We use Nature's Miracle. It even gets skunk off the dog. I believe they make a solution just for the feline accidents. We just use the gallon jar we got for the skunks. Did I mention that my dogs are stupid and chase skunks???? lol
The first time we went camping, our cat left presents on DH's side of the bed. Guess he showed us how displeased he was. Nature's Miracle took it out.
