Abstract

Our study supports previous findings that interaction with enrichment devices decreases over time, thus indicating the need for frequent rotation of different enrichment devices. In addition, no adverse effects of the analyzed parameters were found, indicating that stainless-steel rabbit rattles on spring clips are suitable devices for safety assessment studies, in which the introduction of new variables is often unacceptable.
