I have 12 cats and 10 litter boxes. I still get some inappropriate peeing. I have always used Simple Solution and had great results. They have a formula for cat spray and urine that hasn't failed me. I even use it on vomit spots to get rid of the odor and stains. Just be sure to soak the spot and leave it to dry.

My cats like to spray in the kitchen so it drips behind the shelf over the washer. After I wipe it off, I spray the crack with Simple Solution.

Laminate flooring is beautiful, but will lift at the edges if it stays wet for very long. I have edges lifting where someone drooled and I didn't see it in time. I just put hardwood-look vinyl in my rental. The renter said she liked it better than the laminate in another room. I do too. I will definitely be putting it in my cat room this fall. Vinyl has come a long way from the old days.
