corvus: I certainly believe in all it's advantages, but I'm having a moment of "who can be bothered?". I guess with working full-time and an hour commute each way, and factor in trips to the gym and all the rest, I'm discovering that there are not many hours in the day to spend with my animals, and those hours I really just want to watch them be them and love on them and play with them and take it easy.
"play with them"? Clicker training should be a game. It should be fun for both of you. The times my own animals have just done something totally cute and unexpected and made me laugh out loud. You want to just let them be them? Try the box game. Just watch them "be themselves" - watch them discover this new object and interact with it... all you have to do is CT occasionally. You don't even have to have a goal in mind. You might train most things as you go, but if ever you want to use the click for a specific purpose, it's there and primed and ready to go, and KT understands the rules of the "game".
Do you ever just chill out together while you watch TV? What do you do
during the adverts? 
THAT'S the best way to clicker train. Short and sweet, that's the ticket
