The Russian blue is actually considered a moderately active cat that prefers to start the day comfortably. One cannot say that of young representatives of this breed, because they can hardly be stopped once they get going. You can see that very well in this video.
Small safety note: When playing laser pointers with the cat, you should be careful not to shine it in the eyes, as this could endanger your eyesight. So that the game is not frustrating for her, you should always let her catch the point, praise her or give her a small reward.
