Although my big ol' tomcat has plenty of different cat foods to choose from, he still eats a few rabbits (mostly little babies) now and then. He will eat the whole critter. I watched one day as he crunched up the skull and contents of a baby rabbit. Gross.
I liked my grandfather's stories from when he fought in WWI -shooting the enemy people and sometimes getting spattered by body parts. Had an uncle served in the Korean War -he did not want to talk about some of the awful stuff he witnessed there.
