I frequently hear the misconception that a mountain lion lives in a certain den or hiding place all the time. In fact, lions who don't have tiny kittens are constantly on the move. When they manage to kill a deer or elk, they will stay close to the carcass for a few days.
When they've finished eating that meal, they move on to hunt for their next meal. This video includes an example of a mountain lion who visited a spot in the forest at least twice per day for about 3 days while he ate a cow elk that he'd successfully hunted. Then, he vanished, in pursuit of his next meal.
Over the years, a mountain lion appeared in this forest clearing about once every three months so his twice daily visits were extraordinary!
Check out the video of three days of a mountain lion "commuting" to and fro his feast. He's a big cat, and his behavior is fascinating to watch.
