Caches from eastern woodrat (Neotoma floridana) dens were analyzed for plant-species composition, abundance, and energy content. Body mass and sex of den residents and the den volume were measured to determine correlations with energy content of caches. We found no difference between males and females in den volume or energy content of caches. However, a positive correlation existed between body mass of the cache owner and the amount of energy stored in the cache, such that larger individuals had a disproportionately greater reserve of energy stored in caches than did smaller individuals. The disparity suggests that small individuals are forced to forage outside the den more often than large individuals.
