It is not uncommon for cat owners to notice one or both of their cat’s eyes watering. While occasional tear production is normal, excessive tearing (epiphora) can indicate an underlying issue. Some causes are minor, such as dust or mild allergies, while others, including infections, corneal ulcers, or blocked tear ducts, require veterinary attention.
According to PetMD, approximately 20 to 30 percent of feline veterinary visits involve eye-related concerns. Recognizing the potential causes can help determine whether home care is sufficient or if medical intervention is necessary.
Epiphora is excessive tearing caused by an overproduction of tears or improper drainage. It can result from blocked tear ducts, eye infections, irritants, eyelid abnormalities, or dry eye syndrome. Symptoms include persistent watery eyes, blurred vision, redness, and skin irritation. Treatment depends on the cause and may include eye drops, warm compresses, tear duct procedures, or surgery for structural issues. If excessive tearing persists, consulting an eye specialist is recommended.
Not necessarily. Occasional tear production is normal, especially if your cat has just woken up or been exposed to a temporary irritant like dust. However, persistent watering, squinting, redness, or discharge should never be ignored.
In the following sections, we will explore the most common causes of watery eyes in cats, how to recognize serious symptoms, effective treatments, and Finally when to see a vet.
Feature | Normal Tear Production | Abnormal Tear Production (Epiphora) |
Tear Amount | Small, occasional tears | Persistent, excessive tear overflow |
Color of Discharge | Clear | Yellow, green, or blood-tinged |
Eye Appearance | Bright and clear | Red, swollen, or cloudy |
Behavior | Normal blinking | Squinting, pawing at the eye |
Watery eyes in cats can result from various underlying issues, ranging from mild irritations to serious health conditions. While occasional tearing is normal, persistent eye-watering accompanied by redness, discharge, or discomfort may indicate allergies, infections, or structural problems. Identifying the cause is essential for proper treatment and ensuring your cat's eye health. Below are some of the most common reasons why cats experience excessive tearing and how to manage them.
Just like humans, cats can develop allergies that cause excessive tearing and eye irritation. Allergies occur when a cat’s immune system overreacts to harmless substances, leading to inflammation and discomfort. Identifying the specific allergen can help manage symptoms and improve your cat’s quality of life. Below are common allergens, symptoms, and treatment options for allergic reactions in cats.
Can Cats Have Allergies That Cause Watery Eyes?

Symptoms of an Eye Infection in Cats
How Are Cat Eye Infections Treated?
Veterinary treatment depends on the cause:
Cats are naturally curious and may encounter small debris like dust, sand, or plant material that gets into their eyes. When this happens, their eyes produce excess tears to flush out the irritant. While minor cases resolve on their own, persistent discomfort or excessive tearing may indicate a more serious issue, such as a corneal scratch. Recognizing the symptoms and knowing how to safely assist your cat can help prevent complications.
Can Cats Get Debris Stuck in Their Eyes?
