Large carnivores including lions, tigers, wolves, and bears present some of the most challenging welfare scenarios in zoo settings, requiring extensive space and complex environmental provision.
Large carnivore welfare in conventional zoo exhibits is frequently compromised by the fundamental mismatch between the species' natural ranging behaviour and exhibit size. Lions that patrol territories of 100-400 square km cannot meaningfully range in even the largest zoo enclosure. The welfare response — stereotypic pacing, increased resting, reduced activity diversity — is documented at high rates across zoo carnivore populations. Progressive zoos have invested in much larger naturalistic exhibits and enrichment programmes that reduce but cannot eliminate these welfare deficits. The debate about whether large carnivore welfare can be adequately met in zoo settings continues.
