The Silver Fox Rabbit is truly a multi-purposed breed whose genetic make-up has never been divulged. Today the Silver Fox is critically endangered with fewer than fifty annual North American registrations and there is a global population of less than 500. The rabbit breed was recognized and a standard approved in 1925 by the American Rabbit breeders Assoc under the name American Heavyweight Silver. In 1929 the name was changed to the American Silver Fox and later to Silver Fox. Silver Fox are known for their docile and gentle nature. The fur of the Silver Fox rabbit is one of the most attractive and unusual features of the breed. It is extremely dense and 1 1/2 to 2 inches in length. When the fur is stroked from tail to head, it will stand straight up until stroked in the opposite direction. This trait is found in no other breed and greatly resembles the pelt of the silver fox of the Arctic.

The young begin to show silvering of their fur at about four weeks. The silvering process takes about four months to complete. The fur is the Silver Fox's most attractive and unusual feature.
