Abstract

Five options were tested in alternation: crushed monkey chow in wood shavings, plastic ball, empty plastic bottle, PVC tube with finger holes and loaded with litter-nut-dried fruit mix, plastic jug with litter-nut-dried fruit mix. The two food dispensing objects were the most successful items in the single-housing setting.
