I am also a cat owner and the best way to keep him behaving is plain and simple...WATER! Not only is it the most humane way of training the cat, it's also kind of fun too. I disagree with put vinegar in the water of anything that would harm them. I know your upset but hurting or killing an animal is just WRONG! It's the owners fault that thier animals are so distructive, you should set a live trap for the owners, not the cats.
