Last sunday I brought home 20 CH female balls from a local expo. All are doing good but one, I checked them all over today and discovered one was showing signs of a respiratory infection. Her mouth is somewhat swollen and puffed out slightly, and I saw a tiny bit of mucus around her mouth. I have her isolated from the rest of the CH females as well as the rest of my collection. I do NOT hear any puffing or weezing. Aside from calling the vet (will do tomorrow) what else should I be doing?
