Since I have no other female rats to replace the bad one, I will give her one more chance for now.

About a week before the massacre I moved my rats into lab style cages. They are nice size, and only the one pair was living in it. They are in no view of other rats. So, who knows.

The dumbo male/baby were in perfect condition. The baby was about 2.5" nose to butt.. itty bitty.
