Well my brother doesn't have a savannah but we did get some "dog" training clickers and used some of the techniques discussed above, treat reinforcement and play reinforcement and it seemed to work fairly well. My brother's cat will eat whenever the opportunity is presented so treats really were good motivation as he doesn't get them very much. I will say that after a week or two we stopped giving treats and he continued to do some of the things we were working on with just a click. I don't think we ever transitioned into no clicking, except for sit, the cat will sit on command (raising a full fist up), but a lot of savannahs learn this pretty quickly without a clicker.
