This product does work well!
I have 3 cats that have never gotten along, one that has been treated for bad anxiety with three different options.
I bought TheraPet before changing houses because I worried about how they would handle the move, it was a smart choice!
The cats were calm during the transition and settled into the new home in just a few days.
They are now more relaxed, and there have been fewer fights among the three.
I can tell when it's time to get a refill, as the cats start misbehaving again when it runs out.
Compared to other similar products, I find TheraPet to be the most effective and the best value.
