Orange peel is probably the most well known natural best cat deterrent. However, results seem to be hit or miss. There is a stronger option. Many people who have been plagued with feral cats on their property have used (diluted) as a cat repellent spray for the yard.

The only downside is that you will need to re-spray the area after rainfall or around once a week to keep the fragrance fresh.

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. I kept stray cats from spraying the front of my house by splashing lemon scented Mr. Clean over the urine spots. This would work on fence posts, or tree trunks.Boundary Indoor/Outdoor Cat Repellent works as an effective training aid in and around the home to repel cats from areas they don't belong including furniture, carpet, trees, shrubs, garbage cans/bags, and other "forbidden" areas.

You can also buy cat repellant at hardware and likely, pet stores. It works as well, but has to be replaced after every rain. Do not use things like mothballs. They are poisonous to everything, and smell worse than the cat smell. If the cats are spraying their scent on the house (which they may be doing, as that is much stinkier than just pooping in your flower beds) try splashing some lemon scented cleaner on the spots. I did that one winter, when it was far too cold (-20) to be washing the spots, and it seemed to deter the cats and nullify the odor. You might try orange or grapefruit peels as well, as I think it is the citrus smell that deters them.You should never spray an essential oil of any kind directly on a cat to repel it. 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.
