Aww, in that first pic of Aro you can see orange on the side of his face
And a white spot on his cheek
Do you think your boys enjoy your company more than the girls? I've heard boys love people more because they can't be housed with male mice (well, American male mice can't, I know its slightly different with Europeans) so they crave human company. Whereas girls don't crave human company as much because they have each other (although they can still be really sweet).
I've had 3 mice- 2 males, 1 female. Scabbers, one of the males, was very sweet and calm. Lucy was more hyper and a bit shy but still sweet. Eek started out fairly sweet but later started biting so I tried not to handle him very much. In the future I plan on having a big Martin R-695 cage and having like 6 rescue girls in it and then a separate cage or two for male mice.
