Importance of Enrichment

According to the Guide for the Care and Use of Laboratory Animals, “the primary aim of environmental enrichment is to enhance animal well-being by providing animals with sensory and motor stimulation through structures and resources that facilitate the expression of species-specific behaviors and promote psychological well-being through physical exercise, manipulative activities, and cognitive challenges according to species-specific characteristics.”

 

Social housing is considered by AAALAC International as the default method of housing unless otherwise justified based on social incompatibility, veterinary concerns, or scientific necessity approved by the IACUC.

 

The Guide also states that single housing of social species should be the exception and justified based on experimental requirements or veterinary-related concerns about animal well-being.
