I only found two companies that have a Laundry additive to take out odors, specifically cat urine. Zero Odor works & you do not have any odor to the items washed with it. It works , nicely! I use it on all my cats bedding, towels that they have been on. Its a great product that is true to it's use. I use other great Zero Odor products & have found it's easier to purchase directly from the company than go through a store front . You can get the sizes of product you want, large! So I am one Happy Customer & recommend this product . Zero Odor is true to their words! Products arrive timely & safe! Mahalo Nui Loa Zero Odor!
