Turns out that automatic doors can be opened by mountain lions, and I’m guessing that the builders of this condo complex in Vail didn’t anticipate that as a possibility.

The first video shows a mountain lion triggering the automatic doors at a Vail condo complex. He strolls right through the lobby and then down the hallway.

That’s where the 2nd video picks up the lion meandering up and down the reset of the hallway.
