Here's an example, via BBC News:
A Siberian tiger released into the wild by Russian President Vladimir Putin has wandered across the Russian border and into China, according to officials.
The endangered animal, named Kuzya, was one of three tigers freed by Mr Putin in May.
But forestry officials said the big cat had now entered Chinese territory after crossing from the wilds of eastern Siberia in search of food.
Chen Zhigang, director of the Taipinggou nature reserve in north-eastern China, said that the tiger would not have to worry about finding food as cattle would be released into the reserve if necessary.
So Putin released a tiger as a part of a publicity stunt, and now it's hungry. But don't worry, they're gonna release cattle into the wild too for food.
What's he gonna do next?
