I thought the pics were fascinating. I have no problem at all seeing this kind of stuff. Never have. If things didn't kill each other, we would be over run with rabbits, squirrels, deer, etc. I guess I'm desensitized to it having spent alot of time on my grandparent's farm where you see the circle of life on a regular basis.
When i worked at the zoo back home, I worked in the reptile house and we fed dead (dethawed mice/rats/pinkies) to the snakes. I always loved watching them eat. It's very interesting how far they can actually open their mouths. And they only eat like once a month!
