Ok, thanks for the info.

She doesn't open mouth breath all the time, just once and a while. Other wise she just seems to have labored breathing. I have some Baytril left over from the other ratties, it doesn't expire til 2006. I think I am going to give the left over Baytril to her myself, before spending $100 on a vet visit to give me the same stuff that I have now anyways. If she gets worse/appears to be in pain, then I will take her in.
