The breeding season for this species lasts from February or March until September, during which time they engage in mating to produce offspring. During this period, males establish dominance hierarchies and fight to secure mating priorities. Female eastern cottontails give birth to young ones, known as litters, after a gestation period of approximately 25 to 28 days.

Eastern cottontail litters typically consist of four to five babies, though they can have up to eight in some cases. The newborn rabbits, also known as kits, are altricial, meaning they are born without fur, with closed eyes, and are entirely dependent on their mother for survival. They remain in the safety of their nest, which is usually concealed in thick vegetation or underbrush. The mother rabbit visits the nest once or twice daily to nurse them. The kits open their eyes after around seven days and slowly begin to explore their surroundings.

During the growth phase, eastern cottontails go through various developmental stages before reaching adulthood. The kits start consuming solid food at around three weeks old, and by the age of four to five weeks, they become independent and leave the nest. The growth rate for different rabbit breeds varies, but generally, eastern cottontails mature quickly and reach their adult size within a few months. Notably, they experience a significant increase in size and weight during the first months of life, allowing them to better adapt to their environment.

Eastern cottontails do not show long-term mating relationships, and both males and females pursue multiple mates during the breeding season. This behavior allows them to produce multiple litters to maximize their reproductive potential.

In conclusion, the life cycle of Eastern Cottontail (Sylvilagus floridanus) rabbits consists of key milestones, from birth to adulthood. Their altricial nature demands parental care until they can survive independently. The breeding season offers ample opportunities for this species to mate and produce offspring, ensuring the continued existence of their population.
