Wouldn't it be better to simply motivate the cat to get in the carrier with a can of tuna fish?
This is a very simple form of modeling the cat's mind, using that model to predict its behavior and choosing a course of action that results in the desired outcome. We do this for other humans all day and most of us never resort to brute force. I think it is pretty fair to imagine an AGI that is both better at modeling human minds and better at evaluating possible actions and their outcomes.
