What causes a cat's eyes to be watery daily, even after vet check?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

My cats eyes are always watery. Ever since I have found him his eyes have been watering. We had him neutered and checked out by a vet and they said he was fine, and it stopped for a few days but now it’s almost daily. Either one eye or both. He never seems to be in any pain or discomfort tho when you wipe his eyes clean. Im just worried as it might be something serious.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Excessive tear production in cats is from an infectious disease nearly 100% of the time the most common by far is feline herpes virus. It is species specific meaning people can not get it. However, people can act as a carrier from one cat to another. If excessive tear production is the only noticable clinical sign, at home monitoring is a viable option. Things to watch for include squinting, raising of the third eyelid, redness of the whites of the eye and or third eyelid, rubbing at the eyes, sneezing, coughing, and a cloudy appearance to the eyes. If any of those are noticed, Leo needs to be rechecked immediately. Usually viral eye infections are self-limiting but not always; topical eye treatments and oral medications can be used to help him recover more quickly if indicated. These types of medications would need to be prescribed by a veterinarian. Hope this helps!
