What is the common term for a young rabbit?

The common term for a young rabbit is "kit." This term is derived from "kitten," which historically referred to young animals in various species, including rabbits. The use of "kit" specifically for young rabbits is widely recognized in both everyday language and in more formal or scientific contexts as well.

While "pup" is a term used for young dogs and sometimes other animals, it does not apply to rabbits. "Lamb" refers specifically to a young sheep, and "cub" is typically associated with young carnivores, such as bears or big cats. Thus, the term "kit" is distinctly linked to young rabbits, confirming its status as the correct answer for this question.
