Demonstration of Preference for Clean Versus Soiled Cages As Expressed by Laboratory Mice

Mice in cages with flooring consisting partly of wire mesh and partly of sawdust bedding chose the bedded area for sleeping. They kept their sleeping area clean and deposited almost all their excreta on the wire mesh. When offered a...

The role of substrate odours in maintaining social tolerance between male house mice (Mus musculus domesticus)

The group's odor cues protects the individual group member from being attacked. Strangers who do not have this group specific odor cue are attacked.It may be good advice to always leave some soiled bedding to assure group harmony in the...

Sound levels in rooms housing laboratory animals: An uncontrolled daily variable

It is clear that the acoustic environment of laboratory animals is a daily variable that is usually uncontrolled and that may have important implications for behavioural and physiological experiments and for animal welfare.

The cage design affects intermale aggression in small groups of male laboratory mice: strain specific consequences on social organization, and endocrine activations in two inbred strains (DBA/2J and CBA/J)

The provision of a horizontal labyrinth consisting of vertical dividers with only a few openings enhanced territorial tendencies in groups of male mice, leading to increased aggression. Findings revealed strainspecific environmental effects on both social organization and endocrine states.

Effects of environmental enrichment on aggressive behavior, dominance hierarchies, and endocrine status in male DBA/2J mice
