Alright so my one rat had an oops litter. From the beginning. Last weekend she had 2 babies whom died. But she still looked extremely pregnant. I took her in, fearing she was having complications. They did not see anything baby-wise but did notice something. They gave her oxy injection to push anything out. Well, She has still been huge, so i thought maybe tumor as Ive been able to easily feel her ribs and spine. This morning 4/20 I wake up and there are now 12 babies in with her. She is now thinner than a rail and looks sickly. I am worried about her and the babies. I checked them, I cannot see any milk band as of yet. Is it still fairly early to tell? Should I contact a vet? I gave her eggs and some fruit. Should I separate her and the babies from my other 3 females? Her sister seems to be trying to help care for the babies as she is constantly with them along with momma. I would hate to disturb anything but I dont wanna lose more babies. They are noisy and seem to be doing better than the first 2 that had been born. Any help and advice is appreciated.
