You can eat animals?!

Tonight Leanna was asking me questions about Wilbur and Charlotte (from Charlotte's Web). She wanted to know why people wanted to eat Wilbur the pig. And how could Charlotte save him? So I'm trying to explain to her that pigs are where ham comes from. And I'm explaining that they cook the pig and cut it up to eat it (yeah it's sounding really gross to me to). I can tell it's not quite getting through though. And then all the sudden she exclaims, "You can eat animals??!"
