A simple, inexpensive method to minimize floor-drain obstructions while supporting environmental enrichment in primate facilities (2003)

Abstract

An important component of nonhuman primate environmental enrichment programs is affording the animals the opportunity to objects. Although these objects and various bulky food items enrich the quality of life for nonhuman primates, they complicate the duties of facility maintenance personnel. A prime example of these sometimes costly complications is a seemingly never-ending series of floor drain obstructions. We devised a simple, inexpensive modified drain cover that prevents large items from entering the drain. The total cost of materials for this device was $1.12, and it required only 15 min of labor for assembly.
