A male rabbit is called a buck, and a female is called a doe. A baby rabbit is called a kit, which is short for kitten. Rabbits have a gestation period of around 31 days. The female can have up to 12-13 kits, very rarely litters as big as 18 and as small as one. When the doe gives birth her babies are collectively refered to as a litter. Some people have rabbits as pets. Rabbits are also raised for their meat. Rabbits are of a different biological classification than hares.
