I could be wrong, but I think they have to actually swab his vent. But they will let you know what you need to do. Please keep us updated on the litle guy! If you do find out that he has adenovirus, I can give you supplement information. Also, you can PM Drache613 because she is a PRO with adeno. She's the one who helped me get my girl healthy, and she's actually currently working to find a cure for it.
