Listen, I’m all for having cats around the house, but this is a little bit off the scale. I’ve dealt with cougars around my house before and lost good dogs in the process. So unless there’s a very good reason, I’ll kill a cougar if it gets anywhere my house, considering what it could do to a kid or even an adult if it’s hungry. This guy wasn’t a loser for killing this cougar, he was acting like a responsible adult who was protecting his family from a top-tier predator.
Relocate it.
