Hi, I decided to try WBCL Zero Mess™ for the first time and my cats decreased their slips outside the litter box. Though I am on top of their situation and keep up their litter, seems they miss it at times. When I started using the Zero Mess™, I noticed less spills and more litter box cleaning, which is great as I know that they are USING IT A LOT MORE and not urinating on the floor. They are up there in senior years, so the best I can say is that I have three very happy cats, and it shows in their purrrrfect affection towards me.
