Warthogs are highly social African wild pigs with strong instincts for rooting, burrowing, and mud bathing. Zoo welfare programs must accommodate these needs to prevent boredom and stereotypic behavior.
Warthogs in zoo settings require deep substrate for rooting behavior, mud wallows for thermoregulation, and appropriate social groupings. Solitary housing of social animals causes measurable welfare harm. Enclosed environments without rooting substrate lead to redirected rooting on hard surfaces, causing wrist injuries. Artificial burrows or hide boxes allow thermoregulation and provide security. Warthogs are often underestimated in their cognitive complexity — enrichment programs that engage problem-solving motivation are more effective than passive objects.
