I think some of that article is downright lies, it certainly doesn't apply to the majority of animals raised for their coats. Take Down for example - there was documentary about it only last year, where the farmers provided shelter and warmth for the ducks and harvested their feathers when they returned each year. As geese and ducks pluck their own down to feather their nests, those are removed and they are provided with warmth and shelter in its place. I saw one about the prized goats in a south American village, their soft coat is removed and they are given a garment to wear instead. I'm not saying all animals are treated as kindly - for example angora rabbits in China being plucked or shaven rather than combed - but that article only shows the extremes, which to me is the equivalent of saying that all children are neglected and beaten.
I love cashmere, but I do think that you get what you pay for. I have some amazing pure cashmere jumpers and tunics, but I have others that bobble badly and I use a little comb thing to de-bobble them before they are put away. I find that my moths prefer my merino wool jumpers to my cashmere, no idea why. My answer to the problem is to hang all of my woollens in one wardrobe and spray it all with fly spray once a year. I do have moth balls for a drawerfull of my favourite jumpers, I hang any up that I want to wear overnight, preferably outside, and then they are fine. I often buy them a bigger size than I want, then wash them and try them on still damp, at that time it is possible to pull them into shape if they have shrunk. After that they are washed on a cool wool cycle.
I have found that even some companies such as Pure vary quite widely as to the quality of their cashmere. However - once you have got into the habit of wearing it, nothing can ever feel as good again.
