Abstract

We modified a stainless steel multiple-animal wire-bottom cage by covering one-half of the floor surface with a solid plate of stainless steel [emphasis added]. .. At night, rats demonstrated a significant (P <0.05) preference for a solid-bottom stainless steel floor. During the daytime rats significantly (P <0.05) preferred the wire-bottom side of the cage.
