Environmental Enrichment

An enriched environment for the African clawed frog (Xenopus laevis)

A continuous-flow aquatic housing system for frogs is described. Sandstones and a stainless-steel rabbit feeder were used for enrichment. The animals swam into the feeders immediately, and three of four animals usually occupy each feeder at any given time.

A semi-natural habitat for housing small, nonhuman primates

A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and more economical to maintain than...
