Go to your local pet store and get something called Natures Solution. It comes in a variety of sizes. I believe there is a spray bottle. It needs to be used full strength whenever possible. Spray it on your hoops and your odor problem will be gone. We've used it on carpet, clothes, etc and have had excellent results. We had a cat who became rather 'territorial' when we got another cat. Eventually we found her another home, but were glad for the discovery of the Nature's Solution.
