PETA can suck my nads.

It's about the people involved.
I occasionally go to livestock auctions. If I saw anyone handle a crate of chickens, ducks, guinea pigs (or whatever) in the fashion those people were handling those dogs and cats, they'd be gathering up their teeth. Odds are that I wouldn't get opportunity to get to them first because anyone there would do the same.
That tends to make me blame the shytbag culture that raised those people.
So far as kitties and puppies being used for coats, I fail to see the difference from using cows and mink, muskrats or rabbits.
