There's a group of Buddhist monks near Kanachanaburi, the site of the Alec Guiness WWll 'Bridge over the River Kwai' film, the Burma Death Railway, whatever you want to call it, who are trying to save the tiger from extinction.
The tigers I'm interacting with have of course been bred in captivity. They spend the evening and nights locked in cages but are released around 2pm each day to get a bit of freedom in a small canyon type environment where tourists can pay to get close, touch them, photograph them, be photographed with them. Of course you have to sign a waiver before you get in. The purpose of the venture is to raise money for an enlarged sanctuary so tigers can be bred without too close a contact with humans and be released into the jungle. Anyone getting accidentally eaten, who's family were to sue the temple for negligence, would defeat the entire purpose of the project.
I believe it's a fairly unique situation and I travelled to Kanchanaburi specifically to see the tigers rather than the bridge.
