Bracketing-out the fact it's a Russia-related story (tigers don't really have a nationality) it's kind of amazing, if true.

120 Miles of Russian Forest Couldn’t Keep These Two Tigers Apart
Boris and Svetlaya were raised together as orphaned cubs, and then reintroduced to the wild separately. But Boris went on a trek that surprised the researchers who were monitoring him.
The cubs, Boris and Svetlaya, had been rescued from the wild as unrelated 3- to 5-month-old cubs in the Sikhote-Alin mountains, the animal’s main stronghold. They grew up in captivity and were released at 18 months old. The cats were separated by more than 100 miles apart with the goal of expanding the distribution of released tigers as much as possible in the Pri-Amur region along Russia’s border with China.
The scientists tracked the cubs until, more than a year after their release, something strange happened: Boris walked over 120 miles, almost in a straight line, to where Svetlaya had made a home.
