Query: IMHO, it doesn't work

My cat actually ruined a bookcase by peeing on the carpet next to it. I bought this product and Feliway, the product recommended to keep the cat away from the spot.The Anti Icky Poo said to first clean any spots with carpet cleaner. The Feliway, which I bought (as recommended on this site and others) to keep the cat away from the spot, said that cats will be drawn by commercial carpet cleaners, so which is it? I tried saturating the spot with the cleaner and then blotting. The cat came back and peed on the spot that I had cleaned. I tried cleaning it and simultaneously spraying the Feliway. She did it again. This stuff is expensive and it didn't work AT ALL. I am considering having the cat put down at this point. I live in a rental and I will be charged for this.
