This product works! I have a female cat who is very picky about her litter box! She goes on clothes, shoes, beds, anything! So I use it as directed but I also pour in my laundry! I had bought a brand new mattress and she peed on it before I even got sheets on it! I sprayed this on it and it removed any smell and coloring! I’m hooked and will be buying the 4 gallon package this time!!
