It may not stop the activity but it should over time decrease it and maybe stop it. It will take a little while for all the hormones to level off. When Vixen was spayed she was her wild crazy and aggressive self. It took her a couple of weeks to start settling down. She is now quite calm and much changed from before her spay. Of course she still has her crazy moments. But I think give it a little time and you will see the activities decrease and possibly stop all together.
