Be more specific is your question. A newborn is different ages at different times. Just like a human!

When the mountain lion attacks Little Ann and Old Dan... the second time :)
The oldest known mountain lion was Scratch who died just two months shy of his 30th birthday. Prior to Scratch, who lived at Big Cat Rescue in Tampa, FL, the oldest known mountain lion had been in the Guinness Book of World Records at the age of 23.

Cougars usually stay with their mother until they are at least 2 years old.
The Old Man of the Mountain in New Hampshire is gone. He was made of Granite.
Lion Feuchtwanger was born on July 7, 1884 and died on December 21, 1958. Lion Feuchtwanger would have been 74 years old at the time of death or 131 years old today.
The mountain lion has no natural predators. He's pretty much left alone and most will die of accidents or old age.
Less than one day old.
Old Dan's entrails (intestines) fall out from a wound the lion gave him, and Billy tries to put them back in, and his mother sews the wound up. It isn't enough and he dies in Billy's arms.
Old Dan in the book "Where the Red Fern Grows" dies while protecting Billy during a violent encounter with a mountain lion. Despite his injuries, Old Dan continued to fight until the mountain lion was defeated, showing his loyalty and bravery until the end. His death is a poignant and emotional moment in the story.
The book: "Where the Red Fern Grows" talks about a mountain lion about two times. First part of the first half of the book talks about him acquiring the two individual pups and camping in a cave for the next morning. But a mountain lion disturbs his sleep by shrieking and the two pups make an effort to go up to the entrance of the cave an howl with the mountain lion. The second part of the book is when the mountain lion hurts Old Dan and later dies. Then Little Ann dies after because of grief.I don't know which page you want but I have both parts.Page 45 is when he buys the dogs and hears a hellish roar though he thought it was a woman screaming at first.Page 224 is when he encounters the mountain lion giving a description of how he looked.It's 179 pages away from each other.Hope this helped in whatever your doing!
