Are there any plants or natural remedies that would deter cats from using my flower beds as a litter box?

My neighbor's cats like to use my wine barrel planters on my front porch. I can't stand cat poop especially when I walk out or in my front door. It is really embarassing when I have company. Please Help.

Are there any plants or natural remedies that would deter cats from using my flower beds as a litter box?
A couple things I've tried:


Spreading citrus peels


Sprinkling cayenne pepper


Planting Coleus-Canina





The best for me was the cayenne and the coleus-canina. The cayenne did add some color to ground until it rained or I watered. The coleus canina has a strong odor, so one plant seemed to work for my entire front garden area.

Reply:Just go yell at your neighbors and tell them to do something about their cats or you'll do something bad to them. If you don't prefer to take that approach, i can't really help you but i'm sure there is something that smells bad to cats but not to you (ie toothpaste) that could work by placing it around your house but I would not be an expert on that.
Reply:you can feed them some food laced with castrol beans
Reply:There is a Citronella plant. There are many stay away sprays and most are strong citrus smell. Too bad there are not motion detector water sprinklers... when they hit the grass they get sprayed!!! I love cats, but neighbors that are rude and let theirs run free - is rude. Put the poop on their doorstep when you find it. Maybe they will leave them indoors.

Reply:THE MOTHBALL IDEA IS GOOD AND IT WORKS OCCASIONALLY, YOU CAN ALSO BUY "BOBCAT URINE" AND SPRAY IT ON YOUR GARDEN....IT'LL KEEP THE DOMESTIC CATS AWAY....THE "GET OUTTA MY GARDEN" THING IS GOOD TOO.......BUT BETTER YET IS A "HAVAHEART TRAP" AND A CAN OF TUNA. THIS ALLOWS YOU TO PHYSICALLY REMOVE THE UNWATED CATS TO A NEARBY ANIMAL SHELTER WHERE THE CATS WILL GET BETTER TREATMENT ANYWAY AND THEY WILL BE FED BY HAPPY LITTLE SHELTER MANAGERS AND YOU ALL LIVE HAPPILY EVER AFTER, THUS NO CAT, NO CAT POOP, NO EMBARRASSING ODORS AND YOUR COMPANY WILL NOT BE TALKING ABOUT YOU BEHIND YOUR BACK AFTER THEY LEAVE.
Reply:Garlic is supposed to keep cats out of sandboxes. I don't suppose it would hurt plants since you can make garlic pest-sprays. Just get some cheap garlic powder in bulk, and sprinkle it on every so often.
Reply:water flowers and sprinkle black pepper liberally on the bed. It won't hurt plants or animals, but the will sneeze their way home and not come back. Also works well mixed with flour to keep dogs from digging in the trash cans.
Reply:Try mothballs
