Cage enrichment for hamsters housed in suspended wire cages

Golden Syrian hamsters (n=99) were housed individually in suspended wire cages so that spilled food and excreta could be removed. After 8 days, the hamsters developed bizarre aggressive behavior which consisted of growling, hissing, aggressive posturing toward humans, destruction of...

Vibrissaeless mutant rats with a modular representation of innervated sinus hair follicules in the cerebral cortex

Specialized areas in the cerebral cortex are essential to mediate the various sensory modalities and are crucial to their recovery in disease. We recently observed that prenatal photoreceptor cues are not indispensable for the development of the elaborate modular organization...

An enriched commune housing system for laboratory rats – a preliminary view

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...

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...

Should large rats be housed in large cages? An empirical issue

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...

The effect of scents on the territorial and aggressive behaviour of laboratory rats

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...
