How often can rabbits have litters?

Most rabbits are capable of producing litters frequently, often conceiving four or five times a year. This high reproductive rate is supported by several biological factors:1

• Induced Ovulation: Unlike many other mammals, female rabbits (does) do not follow a regular cycle. Instead, their ovaries release eggs in response to the act of copulation.12
• Postpartum Estrus: Does can experience postpartum estrus, which allows them to conceive immediately after giving birth to a litter.1
• Early Maturity: Rabbits generally reach sexual maturity and are able to breed at a young age.1

While this potential for frequent reproduction is common, it can be suppressed by environmental factors, such as a scarcity of resources.1
