Cat eye infection not clearing with Terramycin. When to see vet?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 10 lbs

My kitty gets eye infections in one (her left)eye every couple months. Eye waters, she squints and it is pink. It has been six days using Terramycin oint ment and the redness is gone and she squints it half the time and its still watery. She has sneezed once. She is vaccinated. Should I continue Terramycin for another week or visit the vet?

Poor Snowball! Since she is still squinting with watery eye discharge after 6 days on Terramycin, you should take her to the vet now. The most common cause of recurrent eye issues and sneezing is due to viral infections (herpesvirus and calicivirus) that can cause both eye and upper respiratory signs when they shed intermittently. Signs typically resolve once the virus is done shedding, but many cats can also develop secondary bacterial infections which require antibiotics for treatment. In the long term, discuss using a Lysine supplement (Viralys is one example) for Snowball with her vet. I hope that all goes well for Snowball!
