This post comes with a content warning for a somewhat graphic photo of a tiger having lunch.
I've been to China a couple of times, but, of course, I didn't got to see a giant panda up close until I saw two of them in Scotland. Tian Tian (Sweetie) and Yang Guang (Sunshine) are on loan from China to the Edinburgh Zoo, and they're the zoo's leading attraction these days. Pandas sleep a lot, I gather, but while we saw them they were fairly active: eating some bamboo, walking around, and, of course, napping.
One of the guides told us that every available square inch of zoo grounds is planted with bamboo now. "It grows pretty well, it likes the rain," she said. Mostly they import panda food from the Netherlands, and will do so until their own crop becomes more established.
