Give a rat a bone: satisfying rodents' need to gnaw

Abstract

Gnawing is an important natural behavior for rodents. Rodents' teeth grow continuously throughout their lives, and gnawing maintains their dental health. In keeping with recommendations of the Guide for the Care and Use of Laboratory Animals, rodents should be provided with enrichment items that encourage gnawing as a natural behavior. Bio-Serv offers two different types of chewable bone-shaped enrichment items for lab rats and mice that are safe and economical.
