These are just horrible ideas. The cat is an animal. It's doing what animals do - patrolling an area it believes is it's territory. Until challenged by something bigger and tougher than it, it will continue to think this. Since slack's cats weren't able to meet that criteria, it's simply up to him to prove to the interloper that it isn't welcome and must forfeit this area. Super soaker or simple garden hose is a great idea. Arrows, shotguns, snakes, traps and the like are terrible ideas. I seriously hope you guys are kidding. Cats, like many other animals (including humans) are extremely territorial. That doesn't justify brutally killing it, just run it off and show it that it's territory doesn't include yours. That's all it takes.
