Bayne, K. 2010. Enrichment and behavioral management programs around the world. Enrichment Record 4, 4-7.

To do justice to the diverse approaches to enrichment and behavioral management around the world would entail a discussion beyond the limits of this publication. Therefore, guidelines and regulations in a representative sample of countries in select regions of the world [U.S., Europe, China, Singapore, India] will be described to give a sense of the status of this program element world-wide. Although a direct comparison between European and U.S. cage space for rodents cannot be precise due to the different weight categories used in the Directive and the Guide, it is clear that in general more cage space is afforded mice and rats in Europe.
