When I had my first cat named Oscar, it ripped the head off of a baby squirrel in the alley way in front of its mother, and then took the mothers leg.
It left a bloody mess.
And then this time in 4th grade, our cafeteria tables are outside, and I saw people looking around my classes table. I moved through the crowd to see a bunny sprawled across the table, guts open, with blood paw prints around it.
I had to eat on that table 3 hours later. Blood stains don't always come out easy. But then again, much worse for the guy cleaning it.
