Thats what I thought a couple days ago when the sneezes started. he's gone from just sneezes to congested sneezes, possible coughs, and a runny nose. poor fellow. It's easier to take him in and get checked out to be safe. Every sneeze now is like a human congested sneeze (I don't know how to describe the noise lol).
Feel free to message me any questions, I'll try to help the best I can!
