I would not kill or eat companion animals, or dolphins or apes. Or whales.
I'm down to just a little piece of chicken a couple of times a week. I wish I didn't eat animals at all. I would be a vegan if I could. (I'm working on it.) I was good with the chicken until my cousin sent me a picture of her pet chicken and described how affectionate and playful it is. *sigh* I don't want to kill and eat things that show evidence of being able to love.
Oooh. Yeah, I could never eat a primate of any sort. Way too close to being human.
As for dolphins...well...the little girl inside of my goes "WAHHH" not dolphins! Then again, I think cows are adorable but as soon as you serve one cooked in a bun or slathered in BBQ sauce I'm all over it, so I can't make any guarantees.
I wouldn't have a problem with eating dog, but I probably couldn't kill one.
