Sir: R Burfoot writes about the ethics of mink farming (letter, 10 March). Does he know of anyone who will actually "open the cage and see it bolt for the freedom of fresh air"?
If he does, he is perhaps ethically obliged to point out to them that the mink is an enthusiastic carnivore. What it is bolting for is more likely to be a meal off our native small animals and birds, or their young, than fresh air.
Whether or not it should be farmed for fur, the mink is not a nice animal or a friend to others. We do not want it in our countryside.
