Hey friends, I need help! Last week a neighbor's cat somehow got into our house without our knowing and was here for a few days before we found it. Don't ask me how it got it, we haven't figured that one out yet! The cat peed/sprayed all over the upstairs of the house. We actually thought it was our cat making the stink and took her to the vet. The smell is awful and I can't seem to get it out. Any recommendations?
