...at the same time? can i get 2 pet mice at one time (or more) if i did would they get along if i got them from the same place at the same time?

also with pet mice do they let you hold them? or do they run? just some info on them or some internet links please? are they fun pets? also what kind of cage is best? can they escape easily like hamsters? would an aqarium be best? mabye a link or pic link of a good cage?! thnx
