The foraging strategy and dietary habits of the pygmy slow loris are not unlike those of its larger relative, the slow loris. The animal is a nocturnal feeder, preferring to search for all of its food items under cover of night. They are capable of moving faster than slow lorises. Individuals forage alone, and mothers even "park" their infants in a safe place rather than carrying them along when they venture out.
Pygmy slow lorises are opportunistic feeders, consuming a wide variety of plant and animal material. They prefer soft fruits and gums, but will readily consume tender shoots and other plant parts. Pygmy slows have been observed gouging tree branches in an attempt to stimulate a flow of edible gums/sap.
They do not eat leaves, but may often lick them for moisture. The pygmy slow loris diet also includes a fair amount of animal protein, which comprises perhaps as much as 33% of the total. They are expert in catching insects, and often capture those that have a particularly pungent odor, which the lorises can track with their keen sense of smell.
