One female rabbit is capable of giving birth to between one and 14 baby rabbits, also known as kits or kittens, per litter. However, the average litter size consist of six babies.
Rabbits breed quickly, and their gestation period lasts 28 to 31 days. Adult female rabbits can become pregnant again only minutes after giving birth. Ovulating rabbits are adapted to give birth to a dozen litters per year. Rabbits are fertile early in life, beginning to reproduce at the age of six months. Assuming three female rabbits are born to a litter and each birth six babies per month, then a small family is capable of producing over 216 babies in a single year.
