Do two Siberian mice or 1 Siberian mouse and one rat get along better?

Two Siberian mice are likely to get along better than one Siberian mouse and one rat. Mice are social animals and often thrive in groups, while rats may see mice as competitors or prey. Additionally, the social behaviors and needs of the two species differ, which can lead to stress or aggression in mixed-species situations. Therefore, keeping two Siberian mice together is generally a more harmonious choice.
