Would you mind me asking who these people are that are releasing captive bred polecats into the wild here in Wales? That's the first I've heard of it, seeing as Wales' own native polecat population is healthy.. I'm not saying I don't believe you, but in my area there is absolutely no need for numbers to be increased by adding foreign blood..
