Rabbits do not hibernate. They are crepuscular animals, which means they are most active during twilight hours. Wild rabbits burrow in snowdrifts or use unoccupied underground dens of other mammals during winter and rest under brambles, overhanging limbs and old farm equipment during balmier days of the year.
Most rabbits eat tree bark, twigs and other woody plant parts they find during the winter season. Rabbits have an unique digestive system that enables them to survive the winter. For instance, if need be, they can feed on their own feces when food is scarce. Domesticated rabbits, while able to withstand the freezing cold, still require extra straw or bedding for insulation and protection from rain and wind.
