There's a big difference in my mind..........I could not go out and wring a pup's neck and skin him and then throw him in my pot to eat. I could (and have) done the same to a chicken though, and would again if I had the chance to grow my own.
Different emotional attachment. What would you think about cutting up a cat on your plate and dipping it in sauce and savoring the flavor? I would think the very idea is outrageous to you (and me, and most people in the western world at least) but yet it's nothing to do the same to a cow, pig, chicken, goose, fish, deer, lamb, I could go on.
There IS a difference to any person who eats meat. And if you are one of those who eats meat, you cannot say there is no difference in your mind unless you are willing to eat dogs, cats, hamsters, whatever kind of "pet"
