There was some reference in the link that some mother pigs that were raising tiger cubs had been raised themselves by tigers. But most likely the piglets go the same way as other piglets in Thailand, to market, and eventually to someone's plate.
We really didn't doubt the story when it was e-mailed to us by friends. We were just surfing the WWW to find a direct link to a story which included the digital images and then post it on Mudcat. What we found totally discredited the original heart-warming story. But it's still an interesting story.
