I'm under the impression that both of my new rats might be suffering from a respiratory infection I had them out today on the bed with me and one of them started wheezing heavily which coincided with his breathing. They've been sneezing a lot but I assumed that was being in the new environment at my house. I don't know if the wheezing was stress related, and I haven't noticed any red on their eyes or nose. But I'm taking them to the vet tomorrow to be sure. I will take care of my ratties even if I've only had them for 3 days! Love these guys so much.
