Tigers are solitary animals whose welfare in captivity depends on understanding and respecting their natural asocial biology while providing the environmental complexity their large territories normally provide.
Tiger welfare in zoos requires respecting their fundamentally solitary nature while providing the environmental richness their large natural territories normally offer. Forcing social housing beyond carefully managed breeding pairs causes chronic stress in animals that evolved for solitary territorial lives. Environmental complexity — large spaces with varied terrain, pools for thermoregulation, climbing structures, and olfactory enrichment that engages marking behavior — is the primary tool for achieving welfare in solitary confinement. Modern tiger exhibits that provide these features achieve significantly better welfare indicators than barren or undersized traditional enclosures that remain in use in many facilities globally.
