I've never seen one. But I'll check them out here occasionally: http://nationalzoo.si.edu/Animals/GiantPandas/default.cfm?cam=LP2
When giving the presentation at the Memphis Zoo, the presenter said that pandas are like bears in that they look all happy and cute but they can be quite vicious if they need to be.
Yeah, pandas are cute. Until they rip your head off in a fit of rage. Never trust a bear. Especially cute bears.
