Kuzco is absolutely adorable! I'm sure he has you wrapped around his little paws.
For training methods, I learned that positive reinforcement methods are most successful. I also use the "ignore" or "withdrawing attention" method for some behaviors. When Max would purposely do something naughty for attention and wouldn't listen to a polite correction, I would ignore him or even leave the room where he couldn't follow. It takes all of the fun out of what he is doing.
