I have 3 cats, 2 domestic & an abby. Layla used to pee on the floor in front of the back door. I tried all kinds of things. Eventually I visited Jackson's site and bought Safe Space For Cats plus the spray to eliminate odors. After about a week of use she stopped peeing and has not peed since then. Also, the other week, I had to bring 1 cat emergency to the vet. because she smelled differently when we got back the other 2 started really hissing at her. So we sprayed safe space. Great Product.
