Well, I do. When I die, I want every salvageable organ and tissue to be used to save other people's lives that are dieing if they don't get X organ transplant.

About the cats, if there was a sure-fire way to prove they didn't die just to be dissected then I would be all for it. If the school board made sure somehow that the cats either died of natural causes or were euthenized at a shelter after they would have been anyway then I'd be happy. The average city shelter euthenizes 5-10 healthy cats a day because they just don't have room for them all. If they had to go to die at least their bodies could go to good use.

I don't know if the cats care what happens to them, because no one can ever prove or disprove in life after death, but I believe there is nothing after death, which is why I want my body to go to helping other people live after I am gone.
