Query: Just an Expensive Outlet Device

I have 2 cats that fight/play, especially at night, so I got it to help me sleep at night. With a loft style apartment I cannot lock the cats out of my bedroom and got this product in hopes they would not trample on me when playing chase or scrimmaging late at night. After 2 weeks of having the plug-in placed by my bed, there has been no change to the late night feistiness. I would not even consider this a room freshener as stated by a previous review. I smell no fragrance except when a few inches away from unit. I gave product 1 star as it may have had a small undetectable change in behavior.
