One of the big Canadian Farms uses an "X", another uses a red dot (Triple F Farms isn't the only red dot.) Path Valley does not tatoo. I would personally love to see more ferretries microchipping, even if it does add a few dollars to the cost of the ferret (I honestly think people wouldn't care). It would certainly help us shelters determine age, ownership in case of found ferrets, and some history on the ferrets. There are a couple of shelters who are now chipping all ferrets who come in. We haven't gotten there yet, but are looking into it. -Anne [Posted in FML issue 2249]
