Power struggles between you and your animal pal are inevitable at the beginning of the week. Don't fight the small stuff between Monday and Wednesday; bigger battles may be ahead, and you'll need your energy! Your daily routine becomes less dull toward the end of the week, when an exciting event or new person enters you and your pet's lives. Moodiness on Sunday can ruin predetermined pet plans. Cancel if you must, but try to reschedule as soon as possible.
