I read the original post. The mice are not giving anyone any raises. The mice are not capable of human-level cognition, and do not occupy positions of administrative power in the company. The mice are just mice.

Your actual, human boss decides whether to give you a raise, what you work on, etc. He or she might choose to implement a policy that ties your assigment and your compensation package, in some indirect way, to the behavior of the mice (although to be more accurate, to what you do with the mice), but to insist that it is therefore accurate to say that the mice are your bosses and are making the decisions that control your career, is absurd.
