Understanding the behavioural ecology of Nycticebus menagensis is vital in conducting best-practice releases for those that are rescued from the illegal pet trade. In releasing protected species such as slow lorises, whose wild populations are severely affected by the wildlife trade, it is necessary to ensure wild survival and facilitate sustainable wild populations. Two important factors determining adaptation to wild conditions and natural habitat are consuming a natural diet and appropriate feeding behaviours (Cheyne, 2006; Grundmann and Didier, 2000). If they are to survive in the wild, it is important that the diets and feeding schedules of slow lorises undergoing rehabilitation meet the nutritional needs of the individuals while mirroring natural feeding behaviours.
