In this clip from the BBC nature series "Tigers About the House," tiger expert Giles Clark from Australia Zoo introduces two rescued tiger cubs, Spot and Stripe, to their first grown-up big cat. The tiger who had the honor of being the first adult that the youngsters got to say hi to was Maneki, a nine-year-old female who had never before seen cubs. During the meeting, Maneki and the cubs immediately starting chuffing at each other, which is their way of saying hello. It's also used by mother tigers to comfort their cubs, a good sign according to Zookeeper Clark that Maneki (and the other tigers) will welcome Spot and Stripe when they're big enough. As cute as that was, I'm a bit worried to learn that tigers talk to each other like the velociraptors from "Jurassic Park." As if they weren't already scary enough!
