I am NEVER without FRESH WAVE in my house! I have 2 dogs and 4 cats that are inside/outside and this product is a life saver because it reduces/eliminates pet odors. I have asked multiple people if my house reeks of pets and everyone says it always smells great! It doesn't mask odor...it eliminates it. It also works well if we cook fish or bacon, which can linger! I buy the large refills and pour a little into decorative containers and put them in each room. This stuff WORKS!
