"I thought to myself, 'no, that can't be safe.' I go back and OMG it was a baby kitten stuck on the side of the freeway," Rob Acuna wrote in the Facebook post.
The video shows the kitten stuck between two ledges on the freeway. She was about to fall off the overpass, but the driver quickly grabbed her and placed her in his vehicle.
