Female rabbits generally have six to eight pairs of nipples, arranged in two lines down their belly. However, the number of nipples can vary depending on the breed of rabbit. For example, mini lop rabbits typically have eight pairs of nipples, while Rex rabbits usually have six. Although both male and female rabbits have nipples, only the females are able to use them to feed their young. When a female rabbit gives birth, her milk is produced in the mammary glands and flows through the ducts to the nipples, where it can be consumed by the tiny kits. So, next time you see a mother rabbit nursing her offspring, keep in mind that she's got plenty of nipples to go around!
