Just thought I'd clarify that I'd never use such for a fursuit for several reasons. I mostly use the real animal crafts and such that I have for pagan events or spiritual purposes, though I'd never condone killing an animal just for its fur or other parts. Was just curious as to what everyone thought, considering I've seen some real animal parts (like the aforementioned fox tails) for sale at furry conventions.
There are a lot of interesting points of view. Merely having animal parts doesn't bother me depending on where they came from. As to the person who mentioned human parts, I honestly wouldn't mind having, say, a human skull in my collection so long as it was legally acquired. Yeah, many might consider it to be poor taste, but I'm weird like that.
It's also kind of interesting how we view certain animals as being "above" others. As in, we care about predators, but food animals seem to be fair game to several people in this thread. I wonder why that is. Is it because more of us identify with canines and felines? Do people with deer, cow, or other hooved fursonas feel differently? How about herbivores that we don't consider "food animals?" Would you treat a horse's remains better than a cow's remains? They're similar animals, but we view cows as food animals, whereas in the United States, we don't typically eat horse meat.
