear tissue covering the white part of the eye and the inner surface of the eyelids. Besides redness, other symptoms of conjunctivitis in cats include:
- Watery eyes: Often a primary symptom.
- Swollen eyes: The eyelids and surrounding tissues may appear puffy.
- Increased sensitivity to light: Your cat might squint or avoid bright light.
Conjunctivitis in cats can be caused by various factors, including viral or bacterial infections, allergies, or even the feline herpes virus. While some cases of conjunctivitis might seem mild, it’s essential to seek veterinary treatment. Untreated conjunctivitis can lead to more serious complications. Treatment often involves eye drops or ointments prescribed by a veterinarian, depending on the underlying cause.
Eye Infections
Discharge from your cat’s eye, especially if it’s sticky, yellow, or green, is a strong indicator of an eye infection. The color of the discharge can sometimes offer clues about the type of infection:
- Clear discharge: May suggest a viral infection.
- Yellow or green discharge: More likely indicates a bacterial infection.
Eye infections in cats require prompt veterinary attention. Early diagnosis and treatment are crucial to prevent complications and ensure your cat’s comfort. Bacterial eye infections are typically treated with ophthalmic antibiotic drops, gels, or ointments. Oral medications are usually not necessary unless the eye infection is part of a systemic illness.
Glaucoma
If your cat is exhibiting obvious signs of pain around the eye, if the eyeball appears to be bulging, or if there is noticeable swelling, glaucoma should be considered. Glaucoma is a serious and painful condition characterized by increased pressure inside the eye. Symptoms of glaucoma in cats are an emergency and require immediate veterinary care. This condition can develop rapidly, and unfortunately, significant vision loss can occur by the time symptoms become apparent.
Feline Upper Respiratory Infection (Cat Cold)
Watery eyes accompanied by other cold-like symptoms, such as sneezing and nasal discharge, often point to a feline upper respiratory infection (URI), commonly known as a cat cold. These infections are often viral and can cause a range of symptoms, including:
- Watery eyes
- Sneezing
- Runny nose
- Coughing
- Lethargy
- Loss of appetite
Many cat colds are mild and resolve within a week or so without specific veterinary treatment. However, if your cat’s symptoms worsen, don’t improve within a few days, or if they stop eating, it’s important to consult your veterinarian to rule out secondary bacterial infections or other complications.
When to See a Veterinarian
While some mild cases of watery eyes might resolve on their own, it’s crucial to know when veterinary intervention is necessary. Seek veterinary care for your cat’s watery eyes in the following situations:
- Watery eyes persist for more than a day or two.
- Your cat shows signs of pain, such as pawing at the eye or vocalizing.
- You observe symptoms of infection, like yellow or green discharge.
- The eyes are red, inflamed, or swollen.
- Your cat is squinting excessively or sensitive to light.
- Watery eyes are accompanied by other symptoms like sneezing, nasal discharge, lethargy, or loss of appetite.
A veterinarian can perform a thorough eye examination to determine the underlying cause of your cat’s watery eyes and recommend the appropriate treatment plan to alleviate discomfort and address the issue effectively.
