The fur of rabbits is the principal component of felt. Wild rabbits prefer sandy, hilly terrain with lots of shrubs and woody plants. They eat grasses and herbaceous plants, and if those foods are not available will even eat bark and twigs. Rabbits have a remarkable way of getting the maximum food value from what they eat. In order for some of the vitamins to be derived, the food must pass through the digestive system a second time.
Wild rabbits live in colonies in a complex system of burrows called warrens.
They warn each other of danger by thumping their hindlimbs on the ground. When in danger, they either rush a short distance to cover or run across open ground at speeds of up to 50 miles per hour. Rabbits have an incredible potential to reproduce. Young rabbits are born blind, naked, and helpless in a fur-lined nest prepared especially for them. A female rabbit has the potential to produce 5-7 litters and 30 young per year.
