My cat's eye is swollen and has pus. Is it serious or will it heal?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 10 lbs

So i noticed today that my male cats left eye is swollen and filled with puss. Im thinking he must have gotten in a fight with another cat and he got scratched in the eye. I think hes blind now in that eye but i cant see anything other than just puss. Im wondering if this is serious and needs to be treated right away or if it will be okay and heal on its own? Thanks.

Poor Tiger! It sounds like he may have a corneal ulcer or very severe conjunctivitis. Eye conditions can be very painful and can quickly progress to emergencies, so Tiger should be seen by a vet right away, as an ulcer is unlikely to heal on its own. In the meantime, you can get Tiger an E-collar or "cone" to prevent him from scratching the eye and causing further trauma. I hope this helps and that all is well with Tiger!

    Hello, and thanks for your question on Petco Pet Education Center, formerly Petcoach. The most important thing you can do for Tiger is to have him seen by a vet. It is important to know why Tiger's eyes are painful, to make sure he is treated with the correct medication. He could have an infection, or a scratch/corneal ulcer, among other possibilities. Your vet will be able to identify the problem and make sure he is treated correctly. I do not recommend administering anything over the counter, as it is possible to do harm rather than good. Hope this helps!
