Ndume enjoys resting on one of his new ergonomically designed rubber mats, generously donated to both gorillas, Koko and Ndume, by Working Concepts, inc.. As the gorillas spend a fair amount of time indoors during the winter (now approaching) they really appreciate having something this comfortable to sit, stand, kneel, lie or play on – as do their caregivers.
