Don't laugh! At the clinic I used to work for years back, we had a pretty eccentric client who had come up with his own religion-- He explained to us that because of the tenets of the faith that he had decided upon, he felt very strongly that EVERY part of his pet should go with it to the afterlife so that when they were reincarnated, nothing would be missing. So whenever we removed ANYTHING from his cat, we kept it for him and sent it home. Her ovaries, her teeth, a tumor.-- everything! He planned to bury all the pieces together.
Your doctor might think you have some reason for wanting those.
