Why is my rat still sneezing after antibiotics and eye discharge gone?

Updated on September 23rd, 2025

I purchased a small rat on 11.25.17, and he's been sneezing a lot. I took him to the vet when I saw a red discharge in his eyes. He got some antibiotics (still in treatment). The discharge is gone, but he continues sneezing. It eats and it's active, what could the problem be?

Thank you for using Petco Pet Education Center, formerly Petcoach! It is a good sign that Oliver’s red discharge has stopped. This is a substance known as porphyrin, which rats make normally in a small gland behind their eye. It is normally groomed off, but you may notice it if your rat is grooming less than usual because he doesn’t feel well. The fact that the discharge is now gone, is likely because Oliver has started grooming. Unfortunately, rats can have many bacterial infections that can cause them to sneeze and may take some time to treat. I recommend continuing the antibiotics for as long as directed by your vet, even if the symptoms decrease.
