Why is my cat squinting one eye and has eye discharge? Vet or wait?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 1 year and 2 months old | 11.2 lbs

Cat squinting with one eye and has some eye discharge. Discharge is clear/brown/grey. Should I wait it out or see a vet immediately? Does it mean something serious or is it likely he can fight it off on his own? Just noticed this morning, worried he picked up a virus but money is tight right now so I don’t want to rush to the vet if it’s not serious!

A squinting eye is never good - usually means pain like there is a scratch or something on the cornea. He should see a vet as soon as possible. If it is a scratch and not treated quickly can get worse and cause you more trouble/money in the end.

    Hi, and thanks for your question. That is likely to be due to a mild to moderate conjunctivitis, probably secondary to a trauma or infection. A check up would be needed as appropriate treatment would include antibiotics and anti-inflammatory eye drops. Corneal injuries must be ruled out as well. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

    The squinting and eye discharge in only one eye usually means there is something other than allergies as the cause. It could be something that rubbed on her eye, like sand, something stuck under the eyelid, corneal ulcer or abrasion, among a few other things. I would recommend taking Lucy to the vet for evaluation.

    Thank you for submitting your question regarding Nala. I am glad that she will see her veterinarian again. She will likely need eye tests to try to get a more accurate diagnosis on her eyes. She could have a corneal ulcer (scratch across the surface of her eye), an upper respiratory tract infection that involves the eyes or even inflammation within the eye of itself. Rarely a patient can experience a drug reaction. So this is possible if the eyes got worse after applying the ointment. In the meantime, keep the eyes clear of any discharge. Wipe it away gently with a warm washcloth. If she is pawing at the eyes, place an E-collar on her to prevent her from causing further damage. I hope this information helps!

    Hi, I would strongly recommend to have her eye checked by a vet first, as can be damage to the cornea which happens quite common in fighting injuries so the vet will need to stain the eye and asses the cornea. If the cornea is scratched it will need immediate treatment with close monitoring and follow up. The course of treatment will depend upon the severity of the injury and the part of the eye that was injured. Some eye drops can cause even more damage to an eye with ulcerated cornea so a vet need to decide the drops to be used on the eye.
