Rodent enrichment devices - evaluation of preference and efficacy (1997)

Coviello-Mclaughlin, G. M., Starr, S. J.

Abstract

The mice preferred cotton nestles and cardboard rolls over wooden block and commercial toys. When animals wearing wound clips were exposed to the preferred enrichment, premature wound clip removal decreased, suggesting a positive effect of enrichment on the psychological well-being of surgically manipulated mice.
