I know Nobo is making your life a misery but I think Andy's system would just end up with an angry, resentful and fearful cat. How can you improve your bond with a cat if you treat them like that?? I just don't believe cats respond to punishment in the way that kids and dogs do. I wouldn't even do that to a horse. And I would never scruff a cat. It terrifies them and is very painful.
To "discipline" my lot I always use same words, same tone of voice, for each cat. With some of mine I've barely had to whisper "no" in a stern voice and they stop immediately. With others I have to bark out "NO!" or their name, to get their attention. You have to learn what works with each cat and stick with it. Follow it up by removing them from whatever they were about to do, possibly into another room for a few minutes to break the moment, then let them back in before they start wreaking havoc elsewhere, and repeat as necessary. My Mo was a b*gger for doing whatever he could to get attention, good or bad, but he did learn my warning "nooooo" or "Moseeeees" in a low tone, which made him think and pause, and then if he decided to go ahead anyway he got the loud "NO!", or "MOSES!" followed by me removing him from whatever he was about to do. It didn't always work, but it certainly improved things a lot. He hated being shut out so was usually fairly contrite when I let him back in, and had usually forgotten what it was he was about to do that got him into trouble.
Good luck. I really do sympathise. You're obviously a great mum to your lucky pusses, but he really is determined to push the boundaries!
PS - he may be responding to your stress over the impending house move. Just a thought.....
