I have had Emily for almost a year now and in the past few months she has started to sneeze. I am not sure if this is related to seasonal allergies (human allergies are really common in this area) or maybe the pollution (which gets really bad when it gets hot). It doesn't occur every day, but it is almost like she has a little tickle in her nose. I have read that cats aren't supposed to sneeze and if they do it can be a problem. I have taken her to the vet a few times and had thorough checkups done but nothing has ever come up.

Any suggestions...
