Ha! i am sure you also saw the pet magazine on Vox TV ( not related to Fox) with that lady Birga Dexel who helps owners with cat problems. I see it every saturday and in many of her stories the cat is underplayed. Like that little boy who kept chasing his older sister so much that she had taken to living under the bed. Or those two black guys who really shred the apartment to pieces ( including opening and raiding the fridge) when their purrson was at work.
I was also thinking of starting with clicker training but I may be too lazy However do you remember Faramir, the Swiss Aby kitty who was also a friend of Randy's ( Mango's dad). Faramir did the most amazing tricks like balancing on a ball and giving his little paw. I think he also got clicker training. It might help Orion who right now sits under the sofa because he does not want me to write but to play. I am fairly sure Birga has videos on youtube about clicker and Faramir may as well.
