When you think about it, people eat stuff that resembles something gross all the time.
Even a chocolate bar can resemble a poo log, but people love chocolate bars. Rice can very well resemble...lice. Someone in my highschool once said that the mashed potatoes were made with glue, and supported his argument by putting his small carton of milk in the potatoes and picking up the tray with it. You could even argue that squash when mixed with butter and brown sugar, resembles puke.
Then again people eat meat all the time too. And meat is little more than the muscle tissue of an animal, and you get to eat their blood veins and such. From that perspective, it doesn't sound very appetizing. And yet, meat tastes good.
And sadly, I still havn't made the recipe yet. I mean to, but I might have to wait until I move out. I don't know if my grandma would let me make it, and I don't think the presentation would be right with just a regular cake pan.
But needless to say, the point I'm making here is just because it looks gross, doesn't mean it is. Granted, some of the candy they come up with for Halloween...like the human fingers and feet, and the candy noses with the snot coming out of them...now those gross me out.
So I guess I can't really blame people. But living with so many cats, the look of a litter box doesn't bother me. But the smell on the other hand..
