Biology and behaviour
The target rat is largely nocturnal and feeds on the ground on green vegetable material and fallen fruit, supplementing these with some insects. In addition to moving along the ground, it often climbs into the rainforest understory, although not high into trees. It has been reported to construct spherical nests of shredded grass.[ Little is known of the social organisation of this species but in Cameroon a group of thirteen was caught at one location in an ]oil palm
