My kitten has eye discharge and red eyes after new cat. Is it serious?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 7 months and 22 days old | 11 lbs

My 7 mo. old male kitten (Samson) recently started having discharge out of both eyes, lower white part of eyes is a little red. This started just after I introduced a 12 wk old male kitten (Moses) in the home as a playmate. The 12 wk old kitten sneezes a lot but seems fine and was vetted before I got him. Both are neutered and vetted. Not sure why my 7 mo. old has discharge in his eyes. He doesn't seem in pain, still runs, plays. This is my first time having cats ever so unsure what to do.

Cats often are infected with herpesvirus as kittens, and it can come and go throughout their lives, but often it flares up during times of stress (such as adding a new kitten). They can also get secondary bacterial infections in the eyes and upper respiratory infections. If it's not improving on its own or he starts squinting or pawing at his eye he may need antibiotic drops from your vet.
