Boulder, Colorado, Oct 19: Gail Loveman's 11-year-old cat named Zeus usually stands tall and hisses when he sees a squirrel outside his owner's home.
He wasn't as much of a tough guy when the animal on the other side of the glass was a mountain lion.
Loveman tells The Denver Post the encounter lasted about five minutes before the mountain lion wandered off from her house near the foothills west of Boulder.
Loveman says she was in her home office last Thursday when she heard a noise and turned to see the mountain lion on the porch.
Zeus entered the room and walked to the sliding glass door for a closer look while Loveman snapped photos.
Loveman went upstairs and spotted a second mountain lion. She says both jumped a fence and left.
