Choice by rats for enriched versus standard home cages: Plastic pipes, wood platforms, wood chips, and paper towels as enrichment items
Most [of the individually tested male] rats preferred cages with wood platforms, wood chips, and paper towels to otherwise identical [barren, wire mesh] cages. .... Plastic pipes ... were not preferred by most animals. Both wood platforms and paper towels...

It is suggested that the housing of laboratory rodents should be improved by the use of larger and moreappropriate cage types, as well as by reducing the monotonyof conventional housing systems... Guinea pigs readily chew softwood sticks.

I believe that rats housed in research laboratories in polypropylen boxes with a floor area of 1600 sqcm and a height of 20 cm are ethologically, physiologically and psychologically aberrant and cannot be considered as normal animals. An enriched group-housing...

In the present experiment, eight large rats (489-623 g) were each allowed to choose for 24 hr between a 16.8-cm-high [barren] cage and a 23-cm-high [barren] cage. The rats failed to exhibit any preference for the higher cage. It is...

In the present work we analyse social relations presented by laboratory rats (Rattus norvegicus, Wistar breed) in seminatural conditions, with special reference to behaviours of dominance, territorialism and aggressiveness, and the importance that these marks of odour play on these...

Same-sex pairs were established and partners separated after 6 weeks. The effects of 6 weeks of [subsequent] social isolation on electroencephalographic (EEG) recordings and hypothalamic-pituitary-adrenal (HPA) functioning were studied. Separation resulted in significant sleep disturbances - as measured in EEG...
