Sorry it has taken me so long to reply. I have not made any of the changes in household or cleaning products that you listed. We have had a cold winter this year, and she and I have been closed up inside with the heat on. Sometimes the dry air inside has affected my own sinuses. Maybe she is...
My cat has started to sneeze a lot. She doesn't seem to have any other symptoms. She eats well and acts like normal except for this occasional sneezing. Has anybody else had this experience with their cat?
