Yeah there both rex'sOnlyOno said:i don't think that she looks very pregnant but you might want to keep a close eye on her. my nakie rat looks all fat and round when she cleans her belly like that too. and their nipples are kind of always showing, lol. if she's really preggers they will actually protrude from her belly, which is the only reason that you can even see that on a normal hairy rat.
that little dark baby is so cute! but i think your pinky rat is still technically a double-rex since her face is hairy too, no?
