MissD:I'm afraid that serial killers do start off on animals and progress to people (either children or adults). In most cases, they progress on to children then on to adults.

I really do not understand how this person or persons actually sleep at night. Perhaps they sleep quite well and don't care or do not understand the horror and pain they cause to these helpless animals. If they can do this to animals they are perfectly capable of hurting people and thus, in my own honest opinion should not be around in public but should be locked up to never see day light again. I seriously, feverently hope that this person or persons do not have any animal of any kind in their ownership.
