That "your mommy kills animals" pic reminds me of our grandson, Marshal Punky. He (who hadjust turned four a couple of months ago) and his 3 year old sister were taken out to see the buck that daddy had shot. They petted it saying "poor deer". Daddy explained that they were going to cut it up and cook it to eat. Marshal punky says " Mmmmmmmm. Delicious" Yes, he is a carnivore like the rest of us. LOLL He can pack away meat like a T-Rex (in his words)
Your grandson sounds like my four year old. He is against killing baby animals, but not adult animals. At a recent feast I acquired a taste for lamb. When I would mention getting some he would say he doesn't eat baby animals. He realized the lamb at the store was already dead and that wasn't changing. I came back from the store saying I had thought of getting lamb chops, but had not. He said, "But, I want to eat lamb chops."
