WHAT? You are cruel.
Probably less so than you might think.
It is the responsibility of the cat owner to keep it from being a nuisance or damager of property to those around it. If the owner neglects said responsibility, and animal control is unresponsive, what's a property owner to do?
He really isn't cruel. The people who are cruel are those that let their cats outside to kill our birds. House cats are not a domestic species. People who fancy cats should keep them indoors.
Any cat that gets into my backyard is a target.
