feral cats are EVIL. Predation for boredom's sake? Cull them early and often.
Bull. Cats have no sense of morality and only do what their instincts tell them to do. Small, domestic cats are almost identical, genetically, to their larger counterparts (lions, tigers, panther, cougars, etc.) and have evolved to be predators.
Interestingly, my own personal observations over the years have been that people who really loathe and detest cats are people who like to "control" things. Cats have evolved in this world to be predators and predators are focused animals, i.e. when they are hunting, they shut out all other stimulii and concentrate only on finding that prey.
