What do you call a newborn rabbit?

A newborn rabbit is referred to as a "kit." This term is specifically used to describe young rabbits, and understanding this terminology is essential in animal science, particularly in the context of domestic rabbits and breeding practices.

The term "bunny" is often used colloquially to describe rabbits in general or to refer to them in an affectionate manner, but it does not specifically denote a newborn rabbit. "Cub" typically refers to the young of certain carnivorous mammals, such as bears or lions, and "poult" is used mainly to describe a young turkey. Therefore, "kit" is the correct term that specifically identifies a newborn rabbit in the context of animal husbandry and breeding.
