There have been three reports of mountain lion sightings around Danville, Ca. Residents and hikers ar being advised to be aware of the situation. Don’t hike alone and do not approach a wild animal should you happen upon one.

Police are asking residents to be cautious after three mountain lion sightings were reported in the last two weeks. "This is just to educate the public," Sgt. Troy Francis said. "We don't want to scare anyone. They're just sightings."

The recent unconfirmed sightings were in unpopulated parts of the city. If a mountain lion poses immediate danger to people, pets or property, call 911, Francis said.

I remember a story in the LA Times years ago about a homeowner whose house backed up to the San Beradino mountains. He stepped out one night to call in his german shepard just in time to see a mountain lion jump a 6 foot wall with the 90 pound dead dog in its jaws. Lesson – these are very powerful animals.
