Rabbits, or bunnies as we often refer to them, are well known for their prolific reproduction. Rabbits reach sexual maturity as early as 3.5 months of age depending on the species, with pregnancy only last about a month. A rabbit may give birth to as many as 12 kits (baby rabbits), and can get pregnant a mere 24 hours later!
