Prairie deer mice prefer contraspecific flesh over conspecific flesh.
Hungry adult male deer mice were presented with freshly asphyxiated conspecifics and house mice. The deer mice showed a reliable preference for the contraspecific flesh during the first hour of testing, but this preference was attenuated during subsequent hours as subjects switched from eating the preferred parts of the contraspecific to the preferred parts of the conspecific.
