So I took my new baby rats to the vet this morning (they have funny little bumps on their ears) and my vet resexed them. THEY ARE TWO NOT BROTHERS!!! Its a brother and sister!!!Also, they are around 7 weeks old...I think my girl could be pregnant now because she was kept with her brother, father and mother.What now?P.S. I've already separated them. Also, I've renamed them Mikey (boy) and Micha (girl).
