Food deprivation-induced increases in hoarding by Siberian hamsters are not photoperiod-dependent

Siberian hamsters increase food hoarding in response to chronic food restriction and food deprivation, conditions that lead to a loss of body mass and fat. Therefore, the first purpose of the present experiments was to test further the effects of...

Reduction of fever by housing in small cages

At the beginning of the experiments individual hamsters housed in small standard cages had higher temperatures compared with hamsters housed in larger cages. This was taken as an indication of a higher stress level in the small caging environment. Hamsters...

Revolutionary science: an improved running wheel for hamsters

Standard rod wheels (diamter 17.5 cm) are preferred to small wheels (diameter 13.0 cm). Placing a plastic mesh around the floor of the running wheel greatly increases the number of revolutions made.

Housing-induced changes in the febrile response of juvenile and adult golden hamsters

Small caged diminish the expression of fever and increase baseline rectal temperature, likely due to a higher stress level.

Enrichment in group-housed laboratory golden hamsters

Enriched hamsters [four same-sexed animals per group] showed varied behavior and less aggression toward their cagemates. The hamsters preferred jars to pipes probably because the jars' greater height, as compared to pipes, made it easy to look outside the cage.

Diet self-selection and food hoarding after food deprivation by Siberian hamsters

Siberian hamsters (Phodopus sungorus) increase food hoarding, but not food intake, after a fast. Because the physiological mechanisms underlying these changes in food hoarding are virtually unknown, we sought insight into these mechanisms by allowing hamsters to self-select their diet...

In summary, solid-bottomed cages with bedding material are preferable; in general, group housing is preferable to individual caging so long as the groups are formed early in life, are stable and harmonious. There should be room for hiding and escaping...

Revolutionary Science: An improved running wheel for hamsters and mice

Golden hamsters and mice ran more in wheels with the floor covered with plastic mesh than in wheels with the usual metal rods. Small diameter wheels were preferred less than standard 17.5-cm wheels.
