Ustin—one of Vladimir Putin’s three Siberian tigers—has moved from Russia to Heilongjiang Province, following closely behind Kuzya, who swam across the Amur River in October.
The Russian president released the three grown cubs in May, after they were rescued from the wild last year. They all have tracking devices, enabling Russian and Chinese officials to pinpoint their movements.
While local farmers recently tried to blame Kuzya for attacking a henhouse, Ustin is suspected of killing several goats.
However, according to experts, Kuzya prefers preying on wild boar.
There are thought to be less than two dozen tigers left in China where they are vulnerable to poaching for the black market.
