Hi Petrina,

I’m not sure what the needle your cat was given so it’s difficult to determine if that treatment needs to be continued.  The discharge you are also seeing has the potential of being a bacterial infection.  If left untreated, it could inflame the airways enough to where his sense of smell is affected enough that his appetite might diminish.  Also, if this discharge were to migrate to the lungs, deeper infection could set in.

While I can’t outright say what the diagnosis is, here’s my thoughts.  This sounds like a problem in the nasal areas where I would begin to suspect something called a nasopharyngeal polyp.  The snoring and wheezing can be associated with this as it causes some airflow obstruction while breathing and while this kind of an issue is rarely life-threatening, it should be addressed by your veterinarian.

Your cat will need to likely be sedated and have some radiographs done of the skull as well as a full oral exam and visualization of the eardrums.  After this is done, it can help rule out some other possible diagnoses and a more specific treatment plan can be developed to help him out.  Surgery may be needed to fix the underlying problem.

Best of luck and I hope things work out for your cat.
