Altadena Sheriff's Deputy James Matsuoka emails us that a "a full grown mountain lion" was spotted around dusk tonight (Wed., Nov. 16) in the area of Chaney Trail and Alzada road. Anyone walking their dog alone near dawn or dusk need to be extra careful and walk in groups. He also says that "pet owners who normally leave their dogs and/or cats out after dark may want to bring them inside for their safety."
