Why is my cat still sneezing after a vet visit for a viral infection?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 3 years and 9 months old | 14.9 lbs

we took my cat to the vet about a week ago. he had a viral infection i think (sneezing, coughing). the vet gave him a shot for that and a shot for his bad breath (corizone? i think that’s what it’s called) and everything went good and his symptoms went away but a few days ago he started sneezing SO much. Like sneezing his head off. And he’s still sneezing. A lot. But his snot isn’t green like it was. Do I need to do something or let it be? btw he’s acting/eating normal.

Hello. It is good that Echo is still eating & acting well. Most of these upper respiratory infections usually just need a week or so to run their course. I am not sure why your vet gave him a steroid injection for bad breath ( this was your cortisone ) unless he actually had lesions in his mouth. This might have exasperated his previous infection to continue into this. I would not recommend giving anymore cortisone while Echo is trying to recover from this infection. The sneezing in bothersome, but not really worrisome as long as he feels fine. See how he is come Monday, & at this point it might be appropriate to treat with either another round of antibiotics or an antiviral medication.
