To me, it's more like you're eating a family member. What if the cake was make to look just like your dog, your spouse or your kid? It's kinda sick...even though it's obviously just a cake, my brain doesn't want to cut into that, nor does it make me hungry- & full-disclosure, I LOVE cake & sweets!
People have been making cakes shaped like animals & things like clowns long before this- but none were realistic in appearance- they were comic caricatures. This takes some getting used to...at least for me. Maybe because of all these "reality" shows where people do kill & eat snakes, which is also something I don't want to see.
