Animals’ natural behavior andactivity profile should be considered during evaluation of suitable housingor behavioral assessment.Animals maintained in a laboratory environment are generally restrictedin their activities compared to free-ranging animals. Forced activity forreasons other than attempts to meet therapeutic or approved protocolobjectives should be avoided. High levels of repetitive, unvarying behavior(stereotypies, compulsive behaviors) may reflect disruptions of normalbehavioral control mechanisms due to housing conditions or managementpractices (Garner 2005; NRC 1998a).Dogs, cats, rabbits, and many other animals benefit from positive humaninteraction (Augustsson et al. 2002; Bayne et al. 1993; McCune 1997; Poole1998; Rennie and Buchanan-Smith 2006; Rollin 1990).
