Clicker Training For Cats, Karen Pryor
You don't hear much about training cats but they do learn things. Sometimes it's cute, like knowing when you pick a laser pointer it's time for a game. Sometimes it's not cute, like scratching the carpet will get you to open a door. Clicker training is about using positive re-inforcement to encourage certain behaviours. Later on these behaviours can be extended or chained together to make something more complex. This was fun to read and I'd like to see it in practice some day.
