DIY Cat Repellent Spray: 3 All-Natural Recipes That Are Safe for Indoor & Outdoor Cats, via The Secret Yumiverse
Determine whether you need a repellent for dogs or for cats. If it's cats, stay away from ammonia -- to them it smells like pee and it will encourage them to come around more often, peeing again and again on the spot. Dogs, on the other hand, can't stand the smell of ammonia. Go ahead and dip a few cotton balls in ammonia and throw them around the garden or yard and see the dogs take off for greener pastures. Need help indoors? The same rules apply, but you can spray the liquid on furniture instead of dropping cotton balls everywhere.

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.I would also suggest the citrus peels. Oranges or grapefruits I think work just as well; do not use toxic things like mothballs, as that is even more horrible than outdoor cats. Are these cats bothering you or your cats or both? Are they spraying their scent around? If your cats are indoors all the time, you have a few more choices. I used a lemon scented Mr. Clean splashed over the places the stray cats were spraying, and that covered the smell and seemed to deter them. If your cats don't go outside, or you keep them in your yard, you might also try a cat repellant that you can buy in places like Walmart. There are different kinds. Might work.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.

You might try orange or grapefruit peels as well, as I think it is the citrus smell that deters them.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.
