Junior 4-H Rabbit Knowledge Practice Exam

A dewclaw is a common term that refers to the extra digit on the inside of a dog or cat's paw. It is thought to have been used for climbing or gripping in primitive canine ancestors, although currently, it serves little to no function. A dewclaw is not exclusive to canines and felines though, as some ungulates and even certain marsupials have them too. As for the other options, rabbits do not have dewclaws, so option A is incorrect. Dewclaws are not used for defense, so option B is also incorrect. Option D is incorrect as dewclaws themselves are not a disease, but rabbits, as well as other animals, can develop conditions or injuries in their claws.
