A tiger that is believed to have roamed into China after being set free by Russian President Vladimir Putin may spend the winter in China, according to the latest investigation.

The big cat "Kuzya," tagged with a tracking device, is moving southward, further away from Russia, said Eugene Simonov, coordinator with Rivers Without Boundaries Coalition, a multinational, non-governmental organization, on Saturday.

"We have to prepare ourselves that Kuzya will spend the winter in China. The Russian experts have called for local Chinese not to feed the tiger with any poultry, which is vital to keep its wild survival ability," said Simonov, the Russian coordinator of the joint program to find the tiger.
