Hope for survival: Litter of adorable mountain lion kittens found near Los Angeles.

Biologists with the National Park Service discovered three 24-day-old mountain lion kittens in the Simi Hills, west of Los Angeles. The kittens, identified as P-113, P-114, and P-115, must now survive in an increasingly urbanized area of Southern California. Mountain lions in Los Angeles County are significantly threatened by the development of roads and cities, with vehicle strikes being a leading cause of mountain lion deaths. The new kittens are an "encouraging" sign for the small population of mountain lions in the area.
