My cats usually don't sneeze before, maybe once in a while. But recently I found them sneezing more frequently, like 4-5 times a day for Metoo and a little less for Meatball. It looks like they usually sneeze when they are on my laps. I don't know why? They don't seem to get a cold, as their activity level, appetite, etc. are all normal. My home is very warm too. And I certainly hope they are not developing an allergy to human! Could it be because the room is quite dry? (There are quite a lot static electric building up coming into winter.) Anyone knows what I can do to help? Thanks!
