Theres no myth about it, It is what me and the other fella said, A different term for albino
It's not a term for an albino ferret at all lol. A greyhound ferret is supposed to be a thinner, more mobile and athletic strain of ferret. These agile ferrets do exist but i dont think they are that much different from normal ferrets that they need a different name to categorise them. It's nothing to do with the colour. Obviously ferrets have different qualities about them,but a ferrets a ferret.
