The feeding behavior of the deer mouse, Peromyscus maniculatus, includes food hoarding as well as ingestion. In this animal the mu opiate agonist, morphine, and the kappa opiate agonist, U-50, 488H, selectively stimulate food hoarding and ingestion, respectively. This suggests that mu and kappa opiate systems may differentially mediate primary components of natural feeding behavior.
