Siberian (Amur) tigers are the largest felid subspecies and require extensive enclosures with cold climate management and complex enrichment for good welfare in captivity.
Siberian tiger welfare requires the largest enclosure dimensions possible, with varied terrain and complexity. Their cold climate adaptation means they benefit from seasonal temperature variation and access to outdoor areas in cold weather when many other species would be restricted. Olfactory enrichment through prey scents, novel objects and varied terrain maintains exploratory behaviour and reduces the chronic stress of environmental monotony.
