This became a real dilemma for me when it came time to eat Easter candy as I always received a chocolate bunny. For awhile I would just stare at its animal-likeness. Eventually, my desire for chocolate became too great and I nibbled a bit of the ear. As I ate the ear I then thought about how the bunny would have been in pain from my hesitation as he lost an ear (I thought about it being alive while its ear was eaten), so going in the absolute opposite direction I decapitated it and ate the head. Once the head was gone, I was okay eating the body because it was "dead" and no longer in pain.
I systematically consumed gummy bears in the same fashion, severing their heads first so they wouldn't feel pain when I ate the rest. I felt incredibly guilty about it each time and consistently faced a moral dilemma over it.
Interestingly, I never had a problem eating animal crackers. This is likely because animal crackers never actually looked like animals.
