I agree with the poster who said to skip mothballs. They are terribly poisonous to everything, including people, and the stench from them is as bad as or worse than the cat urine. I have purchased a cat repellant from Walmart that worked quite well. It also had a smell, but not obnoxious, and it had to be replaced every time it rained, but it worked. It kept my own cats from pooping on the front lawn. You might also try citrus peels, as those are not too unsightly and won't be a horrible smell.

Cats lack the enzyme glucuronidase and cannot metabolize these oils, according to the "Handbook of Essential Oils." These oils can cause poisoning if ingested or absorbed through their skin. Spray these oils safely around your home, which will naturally deodorize pet odors while keeping cats off counter tops, plants or other areas. Look for these ingredients in commercially made pet repellents or make your own with them. Use these natural oils alone or in combination with each other to make a custom scent to repel cats.
