Bests & Worsts Reviews from Amazon

We are undergoing significant home remodel and repairs. I purchased this product days before to see if it would get us through. I had opened the box, and as life happens became distracted, putting it down on our hall bench without yet removing from packaging. Shortly after I found one of my cats like this... I say it works. :) All of my cats have kept (keeping to date) their sanity, as much as to be expected with loud machinery in the home. We have portholes through several walls, so they can hide from room to closed room at choice. I believe this product is helping a great deal. Recommended. I do wish is was slightly cheaper. This is enough to get us through the month, but with repairs exceeding that time frame we will need more.
