So far Sunny seems to be acting normally but still sneezing occasionally. I'm not too concerned because it's happened before. His eyes and nose also look normal so I really don't want to medicate him unless he becomes worse. Storm and Cirrus are fine too which is a relief. At first I thought it could be the beginning of a URI but if it was I think that Storm and Cirrus would have picked it up by now. I'll let you know if anything changes. Thanks for your concerns.
