Slow lorises eat insects, small birds and reptiles, eggs, fruits, gums, nectar and some vegetation. A 1984 study of the Sunda slow loris found its diet was 71% fruit and gums, and 29% insects and other animal prey. A more detailed study of another Sunda slow loris population in 2002 and 2003 showed different dietary proportions: 43.3% gum, 31.7% nectar, 22.5% fruit, and just 2.5% arthropods and other animal prey.
