Jacci in responce to your question and statement about your ferrets, Marshall Farms is the only breeder that I know of that uses the 2 BLUE dots in their tatoo. There are some other breeders in Canada that do tatoo their ferrets. I had a few come into my rescue a couple of years ago from Canada that had a red tatoo and one with a green tatoo, but the one was an "F" and the other was like this "~". So the one with the 2 dots is deffinatly from Marshal Farms not Petersen Farms. WEASLE QUEEN [Posted in FML issue 5063]
