I have built up a collection of 9 rats and feeders, i've just had 2 females give birth and a 3rd about to give birth. I got all my rats from either a healthy place or a good breeder and none had any sneezes or symptons of anything. I know rats have Mycoplasma in their blood when their born and its not really a problem till something triggers it. I know the rats were stressed out when i brought them here, but just in the last week i noticed my male siamese start to wheeze and sneeze. I immediately used some ferret respiratory medication on his nose when i first saw it. Now I hear sneezes everywhere and i'm really starting to worry. The medication i have for the respiratory infections says i can put it in a humidifier to help heal through breathing it normally. I just now set it up in my humidifier and will hopefully see an improvement.
I will say that the male that was wheezing VERY bad is now just slightly sneezing, so i hope that i can help heal these problems before all my rats sneeze and get bacterial respiratory infections. Any help would be greatly appreciated as i do not want to take every rat to the vet to get charged $800 for a minor non-life threatening problem.
