Geez Deb lighten up. So the guy likes to watch snakes kill mice/rats. Anyone with a problem with "snake people" will have the problem live mouse or dead.
You can't please the PETA folks hell they think you and I are "slave masters" for keeping pets. Their term not mine. Oh yea they think chickens should have the same RIGHTS as people.
Chickens have a "right" to a good fried recipe. Mice have a "right" to occupy the bottom of the food chain. I feed PK to all but one of my snakes a Carpet python who refuses anything but live. I do that for my convenience though not to please the people that eat carrots or anyone else for that matter.
If you wanted to define "rodent killing machine" a picture of any constrictor would do just fine. Nature is wise, who are we to question her?
