Belgium's Planckendael Zoo has something to be very proud of. Five tiny Asiatic lion cubs made their public debut today, and the quintuplets are healthy, happy, and ready for mischief. Mom keeps the little rascals under control, but her own amusement is palpable in photos taken earlier today. Wild Asiatic lions are in danger of extinction, and only 411 individuals remain today. Breeding efforts like these help to bolster the reserve population as efforts to increase wild populations continue.
