Query: Didn't work - but I had to try it

After dealing with my cat peeing on the dining room floor for months, I bought this product out of desperation. I was impressed with the positive reviews and figured it was worth a shot. Unfortunately this product did not work. Actually, I can't say there was any effect at all.But, obviously it has worked for some people so I'm glad I tried it out.
