An old PDF I found and realized it had never been mentioned in any posts here. So, here it is…
"The animals we eat are individuals capable of experiencing pleasure, fear, and pain. Think about dogs or cats you've come to know. They can feel sorrow, joy, terror, and other emotions. So can animals we don't know so well, like chickens, cows, or pigs. All of these animals, whether chicken or cat, pig or puppy, experience a wide range of emotions and value their lives. Yet, the animals who we eat are treated so abusively in this country that similar treatment of dogs or cats would be grounds for animal cruelty charges in all 50 states."
