It's said that you can't touch a tiger's butt. But at 8:10 PM last night, at the Boai Pet Hospital on No. 121 Qingliangmen Street, a group of veterinarians not only touched the butt of a three-month-old Northeast Tiger transported from Anhui to Nanjing, but also subdued it, cut a small opening in its abdomen, and removed the small piece of bone that had subdued its own ferocity from its intestines.
