Overview:The cubs are half grown and still pretty playful but it's time to learn the hunting and fighting skills they'll need as adults. Play fighting erupts between them - it looks nasty, but their claws are never drawn. The young tigers have huge appetites and their mother must hunt successfully most days to satisy them. When they're not eating, playing or fighting, the cubs sleep - and tigers love water, so a cooling water hole is perfect on a steaming day. The spy cameras show that this wallow is also a magnet for a whole array of other forest animals, including wild boar and sloth bears. The cubs are starting to behave as individuals and take personal hunting tuition from their mother. Then disaster strikes when both their parents are injured, and a rogue male tiger puts in an appearance. They still have a lot to learn.
