because its not a name and shame, its a general discussion on the amount they charge to rehome a ferret. if you want to know the rescue PM me and i will tell you.
IMO if you are paying to rehome a ferret it should be a donation unless they have paid for the ferret to be neutered. if you pay 20pound for a neutered ferret then obviously that is cheaper than paying for it yourself but it should be your choice if they are neutered or not and if they are already neutered, your choice to get them.
like has been said, what are you going to do if you rescue a ferret, turns out to be a crackin
