Theo's sneezing fits have continued and I really wish there was something I could do to help him out. I may call the vet this morning.
One of the things I tried was bringing him into the bathroom with me this morning while I took my shower. I thought the steam might help clear his sinus out. Usually when I'm taking my shower he's right outside the door mewing away. Today being on the other side of the door, he wanted nothing more than to be out of the room. He didn't sneeze the entire time however so it might have done some good even if the stress probably did not.
