Video taken early Tuesday morning shows the big cats making themselves right at home on the front lawn of a home on the 600 block of Camillo Road.
Sierra Madre police said patrol officers responded to the scene and escorted the mountain lions out of the area.
"When the officers got up here they did recognize them as the mountain lions that we've seen before up here," said Capt. Larry Giannone "Usually, you know, they try to run, scurrying back up the hills, but as I watched the footage from our patrol camera, they simply were just walking along the side of the roadway looking back at the patrol officer and then went off to the east."
No injuries or damage were reported, and there were no reports of missing pets.
Some residents said they are not too concerned by the sighting of mountain lions comfortably lounging around in the neighborhood.
"It's their home, we choose to live here so you have to be comfortable with them around," said resident Roubina Gourdikian.
Fish and Game officials said the mountain lions probably came into the area looking for small animals. They said it is not uncommon for mountain lions to roam foothill communities, like this one, at night.
