Most: other canids of similar size to wolves.
Least: very small dogs, insects, small birds.
Two Siamese cats, Nala and Piewaquet. Two very different individuals.
Well, this is the UK, so there is no "wild". I do occasionally see fox, rabbits, mice, rats and deer.

Yes, and I'd extend that interaction to inanimate objects too.
No, though I've read research on this.
Not exclusively for fur/leather, but having killed an animal for food I'd be happy to use fur/leather and bones too. For me the distinction is not in what the dead creature is used for, but why it was killed. I find killing for greed or vanity abhorrent.
No, but given a real need to hunt and kill, I suspect I'd find it exhilarating. That would _not_ be a reason to hunt again.
