Mountain lion cubs lucky to be alive after mother killed

A group of mountain lion cubs are lucky to be alive after they were rescued while wandering all alone in a forest after their mum was killed.

The three ten-week-old cougars were on the brink of death when they were rescued by local game officials, because they were way too young to fend for themselves.

Oklahoma City Zoo took in the two brothers and their sister, and gave them Native American tribal names: Toho, Tanka and Tawakoni.
