He still gets "episodes" of it now and then, and it will most likely be what kills him, but so far he's doing pretty good.

Also, the site lists some antibiotics to use. I didn't end up using any, just cut down the number of rats in each group, and started cleaning cages at least every other day. Good luck
I just read that link. That makes me really sad. It says stress can also lead to it. Herman (the weaned pet rat) was orphaned at about 1 week old, and has been bottle feed in addition to fostered by a two mother rats. Unfortunately due to the second mother also dying I had to wean them at around 3 weeks because I only have two lactating rats for all of the babies. (We did have 40 but I feed off some to bring their numbers down.

Plus since she is the favorite of my five year old I am sure he stresses her out some. Although she comes to the top when he comes by like she wants to be taken out and she hasn't bit him even though she now has teeth.

She is the tan hooded one. These pictures are from a couple of weeks ago. Do you think the mother had it and infected the whole litter when they were born?
