I know some (two) homeschoolers who found a cat dead in the road and boiled down the bones and put it back together for anatomy class at home! eeek.
In one of my science classes the first year of college, we did a lot of disecting...The only one I was queezy about was dealing with an eyeball, sticking a needle into it to asperate out some fluids to check. Most of the dissections were not much different than frying a steak or fixing some liver and onions for my dad..Never experienced an eyeball in home cooking...:O)
