I have a small colony of rats 1.3 or so I thought. One that I thought was female has not become pregnant at all, so pulled her out again and was checking her out. Nipples are present, and it kind of looked like when a young male sucks them up so I pressed on the belly a little and I thought I was going crazy. I asked my wife to look and "It's a hermaphrodite" came out. Has anybody else heard of this or seen it?
