The Republic of Tuva is also home to big cats. In 2016, the WWF reported that a snow leopard had been caught on camera.
The story has not escaped the attention of the local authorities.
The Republic of Tuva's Office of Investigations announced it is investigating the girl's 31-year-old mother, Eleanora, for putting elderly citizens and a minor in danger. The grandfather was blind and the grandmother infirm. They lived in Saldam-Beldir - a "hard to reach place" in the words of the investigators.
She could face a fine or even a custodial sentence.
It also said it is reviewing the actions of the relevant child welfare authorities.
Siberian children have shown before they are made of stern stuff.
Last year, a 3-year-old boy spent three days on his own in a forest in the same region.
Even more remarkably, in 2014, a 3-year-old girl survived for two weeks alone in the taiga. She ate berries and drank water from rivers.
