Aspen wood-wool is preferred as a resting place, but does not affect intracage fighting in male BALB/c and C57BL/6J mice (1999)

Abstract

The nesting material [aspen wood-wool] used in this study did not cause any adverse effects on the animals, as determined by both behavioural and physiological observations. On the other hand, it might have a positive value for the animals; the material was clearly more preferred as a resting place than was conventional bedding and the animals did manipulate it during their active periods. These behavioural findings suggests that nesting material may improve the cage environment of laboratory mice.
