Chimpanzee beds and human beds can both accumulate dirt, debris, and microorganisms. While chimpanzee beds may have various natural materials like leaves and twigs, they may not necessarily be dirtier than human beds, which can accumulate dust, dead skin cells, and other materials. Hygiene and maintenance practices greatly impact the cleanliness of any bed, regardless of whether it belongs to a chimpanzee or a human. For humans, regular cleaning and changing of bed linens are essential for hygiene. Similarly, chimpanzees can maintain relatively clean beds by regularly shifting and replacing nesting materials.
