Genius mouse

This is by far the smartest mouse I've ever bred; she made a comprimise to get her own way. She had a litter, and was still lactating but the babies were old enough to be weaned. Then I introduced another mother and her babies into the cage. The babies she was fine with, but she fucking HATED Midnight, the black mouse she's beside in the pic. I took her out for a day and night, then tried putting her back. She hadn't forgotten her intense dislike, she nipped Midnight irritably, then went straight to the babies and nursed. She hasn't attacked Midnight since. Normally mice that don't get along have to be kept seperate for life. But this little mouse I call Tri has made a very unusual exception to the rule. It is clear that she desperately wanted more babies and badly wanted the ones I introduced, even though her enemy was their mum lol. They seem to get along fine now. I've yet to have any problems. I had no idea mice could be THIS smart.
