I already mentioned this but I had a whole litter of eating, strong, healthy appearing bluestripe ribbons die of a blister disease. One day, great! The next one by one drop dead covered in blisters. Conditions where the same as 2 litters of peninsula ribbons born that same week. They are are fine! Males and females where housed separately and they both came down with it at the exact same time. Really NO explanation. Oh. And they where being kept dry too so it wasn't like a scale rot thing.

It sucks... So sorry about yours I know how it feels.
