Environmental enrichment for laboratory mice (Mus musculus) (1991)

Ward, G. E., DeMille, D.

Abstract

It must be considered as doubtful whether the current bland and unenriched laboratory animal cage environment is either sufficient or able to fulfill the legitimate requirements of this species. Water bottles containing sawdust provide effective cage enrichment for laboratory mice. They are used selectively as latrines or remain clean to be used as nests.
