I've been using this for years. It's great for protecting the litter box especially from cat pee that is up against the side walls, front or back of the box Cleaning the area is much easier. Only have to scoop and spot clean with a damp paper towel, then re-spray just the area that takes the hit. This makes it much easier to remove the soiled litter; because it doesn't stick to the box. When I do a monthly wash and dry of the litter box, I will spray the whole box before I refill it with litter.
