Fennec foxes are the world's smallest wild canids, adapted to Saharan desert conditions. Their welfare in zoos requires understanding their nocturnal nature, social behaviour, and extreme thermal adaptations.
Fennec fox welfare in zoos requires accommodation of their nocturnal, desert-adapted biology. Keeping fennecs active during daytime for visitor observation disrupts their natural sleep-activity cycle and causes chronic sleep deprivation stress. Thermal management is critical — fennecs are adapted to extreme heat but can also tolerate cold better than expected; however, damp conditions cause welfare problems. Their social nature means they should be housed in compatible social groups rather than individually. Deep, diggable substrate satisfies their natural den-digging behaviour and provides refuge. As nocturnal animals, low-light nocturnal house exhibits that allow viewing during their active period while respecting their diel cycle are the most welfare-positive presentation option.
