It has thick, woolly fur of varying colours depending on age, sex, and location. Males are typically grey/white or brown/white with splotchy patterns on their back and a white underbelly. Only males have spots. Females are usually white or grey and unspotted. Some completely white individuals are known in both males and females. As the young grow, they go through a series of color changes before reaching sexual maturity around one year old. Colouration varies from reds and whites to buffs, browns, light greys, and blacks. Unlike some other species of cuscuses or possums, the common spotted cuscus does not have a dorsal stripe on its fur.
