This product is magic. for my cats it not only smells good and don't need more than 1 spray pump, but it also acts to sooth the cats , creating a calmness in them somehow. I will definitely buy more as this begins to run low, love this product. Works fantastic for odor control and seems like it is not just masking. highly recommend this product!

Fabulous product

Oh wow this smells great! We take trips to relatives at times with our dogs, and the guest room can begin to smell like the dogs; this makes it smell better (less embarrassing). It smells great, it's small and thin and can pack easily, no leaking noted, medium strength which I like as it's not overpowering. Great value. Recommend.
