Warthogs are charismatic African wild pigs whose rooting, wallowing, and territorial behaviours pose specific challenges in zoo environments. Meeting their needs improves welfare and visitor education value.
Warthog welfare in zoos is centred on providing for their intense foraging motivation. Rooting substrate is a fundamental requirement — deep, varied soil or substrate allows expression of this time-consuming, rewarding behaviour. Without rooting opportunity, warthogs show repetitive pacing, snout rubbing, and substrate-directed oral stereotypies. Mud wallows are essential for thermoregulation, especially in warm climates or heated indoor exhibits, and their absence causes thermal stress and skin irritation. Burrow structures must be provided for sleeping and refuge, with adequate size for adult animals to enter comfortably. Social management must reflect natural patterns — mixed-sex groups require careful management to avoid male aggression outside breeding seasons. Scatter feeding and buried food items extend foraging time and reduce boredom. Warthogs are often underestimated as cognitively simple, but benefit significantly from puzzle feeders and novel object enrichment.
