Effect of predatory stress on sucrose intake and behavior on the plus-maze in male mice

The authors accomodated mice in the same room as rats, and noticed that these mice left a higher number of fecal boli in the elevated plus-maze test and that they showed a higher level of anxiety than control rats. It...

Behavioral indexes of poor welfare in laboratory rats

Fearfulness associated with single-housing was alleviated by pair-housing, and even further alleviated by group-housing in enriched cages. Problem solving ability was improved when rats were kept in groups in enriched cages rather than in barren single cages.

Enriched environment increases neurogenesis in the adult rat dentate gyrusand improves spatial memory

The results suggest that environmental cues can enhance neurogenesis in the adult hippocampal region, which is associated with improved spatial memory.

Why do male ICR(CD-1) mice perform bar related (stereotypic) behaviour? Behavioural Processes 47, 95-111

Bar behaviour is likely to stem from a motivation to leave the cage.

Strain-specific effects of cage enrichment in male laboratory mice (Mus musculus)

The relationship between aggression, testosterone and 'enrichment' [clear Perspex tunnel and a small handful of shredded tissue] suggest that increasing complexity in laboratory cages may increase a naturally selected territorial response in some strains. ... Enrichment, as used in this...

Isolator rodent caging systems: a critical review

The past 15 years have brought remarkable changes to the way we house rodents used in research. These changes coincided and, to a great extent, were driven by a marked increase in the use of genetically engineered mice. Notable changes...

Practical rodent enrichment

We have designed and evaluated two forms of rodent enrichment: (1) Floor feeding, where in addition to the standard diet present in the cage hopper, other food is mixed into the cage substrate; (2) A cage insert, which incorporates a...
