What does a young rabbit born at the same time as others in a group called?

The term that specifically refers to a young rabbit born at the same time as others in a group is "kit." Kits are the newborn rabbits from a single litter and are usually dependent on their mother for nourishment and care during their early stages of life.

A litter, on the other hand, is the term used to describe the entire group of kits born at the same time, not just one individual. The usage of "pod" generally does not apply to rabbits, as it is more commonly associated with marine animals like whales. A calf refers to a young animal of cattle, making it irrelevant in the context of rabbit reproduction. Therefore, the term that accurately captures the essence of young rabbits from a single birth is "kit."
