Puma Treed by Hound Dogs (image) University of California - Santa Cruz Caption Lion 7F, an approximately seven-year-old mother lion, lives in the mountains above Los Gatos, Calif. She has had three litters of kittens in the four years since she was first collared. On this day, she was treed by trailing hounds so researchers could replace her collar before the batteries on it failed.
