It may seem a little short fused, but I've little regard for discussing the deaths of people's pets as if it's a delight. I've even known a LEO that claims he "used to" love deliberately running over cats. Had I any real evidence, he would not have continued his profession, since Oregon considers such animal abuse a felony.
There are some that let an abnormal hatred for one type of animal or another blind them to their irrational acts. What they can't seem to consider is the cruel act of injuring or killing the animal they hate is not just an act directed at an animal they dislike. It is a crime also against the people that have developed love and a relationship with their pets. The delight and companionship they experienced with their pets is destroyed by some short sighted criminal that can't see beyond their own irrational hatreds. Men, women and children are often devastated with grief, sometimes spending days crying and worrying over a small little special creature that has become a part of their family.
