"The rare grey ferrets of Eregion, with their silvery grey coats broken only by black feet and mask, were unusally intelligent and were favored pets of the Noldor of Ost-in-Edhil. Growing to nearly two feet in length, they were amazingly quick and powerful, able to kill a much larger animal with their strong jaws. It was feared, however, that they were extinct by the mid Third Age."@en . "Silver ferrets"@en . .
