Rabbits practice coprophagy. They rapidly consume large amounts of green plants during their dawn and sunset feeding times but plant material is hard to digest. One kind is soft and greenish in color. Vitamin C is absorbed during the second trip through the digestive system. The other kind of feces is the hard, dark colored pellets commonly seen.
Rabbits are very prolific if food is abundant.
Courtship behavior include behaviors such as sitting and staring at each other, chasing, and wild leaping. Male rabbits will breed with any female they happen to meet but females only breed with one male. Rabbits are born 28 days after mating. The female mates again shortly after giving birth. This can result in several families per summer.
