Tigers are solitary apex predators whose welfare in zoos depends on large territories, sensory enrichment, and management that respects their solitary nature.
Tiger welfare in modern zoos has improved dramatically from mid-20th century cage standards but fundamental constraints remain. Their solitary nature means housing tigers together — except for managed introductions — causes chronic stress, competition, and injury risk. Enclosure sizes, while vastly improved, cannot replicate the kilometers tigers traverse daily. Behavioral enrichment that engages their predatory instincts — olfactory trails, novel prey items, complex feeding challenges — is essential to prevent behavioral stagnation. Tigers in well-managed facilities show varied natural behaviors including swimming, scent marking, and exploratory activity. Tiger farms in Asia — some holding thousands of animals in small cages for the commercial trade in tiger bones and products — represent the extreme opposite of welfare-positive tiger keeping and are widely condemned.
