Lions, tigers, and leopards in captivity require extensive enrichment to prevent stereotypic pacing and express natural hunting and territorial behaviors.
Big cats are among the most compelling examples of the gap between natural behavioral ecology and captive conditions. Their evolved need for large territories, solo hunting, and complex sensory landscapes cannot be replicated in any zoo enclosure. However, targeted enrichment programs can provide meaningful engagement with species-appropriate stimuli. Olfactory enrichment using prey scents, motor enrichment through puzzle feeders that engage hunting sequences, and spatial enrichment through complex enclosure design all contribute to measurable welfare improvement. The welfare standard for big cats continues to rise in accredited facilities, with increasingly naturalistic approaches replacing barren concrete spaces.
