Karis, an 11-week-old lion cub, plays among fallen leaves at Blair Drummond Safari Park in central Scotland on Nov. 20. Keepers report she also loves playing with cardboard boxes. At 5 kilograms (11 pounds) she currently weighs one thirtieth of what she will when fully grown, and although she currently lives alone in an enclosure with her mother, Teekay, she will join the rest of her pride in December.
