Whitehead’s spiny rat is believed to be monogamous, with each breeding pair occupying a home range that is defended against other spiny rats (8). It is believed to breed throughout the year, at least in peninsular Malaysia, and has one to six young per litter (5).
A nocturnal animal (8), Whitehead’s spiny rat spends its nights foraging on the forest floor for a wide range of plant material, such as fallen fruits and seeds, with a preference for oil palm fruit (10). However, as an omnivorous species, its diet also includes arthropods (8). Like other spiny rats, it is a hoarder, storing seeds in deep underground burrows that are dug by other forest animals (11).
Whitehead’s spiny rat is eaten by a number of predators, including the leopard cat (Prionailurus bengalensis) (9).
