How do rabbit babies live underground?
Chris Packham visits a man-made rabbit warren to see baby rabbits being born. A scientist shows him how a thermal imaging camera detects heat instead of light and can be used to see which animals are the warmest. The kits (baby rabbits) have no fur when they are born, so they must huddle together to keep warm. The mother rabbit feeds the kits with milk, just like all mammals. Because it is warmest in the middle of the huddle, the kits change places to stay warm. When the kits are older, they start to eat solid food; initially, their mother’s faeces. This contains important bacteria that will help the kits to digest the tough plant material.
