Dice Against Mice

The feud between mice and cats is as fierce as ever. You (a cat) need to settle this. You must beat a mouse in a game. You must guess if the combined total of your two dice is lower or greater than the mouse's dice. This won't just be an absolute guess, you can look at either your dice or the mouse's dice to help make your decision. Guess right 3 times to win, however, if you guess wrong 3 times, the mice will win.
