General considerations for appropriate cage space arrangement for small monkeys.
This paper describes the introduction of a modified caging system and the benefits to both the animals and staff. The removal of metal grids at the bottom of the cage, and the introduction of direct...
Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate...
Wooden and plastic perches have been tested successfully by several hundred rhesus monkeys and 40 stump-tailed monkeys of both sexes and various ages over the last 3 years. Perches have proven an inexpensive, simple, yet...
A large, three-part playground for captive chimpanzees was constructed and evaluated in terms of area use and behavior changes. Comparative behavioral samples were obtained on 38 subjects in the existing indoor-outdoor run and in the...
We examined the effects of a synthetic fleece pad on cage stereotypies in individually housed cynomolgus monkeys. Animals exhibited idiosyncratic repertoires of stereotyped behaviour, including repetitive pacing, swaying circling, bouncing, cage charging, and rocking that...
Modification of squeeze cages is described allowing the installation of a perch that does not interfere with the normal operation of the cage.
An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a...
Several structural enrichment enhancers are described. When a barrel with an opening in the front was hung from the roof of the siamang enclosure, our then solitary male, Mitch, spent much of his time looking...
In this study artificial turf was used as the substrate for a particulate food given to the subjects as an environmental enrichment technique. When their cages were not enriched, eight single-caged subjects exhibited abnormal behaviors...
