Fetch: grab the toy if they play with it and it ends up close by, use verbal reinforcement
Names: the cats recognize everyone's name in the hous thanks to reinforcement learning
Locations: the cats know where I'm going and can beat me there because I tell them where I'm going, sounds like reinforcement learning again?
Activities: set phrases like "let's go", "come on", "let's get some food", "jump up", etc, all by reinforcement training.
Paw-touching: slowly touch more and more often, for longer, until nail clipping is a breeze. Hmm... Might be reinforcement training again.
To end bad behaviors, hiss, it's a built-in "no" for cats.
