What is "clicker training" for cats?

"Clicker training" for cats refers to a training method based on conditioning: the clicking sound is used to tell the cat it has done something right.

A clicker is a plastic box with a metal tongue that makes a clicking sound when pushed quickly. The sound is first associated with a treat. The cat is taught that every time it hears the clicking sound, it gets a treat. Once this is achieved, the clicker is used to identify the wanted behavior.

A clicker is a clear way of communication, and it speeds up training. The clicker is used in every instance that good behavior happens: if teaching the cat to sit, click the clicker the instant it sits and follow up with a treat.
